Product description:
The hermetically sealed water meter is separated by rubber seal strip, and the sealing performance is good at room temperature. The technical gear of liquid seal meter is completely liquid sealed by special liquid, so it will not be affected by water quality, and the reading can be kept clear for a long time. It has no water under the lense of counter, can withstand pressure of water, cold and freezing weather, its figures show that part of the reading can be kept clear for a long time. But the manufacturing process of dry water meter is expensive. Due to the disturbance of external strong magnetic field, rust in water and natural demagnetization, the measurement data will be slower and slower in some case
Performance Characteristics
This water meter is a liquid sealed ,one of wet type water meter. the special liquid encapsulation of counter data wheel for reading windows to keep clear for a long time
water contact parts are made of high-quality anti-corrosion and anti-pollution materials
the connections of DN15-40 used standard screw thread
The connections DN50 are used flanged connection(cast iron body)
It has the advantages of low initial flow rate of wet water meter and clear reading number of dry small meter, which is especially suitable for poor water quality pipe network,.
it has the advantages of low initial flow rate of wet water meter and clear reading number of dry small meter.
With high quality materials, the performance is stable and reliable; the measuring precision reaches the ISO 4064 Class C standard
you can choose different R3/Q1 ratio according to your demand
