The Mobrey Integral ultrasonic level sensor switch is intended for level detection at a fixed point when liquid fills the gap between the crystals. It has polyphenylene sulphide construction and two open-drain FET transistors (one conducting when the sensor is wet and the other conducting when the sensor is dry) output type. This switch It has electric voltage ranging between 18VDC/AC and 30VDC/AC.

Note:
If the liquid to be monitored is flowing, the device should be fitted with the gap inline with the flow. In storage tanks, it should be fitted with the gap vertical unless the liquid is highly aerated when it should be angled.
