Components and functionality of a manual water meter test bench

Water meter test bench can help to approve the accuracy of water meters.How is the water meter test bench composed? what are its functions?

1.Flow Control System: The bench is equipped with a flow control system that regulates the flow rate of water through the test setup. This system typically includes valves, flow meters, and pressure regulators to control the water flow accurately.

2. Water Supply: A water supply source, such as a reservoir or a dedicated water line, is connected to the test bench. This source provides water for testing the meters.

3. Meter Under Test (MUT): The water meter being tested is connected to the test bench. The bench provides the necessary connections, such as inlet and outlet pipes, to attach the meter securely.

4. Reference Meter: A reference meter with a known accuracy is connected in parallel with the meter under test. The reference meter serves as a benchmark for evaluating the accuracy of the tested meter.

5. Measurement Instruments: The test bench includes measuring instruments to monitor various parameters. These instruments may include pressure gauges, temperature sensors, flow meters, and data acquisition systems to capture relevant data during the testing process.

6. Control Panel: The control panel allows the operator to set and adjust the flow rate, pressure, and other parameters during the test. It may also display real-time measurements and provide controls for data acquisition.

7. Test Procedures: The test bench follows specific test procedures to evaluate the performance of the water meter. These procedures typically involve measuring the accuracy at different flow rates, checking the repeatability, and verifying the meter's response to varying flow conditions.

8. Calibration and Adjustment: If discrepancies are found between the tested meter and the reference meter, the bench allows for calibration and adjustment of the meter under test. This may involve modifying the meter's internal components or making calibration adjustments to ensure accurate readings.
