Prepaid water meter
Prepaid water meters are suitable for the management system under the principle of "pay first and then use water". In some areas of our country, it is difficult to collect water charges, and the phenomenon of unpaid water charges is serious. The use of prepaid water meters has completely changed the settlement method of meter reading water, avoided the intensification of contradictions and improved the technical content of water meter products.
Some water companies and property management companies welcome this product. Prepaid water meters can collect water charges timely and reasonably, reduce the loss of water charges, reduce labor intensity, and avoid the inconvenience and insecurity caused by meter reading activities. Typical products include IC card water meter (plug-in or induction type), TM card water meter, code exchange prepaid water meter and so on.
Anti-reflux water meter
Household water meters are generally single-flow meters, and most of them can move and reduce the cumulative number when they flow reversely (also known as countercurrent or countercurrent). The existing water meter lead sealing mechanism does not have the function of preventing the water meter from being reversed, so it may cause metering disputes and cheating.
The backflow prevention water meter seals the connecting pipe between the water meter and the water pipe by installing a one-way valve at the entrance of the water meter, which eliminates the possibility of cheating by artificial backflow water meter. The function of the two-way metering water meter is that the counting mechanism of the water meter is still cumulative when it flows in the reverse direction, and meets the requirements of metering accuracy.
Note: There is no detailed regulation on backflow prevention water meter or bidirectional metering water meter in the current national standard, which only requires that the water meter can "withstand accidental backflow and display backflow".
