Mounting
The figure below shows how to actually mount the flowmeter. Before
installing the flowmeter, be sure to flush the piping to remove any
foreign objects inside.
Handling Precautions
Do not flush the piping with the flowmeter attached. Doing so might
cause foreign objects to enter the flowmeter and cause error.

Tighten according to the torque in the following table:
Aperture/Flange Rating
Torque (N•m)
40mm JIS10K
22 to 32
50mm JIS10K
24 to 34
Handling Precautions
• Tighten bolts so that they are uniformly tight. If leakage does not
stop after tightening bolts, gradually tighten the bolts more a
little at a time.
• Tighten bolts within the specified tightening torque. Otherwise,
the bolts may be damaged.
• Do not mount as shown in the following figure. Doing so might
cause leakage.
