Meters and Measurement Devices for Exact Consumption Data Acquisition
The ultrasonic heat meter, 270 series (cast iron, flange type) adopts a single-channel line and circle aluminum integrator with higher protection grade for the measurement and display of heat absorbed by the flow water. The vertical integrator offers convenience for users to read data.
Basic Controls uses a cast iron made meter line to enable the ultrasonic heat meter to maintain outstanding physical and mechanical properties. Besides, this series heat meter is connected by flange to facilitate the installation and disassembly.
