Flow meter
DXLZZ (D) W micro flow metal tube float flowmeter

I. Overview
DXLZZ (D) W series is a micro-flow metal tube float type flow measuring instrument that can measure liquid, gas or steam. The meter uses the variable area measurement principle. The measuring part is composed of a tapered measuring tube and a float, which is sturdy and stable. And a wide range of applications. The connection method includes horizontal connection or vertical connection, and can also be equipped with a pressure regulator (constant flow valve) that changes the inlet pressure or the outlet pressure. It is widely used in petroleum, chemical, chemical fiber, steel, food, light industry, pharmaceutical and other industries. Tiny flow measurement and process control.
The DXLZZW series is an on-site indicating instrument, which can be equipped with one or two intrinsically safe explosion-proof alarm switches (requires associated equipment); the LZDW series is an electric remote transmission type instrument that outputs 4-20mA current signals (compatible with HART communication protocol) At the same time, the LED light beam is used to indicate the flow on the spot.
