Location: Home -> Products -> Valve -> Electric valve -> Ultrasonic heat meter

Features:

The use of high-quality imported transducers ensures a high standard and stability of flow measurement.
There is no mechanical movement, no wear and tear, not affected by bad water quality, and low maintenance cost.
Low starting flow.
It can be installed horizontally and vertically, and the rotating head can meet different directions.
Reading requirements. Pulse, M bus and S485 bus output interfaces to realize remote data transmission,
Centralized control. Automatic error diagnosis function to ensure safe and accurate operation.
The battery life is more than 8 years.
Both heating and cooling (both heating and cooling can be measured).
The inlet and return water temperature is optional, which is convenient for construction and installation.
