SOR Submersible Hydrostatic Level Transmitter - Manual (Page 3)

Form 948 (10.09) ©2009 SOR Inc. 3/8
The Series 510 is designed to be self-supporting in any plane when rigidly mounted by the
pressure port (1/4” NPT process connection) under the removable nose cone. For rigid
installation, thread the transmitter in place using the wrench flats provided.
Both models are designed to be supported by the shielded electrical cable when suspension
mounted. A stainless steel strain wire is incorporated in the cable for attachment to a rigid
structure. If a rigid structure is not available, the SOR cable clamp accessory (P/N 9137-104,
ordered separately) provides a means for suspension without damaging the cable.
When mounting the transmitter, care must be taken to prevent the cable bending through a radius
smaller than 2 inches. Failure to observe this precaution may result in damage to the cable internal
vent tube. This may give incorrect readings from the transmitter. Care must be taken to prevent
water entering or foreign objects block ing the vent tube, either of which may result in a fault
condition. Faults of this nature are not covered by the warranty.
Avoid mounting the transmitter near a heat source which is liable to overheat the instrument
or cause a tempera ture gradient across it. If this is unavoidable, introduce a heat shield to deflect
radiated heat and thus maintain the transmitter at a uniform temperature within the specified limits.
Although the operating temperature of the transmitter extends to below 32°F, fluids must not be
allowed to freeze in the pressure port. Failure will occur due to the expansion of the frozen fluid in
the contained volume of the pressure port causing gross overpressurization. A failure of this nature
is not covered by warranty.
The transmitter should not be used as a step!
SOR 510 submersible products should not be used in liquids known to have
or possibly contain chemical compounds that react with butyl rubber or
stainless steel.
Installation
Before installing the transmitter, verify that the range stated on the transmitter label is
suitable for the level (pressure) to be measured.
