Yokogawa ISC40 Inductive Conductivity Sensor - Manual (Page 15)

The sensor cable and mounting thread
are pulled through the hole of the flange,
and the sensor is sealed from the process
by tightening the mounting nut. Turning
of the sensor by the torque forces can be
avoided by using a wrench on the flats
on top of the sensor (see fig. 5). Sensor
is installed correctly if the flats are aligned
perpendicular on the process flow.
