Flow measurement Wikipedia
Sonar flow meters have the capacity of measuring the velocity of liquids or gases non intrusively within the pipe and then leverage this velocity measurement into a flow rate by using the cross sectional area of the pipe and the line pressure and temperature. The principle behind this flow measurement is the use of underwater acoustics.
Two Phase Flow meter Chemical process engineering Eng Tips
Density is also measured by the meter independantly and used to divide the mass flow to produce the volumetric flow which is correct for the mixture. The question of inaccuracy creeps in where zero correction for no flow is made as the tube(s) may contain a nonrepresentative gas/liquid mixture.

Basic Principles of a Water Meter
Types of Water Meters. The water meters are classified into two basic types as follows: Positive Displacement Meters. With this type of meter, a known quantity of liquid within a small unit moves with the flow of water. They operate by repeatedly filling and emptying the unit. The flow rate of water is calculated based on the number of times the unit is filled and emptied.
NUFLO Liquid Turbine Meters
NUFLO LT standard piping liquid turbine flowmeters indicate flow rate and measure total throughput of a liquid line.

10 ways to hack your water utility The Water Nexus Blog
Your water utility uses a wastewater average because they can’t measure the actual amount of wastewater discharged from your home. Potable water coming into your house is measured with a water meter since the water is pressurized, but wastewater flows out of your home by gravity. It is not easy to measure gravity water flow through a pipe.

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.

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.
Measuring flow rate (Doppler device) Physics Forums
As long as the meter is in the flow, yes. If I understand that correctly, water can still flow out of the pipe, it's just that the exit is partially blocked. The water will flow faster through the smaller opening, but the volume flow rate will be the same.

Velocity meters include turbine meters, venturi meters, orifice meters, ultrasonic meters, magnetic meters,
Differential Pressure Flowmeter Technology Flowmeters
Differential pressure flowmeters inferentially measure the flow of liquids, gases and vapor, such as water, cryogenic liquids, chemicals, air, industrial gases, and steam. Be careful using differential pressure flowmeters for fluids with high viscosity, such as some hydrocarbons and foods, because their accuracy can be degraded when Reynolds number is low.
Flow Measurement in Pipes and Ducts Engineering
The other major category of flow is open channel flow, which is the flow of a liquid with a free surface open to atmospheric pressure. Measurement of the flow rate of a fluid flowing under pressure, is carried out for a variety of purposes, such as billing for water supply to homes or businesses or, for monitoring or process control of a wide variety of industrial processes, which involve flowing fluids.
Liquid, Water, Air, Gas Flow Meters & Switches Rheotherm
Flow switches differ from conventional gas or liquid thermal flow meters by changing the state of an output relay once certain flow parameters are met.
