The high performance level transmitters are based on manufacturer’s years of experience with ultrasonic level measurement. Whether for liquid level measurement in sumps or tanks, for tank contents measurement, or open channel flow measurement, the ultrasonic level transmitters provide the answer. Installed on the tank roof, or above the liquid surface to be measured, the transmitters give analogue output proportional to liquid level or transmit HART digital data. The unit is an intelligent compact ultrasonic level transmitter with 4-20 Ma output offering HART protocol as option. Local reading is ensured by a plug-in display which can be removed if displaying is not needed.
