JFA911 split-type ultrasonic level sensor meter

widely used in oil, chemical industry, water treatment,
water conservancy, steel, coal mine, electric power
and food processing industries. It is applicable to acid,
alkali, salt, anticorrosive, high temperature, explosion proof and so on

Category: Ultrasonic level meter

产品描述标题.jpg

       The series of ultrasonic level difference sensor is non-contact level measurement instrument. 

       It is using ultrasonic reflection principle to detect the liquid level of fouling fence around. 

       And calculate the difference of liquid level. The instrument consists of an ultrasonic probe and host. 

       Both are filled plastic sealed structure.


特点标题.jpg

      The distance of mainframe and ultrasonic probe can be 1000 meters.

      Good anti-interference capacity.

      Full sealing structure, anti-corrosive.

      Low blind area, high sensitivity.

      Provide 6 relay switch value signal, relay status can be programmed.

      AC or DC are optional.

      Provide remote control to set parameters, convenience for operation.
