APPLICATION
◆Measuring
the volume of cold (hot) potable water passing through
the pipeline.
FEATURE
◆Dry
type,
single jet,
small, light, 8 digits, magnetic drive, magnet
resistance, 360 degrees free rotating register,
corrosion
resistant
body, inlet strainer, Low Head loss,
easy and long term clear reading etc.
◆Plastic
painted or chrome coated, or nickel coated
available.
◆Counter
vacuum sealed, it does not get frosted. Fit for both
cold and hot water. Protecting cover available upon
customers' request.
WORKING PRINCIPLE
◆Water
passing through the water meter, causing the turbine to
turn.
◆The
turbine rotation is magnetically transmitted to the
register on which the reading is made. Reeding is
accomplished by means of pointers and numbered
cylinders with high-resolution. Shock-resistant
dial.
