Ultrasonic water flow meter

Ultrasonic Water Meter

Ultrasonic water meters are flow meters that use high-frequency sound waves to measure the water flow rate in a pipe. As the sound wave travels through the water, it is affected by the velocity and direction of the flow. Can calculate the flow rate of the water by measuring the time it takes for the sound wave to travel through the water and the change in frequency of the wave. The flow rate calculates the total volume of water that has passed through the meter. Can use this information to monitor water flow and consumption in various applications, including residential, commercial, and industrial settings.

4G Rs485 Telemetry

4G RS485 telemetry is a type of remote communication system wireless technology and the RS485 serial communication protocol to transmit data over long distances. It is commonly used for remote monitoring and control of devices and systems, such as water and gas meters, environmental sensors, and industrial equipment. 4G RS485 telemetry systems typically consist of a transmitter and receiver, which connect to a device or system that needs to be monitored or controlled. The transmitter sends data from the device or system over a 4G wireless network to the receiver, typically located at a remote location. The receiver then converts the data into a form that can be interpreted and used by a computer or other device.


We implemented a wireless water flow and consumption monitoring system using advanced sensors and software(IoT Platform) to meet these challenges. The sensors were installed throughout the buildings, including restrooms and other high-use areas. The data collected by the sensors was then transmitted wirelessly to a central server, where it was analyzed and used to generate reports and alerts. The system is designed to accurately measure and track water usage in real-time, allowing it to identify waste areas and implement corrective measures to reduce overall consumption.

Overall, the project was a win-win for both company and the environment. The company reduced its water usage and environmental impact while improving efficiency and saving money on water costs.

Case study: Advanced temperature monitoring and control in a radiant cooling system for a wide floor surface area.

About client

Our client is a leading solutions provider in the Radiant cooling and heating industry. They are awarded the prestigious WWF Climate Solver for their radiant cooling solutions. Over a decade, they have provided innovative, sustainable, and scalable energy efficiency solutions in various sectors ranging from Pharma, Food, Construction, IT, Manufacturing, Warehousing, Defense, Power, etc.


Radiant cooling systems are an efficient and effective way to regulate the temperature in a building or space. These systems work by circulating cool water through pipes or tubes beneath a structure’s floor, walls, or ceiling. This cool water absorbs heat from the surrounding air, helping keep the space comfortable. The challenge with radiant cooling systems is accurately monitoring and controlling the temperature of the floor surface. If the floor is too cold, it can be uncomfortable for occupants and may result in decreased energy efficiency. On the other hand, if the floor is too warm, it may not effectively cool the space. Another one is to monitor the temperature for a wide floor surface area.


7 Channel Actuator controller (Gateway)


To address the challenge of accurately monitoring and controlling the temperature of a radiant cooling system, a custom solution has been designed using Bluetooth Low Energy (BLE) surface temperature beacons, a wireless thermostat, and a 7-channel actuator controller (gateway).

  1. Install BLE surface temperature beacons on the floor in a representative location. These beacons continuously measure the temperature and transmit the readings at a fixed interval (1 minute by default).
  2. Data received from wireless surface temperature beacons are sent to the thermostat, and the thermostat will transfer the data to the 7-channel actuator controller (gateway)
  3. Program the wireless thermostat to control the temperature of the space based on the temperature readings from the wireless surface temperature beacon and to measure the space’s humidity to prevent floor condensation.
  4. Program the 7-channel actuator controller (gateway) to receive temperature readings from the thermostat and to control the flow of cool water through the radiant cooling system based on these readings.
  5. Monitor the system’s performance using the thermostat and the 7-channel actuator controller (gateway). Adjust the settings as needed to ensure that the floor’s temperature is maintained within a comfortable range.

This solution offers precise temperature control, energy efficiency, comfort for occupants, and easy maintenance and calibration. By accurately controlling the floor’s temperature, the radiant cooling system can operate at maximum efficiency, reducing energy consumption and costs while ensuring the comfort of the space’s occupants. Wireless technologies also simplify the installation and maintenance of the system, as it eliminates the need for wiring between the various components.


  • Precise temperature control: The wireless surface temperature beacon allows for real-time temperature monitoring of the floor surface, ensuring that the radiant cooling system operates optimally.
  • Energy efficiency: By accurately controlling the floor’s temperature, the radiant cooling system can operate at maximum efficiency, reducing energy consumption and costs.
  • Comfort: By maintaining a comfortable temperature range, the radiant cooling system helps ensure the convenience of the space’s occupants.
  • Easy maintenance and calibration: The BLE surface temperature beacon, thermostat, and 7-channel actuator controller (gateway) are easy to access for maintenance and calibration, ensuring the system operates at its best.

Project Requirement


Many industries depend on groundwater for their functions. Still, inadequate monitoring and management of groundwater levels can lead to depletion and contamination of this vital resource. Hence, our customers need to monitor the Groundwater level parameters (level, temperature, barometric pressure, and pressure) as per the CWGA Guidelines.

Traditional groundwater monitoring methods often involve wired sensors and data transmission systems, which can be expensive and labor-intensive to install and maintain.

BT Product

A groundwater level data logger is a device that measures and records groundwater levels over a while. It typically consists of a water level sensor, a data logger, and a power source.

The water level sensor is used to measure the groundwater’s depth below the surface. The data logger is used to store the data collected by the water level sensor and may also be able to process and transmit the data.
The power source is used to power the data logger and the water level sensor. It could be a battery, a solar panel, or an external power source.

Telemetry is the process of transmitting data from one location to another. It can be done using various technologies, such as Lorawan or  cellular. In groundwater level monitoring, telemetry can transmit data from the data logger to a central monitoring system.

By combining a groundwater level data logger with telemetry, industries can monitor groundwater levels in real time and collect data over long periods. This can be useful for understanding changes in groundwater levels and managing water resources sustainably.
