The flow transmitter measures the differential pressure created by the orifice plate in the flow stream.
How to Check if Your Water Meter is Faulty
If you check the measurement of water with your water meter and the numbers don't add up, you have yourself a faulty meter and that needs to be replaced as soon as possible. If you use city water, you can call out a representative from your water provider to give you a new one, but that is a lot like pulling teeth.

Detecting water flow in pipe with Ultrasonic Motion Detector
You could just have a little propellor in the pipe that connects to a small generator. When water flows a small amount of electricity will be generated which you can detect with a voltmeter. If there is no water flowing, the propellor won't turn and therefore neither will the shaft of the generator. Thus, you have no electricity.
