Tightening torque
CAUTION
Table 2-1 shows the tightening torques by bore diameters. To prevent leakage from
the pipe, use the centering fixtures and fix with the prescribed tightening torque. A
leakage would bring about the danger of injury.

Nominal bore diameter of sensor Tightening torque
15 mm 13 - 18 N•m (130 - 180 kgf•cm)*
25 mm 20 - 30 N•m (200 - 300 kgf•cm)*
40 mm, 50 mm, 65 mm, 80 mm 30 - 50 N•m (300 - 500 kgf•cm)*
100 mm 50 - 70 N•m (500 - 700 kgf•cm)*

Flange shape
Referring to Figure 2-7, use a flange that gives a large area of contact with the gasket.

of contact with the
gaskets is small,
there is a risk of
leakage)

~Note • Prior to installing the detector, always do flushing (washing of
pipe) to remove foreign matter inside the pipe. Otherwise, output
fluctuations may result.
• Do not touch the electrodes with your hand, an oily rag or the like.
Otherwise, output fluctuations may result.
• Make the flow direction mark of the detector agree with the direction
of the fluid flow. In case of disagreement, no output will be delivered.
