Application:
Measuring , memorizing and displaying the volume of cold(hot) water passing through the pipeline.
FEATURE:
1. Large flow capacity and small pressure lose.
2. Antipollution,Builtin stainless steel strainer can save the installation cost. The measuring mechanism can be removable from the body for checking maintaining and replacing.
3.Selected high quality materials for steady and reliable characteristic.
4.Vacuum sealed register ensures the dial kept from fog and keep reading clear in long-term service.
