What are the types of water meters
What are the types of water meters
Water meters can be divided into 8 categories according to principle, level, nominal diameter, use, installation orientation, temperature, pressure, and form.
1.According to the principle of measurement and verification is speed type, capacity type water meter.
2.According to the precise measurement standard: A-class meter, B-class meter, C-class meter, D-class meter, the larger the measuring range, the higher the precise measurement level.
3.According to nominal caliber: large caliber and small caliber.
4.According to the application of residential water meter and industrial water meter.
Water Meter Installation Frequently Asked Questions and Instructions
1.Be sure to install the water meter in accordance with the water meter dial or cover tight reminders. “H” labeled for horizontal installation, water meter inside diameter gauge up, water meter case with an arrow on the direction of the pipeline with the direction of flowing water, the water meter upstream should be installed with a regulator to facilitate the replacement of the water meter and maintenance. Upstream should ensure that 10 times the specifications above the receiver section, downstream should ensure that 5 times the specifications above the receiver section.
2.Installation should avoid exposure and freezing, environmental pollution and flooding, conducive to disassembly and reading, winter should be used to prevent cold countermeasures.
3.Engineering construction, pay attention to the maintenance of plastic hoses and wires, prohibit driving plastic hoses to transport the water table, in order to prevent the plastic hoses fall down or wire sheath cracked.
4.The newly installed pipeline to solve the pipeline to carry out the removal of impurities in the pipeline will be cleaned neatly to avoid water meter blockage. When installing the water meter, pay attention to the length of the water meter connection. When the spacing between the two sides of the pipeline beyond the coupling length of the water meter, too short or not the same centerline, should be calibrated in the middle of the pipeline spacing, otherwise it will destroy the water meter pipe or unsuccessful installation.
5.If the cold water table installed in the heating furnace inlet pipe, to avoid heating furnace water and steam flow back to burn the water table.
6.The long-term application of water meter is likely to be due to the pipeline dirt, rust blockage and cause deviation shift. Customers can not destroy the seal on their own, but can go to the water meter measurement and calibration station for repair.
