Electronic level sensor

LR8009

19

For pipes with ¾" NPT process connection:
apply a suitable sealing material (e.g. Teflon tape).

u

Screw the device with the coaxial pipe into the tank and tighten it.

5.7 Alignment of the sensor housing

After installation, the sensor housing can be aligned. It can be rotated without restriction. Even if
rotated several times there is no risk of damage to the device.
