Flow Measurement

Measurement mode

The mode in which the flow is detected and the flow indicator flashes, and analogue output is operating.



: Green: Flashes once.

PF3W5□-□-1 (Analogue 1 to 5 V type: Without temperature sensor)

Flashes twice.

PF3W5□-□-2 (Analogue 4 to 20 mA type: Without temperature sensor)

Flashes three times.

PF3W5□-□-1T (Analogue 1 to 5 V type: With temperature sensor)

The power LED (Green) turns on and the flow rate indicator flashes according to the flow rate.
