4. Piping Method
Then, after reviewing the precautions, connect the FP-4135 On-Board Volumetric Flow Detector.
z
Do not remove the line filter from the detector.
The line filter is built into the FP-4135 On-Board Volumetric Flow Detector. So, it should not be removed from the detector.
The built-in line filter in the detector is designed to remove large debris in the piping connection, so use the other line
filters upstream of the liquid inlet of the detector.
z
Check the IN and OUT of the detector.
The detector has an inlet (IN) and an outlet (OUT) for the liquid. Recheck the inlet and the outlet when piping.

Recommendations on bypass valve installation
Installing a bypass valve in the piping as follows is recommended to maintain the measured system such as an engine,
release air pockets out of the piping, or to repair a detector malfunction.

z
Make sure the power is disconnected (OFF) before starting piping.
Make sure the power of the Ono Sokki DF-2200 On-Board Flow Meter or the FM Series Digital Flowmeter are
disconnected (OFF).
To switch the power on/off, use the power switch of the Ono Sokki DF-2200 On-Board Flow Meter or the FM Series
Digital Flowmeter after connecting the FP-4135 On-Board Volumetric Flow Detector to the Ono Sokki DF-2200 On-
Board Flow Meter or the FM Series Digital Flowmeter with the flow signal cable, or use the power switch on the side of
Ono Sokki DF-2200 On-Board Flow Meter or the FM Series Digital Flowmeter.
z
Pay attention to how to wind the seal material.
Follow the instructions below to wind a Teflon seal tape on screws, for example when changing the joints.
• A seal tape should be wound 2 to 2.5 times to a screw with the last 1 to 2 threads of a screw not tightened. The
number of times you need to wind may differ depend on the thickness of the seal tape.
• When using liquid seal material, be careful not to leak the liquid material to piping.
• The standard tightening torque for the joint R1/4 is 12 to 14 N •m.
