• Provide a straight pipe section in upstream side and downstream side of the
installation location.
Refer to the drawings below for the length of upstream pipe section. D indicates
the connecting port size. Secure the length of more than 5D for the downstream
pipe section.
• If the oil, water or dust is contained in a fluid, install a device to remove them.
If the oil, water or dust is contained in a fluid, they might cause measurement
error or faulty operation.
Note
• Remove the water using a dryer so that it does not cause dew condensation in
the pipe.
• Use a dust-eliminating filter of less than 1µm mesh.
• Use an oil-eliminating mist separator with the eliminating capability of resid-
ual oil density less than 0.01mg/m
