Meters and Measurement Devices for Exact Consumption Data Acquisition

Other than metering performance, the ultrasonic heat meter, remote control (brass, threaded type) also has the functions of controlling the opening and closing of valve via wireless connection with indoor temperature controller and management system, as well as uploading the indoor temperature to the management system.

This series heat meter is powered by M-Bus and battery, efficiently enhancing the service life.

In addition, this heat meter adopts clock chips to provide ultra-low power consumption, capable of detecting low flow rate.
