Iot vs scada

You will discover that nearly every industry around you runs through a SCADA system. It is a system upon which all industrial work largely relies. We can even say that SCADA is an automated control system that gives managers information about the state of the enterprise. It is operated in nearly all industrial verticals to access the whole plant from the control room. Let’s learn more about SCADA and its existence in previous years.

Before SCADA, the Industrial Revolution took a dramatic turn in the form of Industry 3.0, which began with partial automation, with industrialists using memory-programmable controls and computers. During this revolution, the Internet was a breakthrough for everything around us. The invention of computers and software has been hailed as revolutionary and led to task automation, also known as intelligent automation.


The SCADA system is the supervisory control and data acquisition system of software and hardware that allows enterprises to manage processing from regional and outlying locations. It helped industries monitor and control industrial equipment in every segment, like development, manufacturing, production, and fabrication. Many sectors like water, wastewater systems, power, oil and gas, manufacturing, and food production use SCADA systems to collect, monitor, and real-time data. Furthermore, with the introduction of SCADA, it was much simpler to manage industrial processes and directly interact with devices like valves, pumps, & motors.

A basic SCADA system comprises to form a functional SCADA system.

  • human-machine interface is an input-output device allowing a human operator to control the data. 
  • The supervisory system approach is a communication server that connects the human-machine interface with other equipment like plc and sensor devices. 
  • Remote terminal units transmit the recorded data to the supervisory systems.
  • Programmable logic controllers (PLCs)  work through sensors and provide real-time industrial processing monitoring.
  • Communication infrastructure
  • SCADA programming

How does the Scada system work?

Data Acquisitions:

SCADA systems are essential and reliable because they provide a wealth of data to make intelligent business decisions. Sensors, controllers, and real-time units play an important role in data collection. The real-time system consists of many sensors that collect real-time data. And for the whole system to work perfectly, it is essential to monitor these sensors.

Data Communication:

SCADA uses a wired network for communicating effectively between sensor devices and users. It securely fetches data from sensors for effective data communication and improves efficiency.

Data Presentation:

Since a large amount of data are collected via sensor devices, converting this data into valuable information evolves the most critical task. As it becomes complex to handle a large no. of sensors simultaneously, At the same time, the SCADA system uses a human-machine interface (HMI) to collect all sensor data and convert it into usable information.


As SCADA utilizes Human Machine interfaces, the communicated data ought to be observed by humans. It delivers access to numerous control units and PLCs.

Controlling and monitoring :

SCADA systems use controllers to operate each device. These controllers help turn ON/OFF each device, and it works automatically without human intervention, but in specific conditions, it is to handle manually.

Regarding technology, the future of industrial automation is evolving, so robots are replacing people. And now, it is the time for a more extraordinary revolution with the introduction of Industry 4.0

IoT is an evolved concept that enterprises now widely accepted due to sensor-based techniques and data-driven methods. It allows manufacturers to develop their business reasoning and improve their loopholes to serve better quality. For example, if a SCADA system produces complex reports, an IoT solution can improve the format and deliver them more simply and efficiently. Moreover, technology solutions help to share information directly with the head office or any specific person.

How is IoT Carried over SCADA and PLC?

Programmable logic controller(PLC) is the technology that has been a pal to SCADA Over the past few years. But obsolete because of technical improvement. It can automatically initiate and prevent operations and generate alarms if a malfunction occurs. Even PLCs acquire data from sensors, which process and dispatch it further per the programmed parameters.

Most of the statistics from many industries have concluded that the power of SCADA systems was essential to the Industry 4.0 revolution. Still, it is limited to having an utterly connected ecosystem to handle the rest of the business. However, the Industrial IoT (Internet of Things) has entered the market and has evolved into a superior technology compared to traditional SCADA and PLCs. Undoubtedly, its intellectual capabilities are easily adaptable to today’s modern industries.

The Industrial Internet of Things emerged as a technology implemented on top of SCADA. Parameters such as scalability, and data analytics, appeared with the advent of disruptive IoT technology.

The Internet of Things has brought a wave of new business to change the SCADA landscape. The data generated by SCADA systems is still the data source for Industrial IoT. Industrial IoT focuses on analyzing detailed machine data to improve performance, whereas SCADA used to focus on monitoring and control.

