Flow Sensor; Instructions For Use - Open System CPFM-Tester User Manual

"OUT" - output, respectively, of the measured flow;
"220" - for connecting the main power ~ 220 V.
The "NET" connector is structurally made in one housing with a fuse.
In the updated version of the device, near the pipe outlets, there are two
connectors (2 contact) for controlling the valves. The control voltage of the valves is
+ 24V and is applied at the start of the measurement (blinking of the button).
Version 1.06 (software) adds support for valve control.
To measure the flow, the device uses a flow sensor.
Thanks to friction-free fluid measurement technology, the sensor provides
superior linearity over the entire measurement range. Sensor specifications are listed
below:
