Product details

1、 Overview
The ZY-LWQ gas turbine flowmeter is a new generation of high-precision and highly reliable gas measuring instrument that has been independently developed by drawing on advanced technology of flow instruments at home and abroad, optimizing design, and integrating theories of gas mechanics, fluid mechanics, electromagnetics, etc. It has low-pressure and high-pressure measuring performance, multiple signal output modes, and low sensitivity to fluid disturbances. It is widely used for measuring gases such as natural gas, coal to gas, liquefied gas, and light hydrocarbon gas. This type of turbine flow product itself does not have on-site display function, and only transmits flow signals in the form of pulse signals for remote output. The instrument is inexpensive, highly integrated, and compact in size, making it particularly suitable for use with computer control systems such as secondary displays, PLCs, and DCS. This type of turbine flowmeter is an explosion-proof product, with an explosion-proof rating of: ExdIIBT6。

2、 Product Features
·Alloy turbine with higher flow stability and corrosion resistance
·Imported special bearings with long service life
·The isolation between the measuring room and the ventilation room ensures the safety of the instruments
·Wide flow range (Qmax/Qmin ≥ 20:1), good repeatability, high accuracy (up to 1.0 level), low pressure loss, low starting flow rate, can
Up to 0.6m3/h
·The instrument has explosion-proof and protective functions, with explosion-proof markings of Exd Ⅱ BT6 and Exia Ⅱ CT6, and a protection level of IP65
