  • Page 9: Operating Principle

    3. Operating principle The flow measuring principle is based on ultrasonic measurement method. The ultrasonic signal is transmitted alternately in either of the two directions along the measurement part. The flow value is calculated from the transition time difference between the ultrasonic waves with identical wavelength that was send in the right and opposite direction.

    5.2.1.2. Customer temperature sensors Only approved and matching pairs of temperature sensors with 2-wire connection method could be used. Customer temperature sensor connection procedure: Before installation check that the temperature sensors are paired with each other (T1 with T2). By means of pliers remove the protective caps from the two leftmost sealant holes in the bottom part of calculator enclosure (hole 1 and 2). Insert the wire of supply temperature sensor T1 wire through the hole 1 and the return temperature sensor T2 wire through the hole 2.
