Class C Cold (Hot) Water Meters DN15-20(mm)
Volumetric Cold Water Meter – Considered to be the world’s most successful household water meter, it offers unparalleled precision and high performance measurements with durable and tamper-proof construction as well as safety.
This type of water meter can be used for a remote reading transmission system as equipped with a built-in sensor.
Application
–Measuring the volume of cold (hot) water passing through the pipeline.
Also suitable for pure water.
Feature
–Low start-up flow rate.
–Volumetric rotary piston principle of measurement.
–LXHY-15～20 is no location limitation for installation.
–Accuracy is not to be affected wherever installed at a horizontal, vertical or inclined pipeline.
–Register is sealed with a special liquid to keep a clear reading in long term service.
–Mechanism use of high-quality material to ensure a stable characteristic.
–Accurate measurement with conformity to ISO 4064 class C.
–On request, the series can be equipped with a kind of remote transmission device.
