ToughSonic REMOTE 50

Maximum Range 50 feet (15.2 Meters)

The ToughSonic REMOTE 50 is a remote liquid level sensor with a maximum range of 50 feet (15.2 meters). This digital sensor is designed for accuracyUltrasonic sensor stainless steel housing and long-term durability in remote monitoring applications. With a stainless steel housing, full epoxy potting and IP68 rating, it operates in the harshest climates. It comes equipped with Senix Lightning Guard, a system that protects both power and communications circuits from repeated electrical transients of up to 7 kilovolts. The ToughSonic REMOTE 50 uses up to 20% less energy than the ToughSonic 50. It is fully configurable with SenixVIEW software. This sensor is mounted on bridges, piers and tanks all over the world in mission-critical remote level monitoring applications.


The ToughSonic REMOTE 50 is available in three different housings. All sensor features are available with any housing


Our Standard Model (U50) comes in a 2.1 inch (53.34 millimeter) smooth 316 stainless steel housing for easy clamping.

Rear Mount

The Rear Mount Model (U50R) adds a stainless steel end cap with 1.5 inch NPT threading to the 2.1 inch smooth standard housing.

PVC Model

The PVC Model (U50P) is packaged in a 2.5 inch PVC housing with 2.5 inch NPT threading on either end for tank level applications.

Serial Interface

The ToughSonic REMOTE 50 is available with one of the following Modbus serial data interfaces.

Modbus RS-232 serial data interface


Modbus RS-485 serial data interface
