Electromagnetic meters uses electrical voltage to figure out water usage. Magnetic fields and electrodes surround part of the pipe and when water comes through the pipeline, it creates an electric voltage. The electrodes will detect how much water is being generated and measure the voltage.
How is a smart water meter powered?
Thames Water’s smart meters are low powered using just 25mW power emission. Mobile phones use 80 times more (2,000mW) and Wi-Fi four times higher (100mW).
Do smart water meters have a battery?

Are water meters powered?
To extend operating life, all leading meter transmitter units (MTUs) are powered by long-life bobbin-type lithium thionyl chloride (LiSOCl2) cells that feature the highest capacity, highest energy density, the widest possible temperature range, and unrivaled battery life.
How do water meters transmit readings?
Meters transmit a read using a radio frequency (RF) device that attaches to the meter. Meters may also be read by visually inspecting the face of the meter or by touchpad. As meters age, they may slow down and under- report the amount of water delivered. Most meters are replaced depending on size and installation date.

How are power meters read?
To determine your correct meter reading, simply read the dials in order from right to left. As you read each dial, write down the number. In most cases, the pointer will be between two numbers on the dial. THE CORRECT NUMBER IS THE LOWER OF THE TWO, EXCEPT WHEN BETWEEN THE 0 AND 9, IN THAT CASE YOU WOULD READ THE 9.
Do smart meters need power supply?
Smart meters are a next generation meter for both gas and electricity.If you have a smart meter you don’t need to rely on estimated energy bills or provide your own regular readings. Smart meters also come with an in-home display.
Do smart meters need mains power?
Energy Customers
