The U3M-148 continuous level sensor is a field-programable, full-range ultrasonic liquid level sensor that is ideal for small tanks and drum level sensing. Its design is compact, extending just over 2" in height above the tank or drum surface, and it has an operating range of 4 in. to 9 ft. (0.10 m to 2.7 m). The "Mini Probes" 4-20mA output is easily programmed on the bench or in the field with an on-board push button, to set your high and low levels without the need for software and computers. As with all of our standard Ultrasonic models, the U3M series has a PVC housing that is chemical resistant and allows for operating temperatures of -40 to 140˚F (-40 to 60°C).
The U3M’s microprocessor-based circuits provide a temperature-compensated signal for improved accuracy and the ability to filter false echoes produced by peripheral obstructions. Optional RS485 communications are available for computer interfacing and for networking up to 128 sensors. Relay models for alarm and/or on/off control by the sensor can also be provided.
For applications requiring a sanitary interface to the sensor, an optional 316L Stainless Steel transducer face with tri-clover clamp is also available.
