The main function of the ordinary mechanical water meter is to measure the amount of water flowing through the meter, and convert the water flow into mechanical movement through the internal mechanism and transmission device, and finally show it through the display device. Its accuracy is high, the error is small, generally about plus or minus 5%. Users can know their water consumption according to the reading on the water meter, and arrange the water time and water use accordingly.
2. Display the cumulative water consumption
Ordinary mechanical water meters can also show the cumulative water consumption, the water consumption per unit time will be added up, and returned to the mechanism part, calculate the total water consumption, displayed on the water meter. Users can judge their actual water use by this value and make reasonable savings
