Major Function: 1. Grade the water price: The water meter charges for water consumption in accordance with the pre-set graded water price. 2. Remnant value alarm function: The valve will close one time if the remnant value reaches the pre-set alarm value.  Users can insert the card to open the valve till the pre-set value is used up. 3. Value return:Users can process value recovery, or card return procedures. 4. Digital display: Users can read total value, remnant value, total water consumption, valve situation etc. on the LCD display. 5. Anti-magnet: The water meter valve will close if interfered by strong magnet, which will lead to measuring failure. The valve will automatically open after the magnet is eliminated. 6. Voltage monitoring: The valve will close after alarming of the low battery. It reminds users to change a new battery and will keep the information in the water meter.

Features: 1. Material: The main body of the water meter is made of brass. 2. Measuring Mechanism: The measuring mechanism consists of a rotating impeller or turbine that is driven by the water flow. The rotation of the impeller is directly proportional to the volume of water passing through the meter. 3. Ease of Installation: Single jet water meters are relatively easy to install due to their compact size and straightforward design. They can be installed horizontally or vertically, depending on the specific model and installation guidelines.

Features: Water meter check valves have several key features that make them effective and reliable for their intended applications: 1. One-Way Flow; 2. Spring-Loaded Mechanism; 3. Low Pressure Loss; 4. Compact Design; 5. Corrosion Resistance; 6. Easy Maintenance; 7. Standards Compliance;
