The absolute minimum is typically ten times the amount of inside diameter of the straight pipe before the meter and five times the amount after the meter. FPW Manual Page 4 (total 18) COMAC CAL s.r.o. - Page 5 U, by which means permanent submersion of the lower part with the meter is ensured. For the same reason, we recommend you to place the meter on the upstream side of the ascending piping. FPW Manual Page 5 (total 18) COMAC CAL s.r.o.

Page 14: Pulse Output (Fpw 05 Only)
Pulse output (FPW 05 only) In case of FPW 05 flow meters, it is only the pulse output dependent on the flow velocity within the range of 0.3-6m/sec. User wiring Internal wiring Wiring example: Pulse output or make/break contact (FPW 10 and FPW 20 only) -
Page 15: 4-20Ma Output (Fpw 20 Only)
4-20mA output (FPW 20 only) The manufacturer delivers the meter with output set to 4-20mA in such a manner that at zero flow velocity of the medium, the output value is 4mA and at 6m/sec it is 20mA. The dependence of flow on velocity is linear. -
Page 16: Customization And Control Of Fpw Meter
Customization and control of FPW meter In case of FPW 05 version, it is not possible to set or change its parameters that are set by the manufacturer. This version does not have a button. Setting by button is only available in FPW 10 and FPW 20 versions. -
