construction" section.
5.1.2 General installation instructions
• Devices with a G 1 1/2 thread:
When screwing the device into the tank, the flat seal has to be positioned on the sealing
surface of the process connection. To avoid additional strain on the process membrane, the
thread should never be sealed with hemp or similar materials.
• Devices with NPT threads:
• Wrap Teflon tape around the thread to seal it.
• Tighten the device at the hexagonal bolt only. Do not turn at the housing.
• Do not overtighten the thread when screwing. Max. tightening torque:
20 to 30 Nm (14.75 to 22.13 lbf ft)
5.2 Mounting the device
• Due to the orientation of the Deltapilot S, a zero point shift may occur, i.e. when the vessel
is empty, the measured value does not display zero. You can correct this zero point shift
either directly on the device via the  button or via remote operation.
• To ensure optimum readability of the local display, it is possible to rotate the housing by up
to 380°.
• The local display can be rotated in 90° stages.
• Hauser offers a mounting bracket for installation on pipes or walls.

NOTICE
Damage to the device!
If a heated device is cooled during a cleaning process (e.g. by cold water), a vacuum develops
for a short time and, as a result, moisture can enter the sensor through the pressure
compensation element (1).
‣
Mount the device with the pressure compensation element (1) pointing diagonally
downwards or to the side as much possible.
