Product Overview


Specification of Mechanical water meters


1, Vane wheel semi-liquid sealed cold water meter (LXS-15Y~65Y)

Brief introduction:

Vane wheel semi-liquid sealed cold water meter is mainly composed of a meter case, a cover, a mechanism counting, a metering mechanism. The counting mechanism adopts the form of liquid seal, water on the surface of semi-liquid sealed water meter, the reading part of the wheel is sealed with the anti-corrosive liquid and separated from the use of water for a long time to keep the reading part clear. The sealing liquid has the characteristics of anti-freezing, anti-fog and anti-fouling, etc..



High accuracy, accurate measurement, convenient maintenance, technical index up to GB/T778.1~3-2007 standard, The separation energy of liquid seal series counter and measured water can keep the indication clear for a long time, High quality anti-corrosion and anti-fouling material used for parts in contact with water, DN15~40 adopts standard pipe thread, DN50 and above use flange connection (iron shell).


Working condition(s):

Water temperature 0.1~30, working pressure1MPa.
