Recommended Mounting
Position
Figure 3-7. Mounting Position
When finding an appropriate mounting position for the transmitter the
conditions of the tank must be carefully considered. The transmitter should be
mounted so that the influence of disturbing objects is reduced to a minimum.
In case of turbulence the probe may need to be anchored to the bottom. See
"Mechanical Installation" on page 3-13 for more information.
Inlet pipe
The following guidelines should be considered when mounting the transmitter:
• Do not mount close to inlet pipes.
• Do not mount close to agitators. If the probe can move to within 30 cm
away from an agitator a probe tie-down is recommended.
• If the probe tends to sway due to turbulent conditions in the tank, the
probe should be anchored to the tank bottom.
• Avoid mounting close to heating coils.
• Make sure that the nozzle does not extend into the tank.
• Make sure that the probe does not come into contact with the nozzle or
other objects in the tank.
• Position the probe such that it is subject to a minimum of lateral force.
NOTE!
Violent fluid movements causing high sideway forces may break rigid probes.
