ISEN Tuning Fork Level Switch is a point-level detection device designed to detect whether a liquid, powder, or granular material has reached a defined level inside a tank, vessel, silo, or hopper. Instead of continuously measuring the level, the device provides a reliable switching signal when the material reaches or leaves the sensing point.

ISEN Ultrasonic Level Transmitter is a non-contact level measurement solution designed for continuous monitoring of liquids and other materials in tanks, vessels, and process systems. Instead of placing the sensing element directly into the measured medium, the transmitter uses ultrasonic waves to determine the distance between the sensor and the material surface.
