When a flow meter does not read properly, what is the first thing you should check?

• A. Power to a circuit
• B. Water pressure
• C. Calibration of the meter
• D. Connections to the transmitter

Answer: (A)

When troubleshooting a flow meter that is not reading properly, the first thing to check is the power to the circuit. Flow meters are electronic devices that rely on a power source to function correctly. If the flow meter is not receiving sufficient power, it may not operate at all or may produce erratic readings. Ensuring that there is power to the circuit is a fundamental step in diagnosing the issue, as without power, no further checks can effectively determine the cause of the malfunction. After confirming that power is present, other factors such as water pressure, calibration, and connections to the transmitter can then be investigated. However, if the meter isn't powered, those subsequent checks won't yield any relevant information because the device simply won't be operational in the first place.
