B12 VI-B Ultrasonic Heat Meter is an innovative heat meter with static flow sensor based on the ultrasonic measuring principle. B12 VI-B is designed for measuring the use of heating in which water is the heat/cool bearing medium.
It utilizes ultrasonic measuring methodology and microprocessor technology. All calculation and flow measuring circuits are designed on one single board, thus offering exceptional accuracy and reliability. B12 VI-B gives importance to flexibility with its programmable functions and install-uninstall communication units.
With its size options from DN15 to DN40, it enables flow rate metering from 0.03 m3/h to 20 m3/h.