How IoT Differs from SCADA

1Scalability In SCADA systems, due to the standard architecture, when the number of users increases, it stains performance drastically. It also carries comprehensive reports from factories in different nations and areas from the significant plant.IoT can receive and process a vast amount of sensor data and allows you to connect everything that matters using protocols such as MQTT, HTTPS, XMPP, COAP, REST, Etc. which provide on-demand scalability through a serverless architecture
2Data Analytics The primary SCADA usage is for day-by-day plant operation and ingestion and storage of a finite amount of data without preserving historical data for deeper analytics.IoT involves long-term data retention to further analyze the data to predict maintenance schedules, reduce overall downtime, and extend equipment life. On top of predictive analysis and preventive maintenance, capabilities are part of it supported by the Machine Learning module.
3StandardizationSCADA systems mainly use Open platform communications to collect data, a model that has stood the test of time. Still, its main disadvantages are DCOM technology and devices cannot contain/exchange data with each other regardless of the footprint.The main goal of Industrial IoT is to standardize sensor networks, data collection,
and aggregation. IoT standards such as OPC UA are already being used to define secure, real-time communications across the enterprise with various control devices and sensors from multiple vendors. Security is built into IoT standards with support for MQTT, HTTPS, RAML, etc.
4InteroperabilitySCADA systems cannot be easily integrated with devices from different manufacturers. Sometimes even different versions from the same manufacturer make them difficult to interchange. Thus, SCADA provides distributed business processes that operate independently.Industrial IoT ecosystems remain fragmented, but protocols such as MQTT allow platforms to connect across all devices, regardless of vendor.

What will happen next after comparative analysis?

In summary, both SCADA and IoT involve sensors and data acquisition. They differ in many aspects but share a common goal. SCADA is not a complete control system, but the Industrial Internet of Things comprises many interconnected devices. It enables remote control of appliances across different networks and architectures. But integrating IoT with a SCADA system provides a comprehensive understanding of the entire industrial premises more straightforwardly. In SCADA, while you have to generate analytical reports manually, with an IoT-powered solution, you can automate this process to save time and get quality output.

Why Should You Utilize a Wireless Level Monitoring System for Large Storage Tanks?

Industrial management is now driving ahead by the rise in technology. Practically every industry operates the full potential of technologies like the Internet of Things to obtain enormous profits from intelligent solutions.

Large tanks are using in plenty to stock solutions of various forms. These vessels are hugely assembled for large volumes and require an intelligent system that can recognize every possible field to keep the fluid safe against leakages. Therefore, a level monitoring system contributes real-time assistance to the manufacturers and the automatic functioning of the assets (large tanks).

Level estimation is the little distance separating the starting point(base of the storage vessel) and the material’s surface in the storage container.

An IoT Power level monitoring solution exact estimates of the liquid level present inside the container and displays the readings on the user dashboard. It acts within sensor functioning, with communication gateways mediators within the sensors and the interconnected dashboard. Following the same IoT architecture, a level monitoring system tends the most active and splendid concept to monitor levels in large containers.

Let’s study more regarding the functioning of a level monitoring system and its effect in conserving the level records of large tanks.

Observing the Levels of Large Storage Tanks through IoT

The Internet of Things technology is molding enterprises quickly by its imaginative concepts and innovative procedures. It practices automation as the central mechanism to achieve manufacturing tasks better and implement appropriate data for review.

In large-scale industries, liquids are Stock in mass amounts, Measure levels, an automated system will be more profitable than manual processes. While manual surveillance, the plant managers need extra time apart from their schedules for measuring and calculating the levels of the tanks. It would help if you had a well-organized notion that seamlessly executes every responsibility and implements specific level readings in pharmaceuticals, beverages, or the oil and gas industry. Thus, IoT technology can be one of the choices to implement within the sectors for more growth.

Why is Level Monitoring Important in Large Tanks?

Managing Stock

Level monitoring in large industrial tanks is needed to sustain the stock levels of the manufactured product to fulfill up with sufficient supplies when required. Thus, keeping control of the records is highly important, including everyone who practices the content from the storage containers. It results in enhanced product value and records the loss of the saved liquid to maintain clarity.


Industries dealing with poisonous liquids or synthetic liquids store their stocks in large containers. If tanks fill above their capacity, it may cause dangerous effects in industries due to overspilling in open containers. The acidic, reactive, flammable, or hazardous substance result in catastrophic results when spilled or leaked through unknown mediums. Therefore, a level monitoring solution allots setting threshold limits. You’ll be sent an instant signal on your device as soon as the liquid passes the set limit. It prevents overfills and identifies leakages to match environmental regulations.

