CLAIMS
What is claimed is:

1. A self-powered in-pipe fluid meter to be mounted inside of a pipe carrying a fluid therein, comprising:
at least one sensing unit capable of measuring one or more parameters of the fluid inside of the pipe;
a telemetric data transmission unit capable of telemetrically transmitting data including a measured fluid parameter to a host terminal and/or another fluid meter; and at least one fluid-driven power source unit capable of generating power from the fluid flow within the pipe and supplying power to the sensing unit and/or the transmission unit.

2. The fluid meter according to claim 1, wherein:
the transmission unit has a two-way telemetry function so that it is further capable of receiving data from the host terminal and/or another fluid meter.

3. The fluid meter according to claim 1 or 2, further comprising:
at least one fluid sampling unit capable of extracting a sample of the fluid inside the pipe and exposing the sample to said at least one sensing unit.

4. The fluid meter according to any of claims 1 to 3, further comprising:
at least one signal conditioning unit capable of processing the fluid parameters measured by said at least one sensing unit.

5. The fluid meter according to any of claims 1 to 4, further comprising a control unit capable of:
controlling power supply from the power source unit to one or more of the other units; and/or storing data received from said sensing unit and/or at least one signal conditioning unit and/or the host terminal; and/or
processing data received from said host terminal and/or another fluid meter.

6. The fluid meter according to any of claims 1 to 5, said fluid-driven power source unit comprising a power generator and a battery storage.

7. The fluid meter according to any of claims 1 to 6, said transmission unit comprising an acoustic-wave transmission device capable of transmitting data via an acoustic wave through the fluid within the pipe.

8. The use of the fluid meter according to any of claims 1-7 as a water quality meter.

9. A fluid transmission piping network comprising a plurality of self-powered in-pipe fluid meters according to any one of claims 1-7 respectively mounted inside of a pipe of the piping network.

10. The fluid transmission piping network according to claim 9, each fluid meter being capable of communicating with an adjacent fluid meter via the respective telemetric data transmission unit.
