Submersible Liquid Level transmitter
Introduction
Liquid Level Submersible Pressure Transmitter based on the measurement of the static pressure of the liquid level proportional to the depth of the liquid, and after amplification circuit converts the standard current voltage signal output, establish output level electrical signals depth linear correlation of liquid depth measurement. In the structure, it uses waterproof wire and stainless steel housing sealed connection, snorkel in the cable with the outside world, the design of the internal structure is anti-condensation. Has good stability and reliability, and are widely used in the measurement and control of the water level in the field of environmental protection, water conservancy, power plants, urban water supply and drainage, hydrology exploration.
Application
It can be used for liquid measuring for petroleum, metallurgy, hydraulic, city water supply,
sewage treatment, hygrometry and etc.
Liquid-level testing and control in industrial process
Testing and control in Hydraulic and hydropower engineering
Building Automation System and constant pressure water supply system