Industry Efficiency

Reliable level monitoring improves the processability within the industry. Suppose a plant facility needs to keep the stocks readily available at all times, and the storage containers fill with less quantity. In that case, the plant will produce extra expenses to manage additional storage vessels for the new Stock. Therefore, you can efficiently use storage spaces within the existing tanks with an intellectual level monitoring system. it is an economical way to prevent the extra cost of acquiring more space and vessels into the plant

Consistent Supplies

Many industrial processes need a steady supply of liquids, and it isn’t easy to maintain if the stocks differ in quantity. Also, in the case of providing the products, it generates a lowering brand image if there are breakers in the supply lines. Therefore, it becomes necessary to keep a conventional measurement of the liquid inventories. The level monitoring solution enables you to keep an appropriate range of process levels in the storage tanks and thus, bypasses any interference caused due to fluctuating supplies.

IoT technology has come up with a brand-new method of measuring the levels of hugely constructed tanks. As an industrialist, you can modify your processes with automation and get effective results. Since massive storage tanks are tough to manage, it is a splendid idea to perform a technological solution that provides accurate readings and other benefits. Level monitoring needs in almost every large-scale industry, installing an IoT-powered solution will raise your industry growth to the highest potential.

IoT based Level Monitoring system for Industries

If you are still applying the traditional methods to estimate the liquid levels, don’t you think you need to upgrade the technology to increase industrial productivity? Huge industry sectors like oil and gas, beverage, pharmaceuticals, or water use various storage vessels or containers to stock liquids. To monitor these liquid levels manually is quite tricky. Earlier, applied many methods to check the liquid levels in any organization but identify some drawbacks. Let us see a few of them.

Traditional Procedures to Check the levels

The Unsteady liquid levels are pretty challenging to measure & control for the managers in previous times. Several trials were conducts to record the levels like level control in dams and their regular release for agricultural purposes. Earlier, it involved no technology. The managers assumed the total amount of water required in an appropriate year and took decisions accordingly. Anyhow it is not accurate to save water or any other liquid stocks.

In the case of Oilfields, plummet is used to identify the fuel levels, but it had its drawbacks:

  1. There was always action to performs, which prevented the operators from their regular duties.
  2. There was no clear description of the collected data.
  3. Workers find it very hard to estimate the liquid levels in pressurized vessels.

Hence the drawback interfered with the effectiveness of the visual level analysis. 

 A different approach is sight glass which reveals the position level of liquid in a tank. This method visually indicated the liquid level and was exposed more conveniently than other manual gauging tapes, dipsticks, or rod dipping. However, the hindrance of using this method was that the glass could be messy and susceptible to damage. Also, it was not a good idea to measure hot acid or flammable liquids, and it might damage the measuring glass.

Monitoring the liquid levels is an experimental journey. With IoT solution, it reaches new heigh and performing well. The industries are now changing themselves smartly with the help of IoT technologies. We can say that IoT is climbing the industrial performance by introducing user-friendly solutions like liquid level monitoring. Therefore, businesses are turning towards technology. so it becomes convenient to measure the levels & improve the inclinations of industrial assets 

Potential causes to measure liquid levels 

Security: In Industries or Factories, Use boilers require a certain threshold to avoid the over-spilling of liquid due to excessive boilingIf there’s such a state where the hot water level rises, a dangerous condition can develop, harming the surroundings. A level monitoring sets a threshold value where the water level increases. It alerts you to take action.

Caution:  When you use various vessels to store multiple kinds of liquids, there are chances of liquid spillages, which are valuable to clear out. Save the worthless money spend on cleaning by using a level monitoring system. It sends real-time alerts as the tank overfills, allowing you to make a better decision.

Efficiency:  The solution uses advanced algorithms and intelligent techniques to provide you exact liquid levels. It allows a fully automated and secure system with which you can perform industrial operations at high levels.

Providing accurate monitoring of levels in heavy storage tanks, increased plant efficiency, maintained assets records, and allot correct values in each segment.

Perhaps, With the rise in industrial productivity due to consumer requirements, IoT solutions’ usage will increase in the upcoming years. Using a liquid level monitoring system to enhances industrial productivity will be added value to industrial processing.
