Ultrasonic sensor Sonicont USP4

Delivery Time: approx. 3-4 workdays

Ultrasonic sensor for non-contact level measurement in liquids and bulk solids

  • Easy to operate via Bluetooth® and App
  • Slender design
  • Combinable with measuring tube, this avoids adjustment



The ultrasonic sensor Sonicont USP4 is an ultrasonic sensor for non-contact level measurement and monitoring in liquids and bulk solids. The sensor is designed as a suspension version with a cable outlet or as a screw-in sensor with a cable or plug connection. Thanks to its slim design, the sensor can be inserted through small container bores or installed in thin monitoring wells.
The ultrasonic sensor Sonicont USP4 can optionally be combined with measuring tubes made of PE. This gives the ultrasonic signal a defined measuring path, which means that there are no influences that would affect the ultrasonic signal, for example, from oxidized and uneven level pipes or container walls.
The electronics are designed as a 4… 20mA 2-wire signal. In order to ensure safe operation, especially outdoors, the Sonicont USP4 has integrated surge protection.
Due to its high accuracy, the compact sensor can be used for a wide variety of applications in the field of groundwater and surface water measurements, tank monitoring, wastewater and distance measurements. Using a free app, the Sonicont USP4 can be adapted to the respective operating conditions via Bluetooth® 5.0 LE.
