DN15 DN20 Volumetric Brass Cold Water Meter R160

Brief introduction:

The volumetric water meter is mainly composed of a meter case, a counting mechanism, a piston metering mechanism, etc. The counting mechanism adopts the form of liquid seal, and the reading part of the word wheel is sealed with the anti-corrosive liquid and keeps the reading part clear for a long time, separated from the use of water.Sealing liquid has the characteristics of anti-freezing, anti-fog, anti-fouling and so on.

Characteristic:

With piston metering structure, the metering of water meter is more accurate, the starting flow rate is 3-4L/H,  measuring range is more wider, R160.Horizontal, vertical optional installation.

Working condition(s):

Water temperature 0.1~30℃, working pressure≤1MPa.
