Accurate and reliable

Accurate and reliable sensor. Used to monitor water level continuously in a water level control structure.


We use it to measure levels of different tanks and it works perfect. Good packed and good communication during the order process.

Low votlage, high accuracy and relibility

Maybe the only ultrasonic sensor powered 5V DC which range up to 5m, whit an accuracy of 1mm and high reliability.

Reliability and Robustness, low cost
