Water meter is one of the "three meters for civil use". It is an instrument for water trade settlement. It has a large volume and a wide range. Water meter factories are closely related to industrial production and people's lives. Although there are some problems in the product quality of the water meter industry, water meter products have been developing towards the good side. It is manifested in the following five aspects:
I. Water meters with high measurement levels, convenient reading, and more hygienic materials: high measurement level indicates that the water meter has strong working performance under small flow rates.
II. Water meters that combine remote reading and computer property management: water meters that match remote water meters, centralized reading systems, and secondary meters are promising. This method improves the reading method of water meters and increases the It improves the degree of informatization, digitization, and automation, and reduces the disturbance and security concerns of users who use water meters. The use of remote water meters and meter reading systems is an ideal way to solve water meter reading and water fee settlement, but the standardization and standardization of meter reading systems and the traceability of system parameter changes have also attracted the attention of all parties.
III. Prepaid water meters: suitable for the management system under the condition of "pay first and then use water". In some areas, it is difficult to collect water fees, and the phenomenon of water fee arrears is serious. The use of prepaid water meters has completely changed the way of meter reading and settlement of water consumption, so it is welcomed by water companies and property management companies. Typical products include IC card water meters, TM card water meters, code exchange prepaid water meters, etc.
IV. Water meters with high sensitivity: Water meters with high sensitivity and high measurement levels refer to water meters that use a certain mechanism to increase the initial flow of the water meter without changing the normal measurement characteristics of the water meter. The commercial name is "water-saving type" Water Meter", "Automatic Compensation Water Meter", and "Drip Metering Water Meter".
V. Anti-backflow water meter and two-way metering water meter: The anti-backflow water meter prevents the possibility of cheating by artificially installing the water meter by installing a one-way valve at the entrance of the meter or sealing the connecting pipe of the water meter with the water pipe. The function of the two-way metering water meter is that when the flow is reversed, the counting mechanism of the water meter is still accumulative and meets the requirements of metering accuracy.
