4. Mounting
•
Minimum nozzle diameter should be 2” from the probe at initial installation.
•
Probes should not contact metallic tank walls, obstructions or structures.
•
If using cable probes, take into account the possibility of cable sway encroaching clearance requirements of
agitators and augers. If this possibility occurs, secure a ring or mounting connection to the cable weight and
to the vessel oor.
Note: The Tek-Flex 4100A will come factory set for mounting to a metallic ange or tting unless otherwise
instructed at time of order.

Transmitters with threaded process connectors can be screwed to tanks or nozzles with threaded bosses.
Tek-Flex 4100A transmitter can be successfully installed in a new or existing bypass pipe, bridle, or a side
pipe as shown in the gure. This type of installation is often simple and allows the addition of radar level
measurement to an otherwise busy installation.
