Most residential and commercial buildings use the water meter to measure the volume of water supplied by the public water supply system. You can determine the water flow with a particular portion of the system. When the water passes through the meter, it can measure the amount of water passed through it if you find any water leaks to save the water, which can lower the water billing.
