LXLC-300 Horizontal installation
dry dial detachable large caliber cold water metering for water works
1, Horizontal turbine woltmann cold water meter(DN250)
Brief introduction:
Horizontal spiral 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..
Characteristic:
Wide measuring range, accurate measurement, large circulation capacity, small pressure loss, technical index up to GB/T778.1~3-2007 standard, strong structure. Long service life, 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, DN50 and above use flange connection (iron shell).
The interchangeable, removable measuring mechanism can be easy removed from the body for checking, maintaining and replacing, no needs to dismantle the body form the pipe;
Working condition(s):
Water temperature 0.1~30℃, working pressure ≤1MPa.
