SOR RF Continuous Level Transmitter - Manual

Probe Installation
SORtrax is a 4-20 mA continuous level transmitter. It produces a
4-20mA current superimposed on the 12-55 VDC loop supply lines. The
4-20mA current is proportional to the level sensed by the instrument.
SORtrax detects level based on process admittance. Bench or field
calibration is easily accomplished. Coarse and fine adjustments are
provided to allow the user full control over the zero and span settings,
and to insure the most accurate operation possible. Recalibration is
needed each time the content of the process changes, due to the
different dielectric constant of each material.

Probes are mounted vertically from the top of a vessel. The probe must
be electrically isolated from the vessel; make no connection between the
probe and the vessel other than the process connection and (if applicable) the threaded
weight at the probe tip.
Do not weld any part of this instrument.
Make sure that the sensor can be fully inserted and tightened without interference from
obstructions inside the tank or vessel. The probe should be mounted away from inlet
fill paths. Spray from a fill path may cause false level indications.
