SOR Submersible Hydrostatic Level Transmitter User Manual

Submersible Level Transmitters

A)

General Instructions

The Series 510 Submersible Level Transmitters are solid state
instruments designed for direct submergence into many types
of liquid for quick, accurate and reliable level measurement.
The transmitter indicates the level of the liquid by continuously
measuring hydrostatic head pres sure using a high performance
ceramic sensor. Electrical connection is made via a 20 gauge
shielded waterproof cable which is vented at the surface to
reference atmos pheric pressure.

Once the transmitter is installed and wired into a control or
display loop, it is ready for use. Before applying power, check
that the supply polarity and excitation volt age is correct.

Series 510

Do not twist the wires during installation or servicing
the instrument as it may break the integrity of the
seal between the wires and the transmitter. Failure of
this nature is not covered by warranty.

NOTE: If you suspect that a product is defective, contact the factory or the

Calibration

The transmitter is supplied factory calibrated and during normal use should not require
recalibration. If it is desired to verify calibration prior to installa tion of Series 510LT,
remove the nose cone and attach to a pressure source capable of adjustment
throughout specified range. If outputs are not within limits at factory calibration
conditions, 77°F (25°C), the device should be returned to the factory.

Units in hazardous locations - prior to removal from service, make sure
that the work area is declassi ed.m Failure to do so could result in severe
personal injury or substantial property damage.

Installation

Before installing the transmitter, verify that the range stated on the transmitter label is
suitable for the level (pressure) to be measured.

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.

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.

The transmitter should not be used as a step!

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.
