Electromagnetic water meter , water flowmeter

The CXLDS electromagnetic water meter consists of two parts: sensor and converter. It is an instrument made according to Faraday's law of electromagnetic induction to measure the volume flow of conducting liquid in a closed pipe.

Electromagnetic water meters are widely used in chemical industry, electric power, water supply and drainage, paper making, pharmaceticals, food, environmental protection and other departments.

1.2 Product Features
