Mechnical flow meter​

Mechnical flow meter

1  Description

The flowmeter operates on the float measuring principle. The measuring section consists of a metal cone in which a float can move freely up and down. The medium flows through the flowmeter from bottom to top.

The variable area flowmeters are suitable for measuring gases, vapors and liquids with specialty of solid, steady and reliable. CMDKW series are instructions type, and LZDW series are with electronic display and electronic signal output(4~20mA, compatible HART Protocol). The flowmeters are available as inlet or outlet pressure regulator. It also select install 1 or 2 limit switches.
