Internal Circuits and Wiring Examples

2-Colour Display Digital Flow Switch

Series PFM7

Specifications

Note 1) When the minimum unit setting 0.01 l/min is selected for 10 l/min type, the indication upper limit will be [9.99 l/min].

When the minimum unit setting 0.1 l/min is selected for 100 l/min type, the indication upper limit will be [99.9 l/min].

Note 2) User can select between 0.01 l/min and 0.1 l/min for the PFM710, and between 0.1 l/min and 1 l/min for the PFM711 respectively.

If the indication unit is selected to “CFM”, the minimum unit setting cannot be changed.

At the time of shipment from the factory, the minimum unit setting is set to 0.1

l/min for the PFM710 and 1 l/min for the PFM711 respectively.

Note 3) Set to “ANR” at the time of shipment from the factory.

“ANR” is used for standard conditions: 20

°C, 1 atm and 65%R.H.

“Nl/min” is used for normal conditions: 0°C and 1 atm.

When equipped with a unit switching function. (The SI unit

(l/min or l) is fixed for types with no unit switching function.)

Note 4) Cleared when the power supply is turned off. Hold function can be selected. (Interval of 2 min or 5 min can be selected).

If the 5 min interval is selected, the life of the memory element (electronic part) is limited to 1 million cycles. (If energised for 24 hours, life is calculated as 5 min x 1 million

= 5 million min = 9.5 years). Therefore, if using the hold function, calculate the memory life for your operating conditions,

and use within this life.

Note 5) Set to 1.5 s (90%), can be changed to 100 ms.

Note 6) Set to hystresis mode at the time of shipment from the factory. Can be changed to window comparator mode using push-buttons.
