Ultrasonic level transducer ULT21

Coming soon

ULT21 transducers are designed to measure distance/level based on ultrasonic technology. Compare to the previous serie of transducer, ULT21 has a wider measuring range - up to 15m and a higher protection grade - IP66 / IP68.

Additionally ULT21 can be used to measure the filling of tanks, to count the flow and level measurement in open channels.

Built-in LCD display, which, together with the buttons creates a local user interface allows for any change of operating parameters and viewing the current status of the device, including the reading of measured values.
