LXXG-50-300MM
S.H.Meters
The Woltman water meter is a meter used to measure the flow of water. It uses a technology called the "Woltman measuring principle" to measure the flow of water by passing water through a rotating turbine, which drives the metering device.
Application
Measuring the volume of cold (hot) water passing through the pipeline.
water meter is used for home or apartment
