Aug 28, 2024 · How do Residential Water Meters Work? Residential water meters operate on a simple principle known as positive displacement. As water flows through the meter, it passes through a chamber containing one or more rotating discs or pistons.
Sep 24, 2018 · The meter has an impeller, which is a rotating device that rotates when water flows through it. The rotation is measured, but the water meter has to be full of water to get a correct reading. An ultrasonic meter (velocity meter) uses electronic sensors to measure the water velocity.

Water meters measure the volume of water used by residential and commercial building units that are supplied with water by a public water supply system. They are also used to determine flow through a particular portion of the system.
Mar 8, 2022 · There are three important components that must be considered for a water service entry line--the water meter, a local/remote reading device and a backflow prevention device.
How a Water Meter Works. Learn how water is measured as it enters your home or building. When water comes into your home or building, it enters through a water lateral and then goes through the water meter. All of the water that enters the building is measured.
FLOW RATE INDICATOR: Not all meters have a flow rate indicator. Some meters only display the volume of water, while others display both the flow rate and the volume. A meter may have a sweep hand. This is similar to the minute hand of a clock.
Principle of operation: Proportional meters have an orifice which restricts flow and forces a portion of flow through the meter. Total flow is determined by reading the meter and multiplying the reading by a factor. Proportional Water Meters.
