Horizontal Mounting

When tightened securely, the sensor

cavity must be positioned vertically for

optimum drainage when process liquid

level drops below the sensor cavity.

An alignment mark X stamped on a

wrench flat (or on the dry face of a

flange below the housing) shows

sensor cavity orientation.

Optimum drainage occurs when the X

mark is located at 6 or 12 o’clock.

Level is detected when the sensor

cavity is filled with process liquid.

The sensor must project through a tank

fitting so that the sensor cavity is at least

1” beyond the inner wall of the tank.
