Payment & Shipping Terms:
This type of water meter is multi-jet dry type water meter with plastic body and used to measure the total quantity of cold potable water which consumed in household or a resident unit, passing through the pipeline.
Multi-jet velocity meters.
Magnetic drive, dry-dial, vacuum sealed register, frost resistant, keeps clean reading for long time.
High sensitivity of measuring accuracy, the starting flow rate of the meter size DN15mm is 8 liters or less.
Selected high quality Nylon materials of new-style nontoxic and pro-environmental for steady, reliable characteristic.
The meter body’s color can be black, blue, yellow and green for option.
The mechanism has 5 digits and 4 pointers, 8 digits and 1 pointer for option.

The water flows through the meter’s strainer and into the measuring chamber where it drives the impeller. A drive magnet transmits the motion of the impeller to a driven magnet located within the sealed indicator. The magnet is connected to a gear train which translates the impeller’s rotation into volume totalization displayed on the register dial face.
