Warning:
When the pipe/hose of the LP-Series level transmitter is installed or
removed from the tank the release of flammable vapors will occur.
Take all necessary precaution when installing or removing the level
transmitter due to the release of flammable vapors.

12. Pull the transmitter upward to straighten the flexible hose until
the resistance of the weight, magnet, or hook is felt without
raising the weight or magnet off the floor of the tank. Tighten
the adjustable fitting to hold the transmitter in place. For the
rigid pipe, pull the transmitter upward until the pipe is straight
and the tip of the pipe touches the bottom of the tank. Tighten
the adjustable fitting. Once the fitting is tightened it is no longer
adjustable and cannot be moved.
13. Terminate the field wire cables noting proper wire orientation.
Wiring diagram is shown in Section 13.
Consult Section 5.7 Technical Drawing to reference what the finished
installation should look like.
6.5 Mounting
The method of mounting the transmitter is dependent on the vessel
or tank in which it is being used, and what type of transmitter is being
mounted. For LevelLimit there is only the standard 4“ NPT mount that
allows for the functionality of the HI level switch manual test.
Threaded flange mounting
The LevelLimit
®
transmitter can be mounted directly to the tank or
flange via a NPT threaded fitting, assuming there is a proper threaded
connection available as shown in section 5.7. If the float will not fit
through the flange opening when the flange is removed, there must
be some alternative means to mount the float on the transmitter from
inside the vessel; this may require an access port nearby the entry
point of the transmitter.
