Sell xmh-wk external liquid level alarm @China (Mainland)

I. General Information

XMH-WK External liquid level alarm is a new product. Base on our R&D experience, it is easy to use and no demand on measured material. It only install out of tank. Precision and sensitivity can be on-site adjusted. 

 II. Working Theory

High frequency ultrasonic possesses good penetrability. It can penetrate steel, iron, PVC, rigid plastic and so on. When sound wave meets different material, it reflects.  So installation the sensor out of tank, it can check the level. After liquid level reaches the sensor, sensor will alarm.
