IV. Installation and Maintenance
1. Choose the water meter with a suitable caliber according to the public pipeline and the flow rate customer required
2. Meter should be installed in the straight section of the pipeline, the length of the straight pipeline between water meter and the forward valve should not be less than 10 times of the meter DN, and that between the water meter and the afterward valve should not be less than 5 times of the meter DN, maximum valve opening suggested when meter being used.
3. Before installation, the trashes in the pipeline should be removed to avoid malfunction of the meter
4. A valve should be fixed in front of the meter to cut off water source when repairing.
5. Meter should be installed horizontally with the dial facing up, the arrow on the cover should be of the same direction as the water flow.
VI. Announcements
1.Installation site of the water meter should be far away from large area metal and strong electromagnetism devices, guaranteeing no interference of signal receiving or transmitting.
2. Water meter installation box or chamber panels should avoid composed of metal material, ensuring the transmission reliability of the wireless signal.
3. No usage of metal well shutter above the meter fixed in underground chamber.
VII. Accessories
Coupling 2pcs, Connecting nuts 2pcs, Seal ring 2pcs, One instruction book, One packing list.
VIII. AfterSales Service
We guarantee to be responsible for the rightly fixed water meter under normal flow, whose inner mechanism parts breakdown or malfunction are really caused by manufacturing or quality factors(Freezing excluded), and in charge of its repairing or exchanging under the situation of lead sealing integrity.
