Turbine flow meters provide what kind of signal?

Turbine flow meters provide what kind of signal?

• A. Analog voltage output
• B. Pulse output only
• C. Frequency or pulse output signal
• D. Digital temperature reading

Answer: (C)

Turbine flow meters turn fluid flow into rotor rotations, and each rotation creates a pulse. The rate of those pulses—the frequency—matches how fast the rotor turns, which is proportional to the flow rate. The meter outputs this as a pulse train or a frequency signal, which digital systems can count or measure to determine flow. It isn’t an analog voltage signal or a temperature reading, so the correct description is a frequency or pulse output signal.
