Mounting position
When finding an appropriate location on the tank for the transmitter, the conditions of the
tank must be carefully considered.
Consider the following guidelines when mounting the transmitter:
•
For optimal performance, the transmitter should be installed in locations with a clear
and unobstructed view of the product surface.
•
The transmitter should be mounted with as few internal structures as possible within
the signal beam.
•
Do not install the transmitter in the center of the tank.
•
Do not mount close to or above the inlet stream.
•
Do not mount the transmitter on a manway cover.
•
Do not position the transmitter directly over a side manway door.
•
Multiple Rosemount 3408 transmitters can be used in the same tank without
interfering with each other.
