2. Water metering - Wikipedia

   en.wikipedia.org/wiki/Water_metering

   A velocity-type meter measures the velocity of flow through a meter of known internal capacity. The speed of the flow can then be converted into a volume of flow to determine the usage. There are several types of meters that measure water flow velocity, including jet meters (single-jet and multi-jet), turbine meters, propeller meters and mag ...

3. Flow measurement - Wikipedia

   en.wikipedia.org/wiki/Flow_measurement

   Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...

5. Current meter - Wikipedia

   en.wikipedia.org/wiki/Current_meter

   An instrument of this type is the Acoustic Doppler current profiler (ADCP), which measures the water current velocities over a depth range using the Doppler effect of sound waves scattered back from particles within the water column. The ADCPs use the traveling time of the sound to determine the position of the moving particles.

6. Flow computer - Wikipedia

   en.wikipedia.org/wiki/Flow_computer

   Rotary gas meter with (T) pulse emitter (P) pressure transducer (C) flow computer. A flow computer is an electronic computer which implements algorithms using the analog and digital signals received from flow meters, temperature, pressure and density transmitters to which it is connected into volumes at base conditions. They are used for ...

7. Automatic meter reading - Wikipedia

   en.wikipedia.org/wiki/Automatic_meter_reading

   The meter communicates to its collection point using 900 MHz mesh network topology. Automatic meter reading (AMR) is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and ...
