Foreword
Product overview
The 9700 Series range of tank level transmitters
from Delta Mobrey, is a loop powered level transmitter.
It provides an accurate level measurement solution
where in-tank problems such as foaming, vapor layers,
and temperature gradients makes the use of other
instrumentation difficult.
The series comprises 3 different models for
measurement inside the tank and one for
measurement outside the tank with different
connections available, to meet the requirements of the
installation:
Models:
9710, 9720, 9780 for installation INSIDE the tank
Models:
9790 for installation OUTSIDE the tank
The transmitter is designed to withstand the harshest
of environments.
Its rugged, flush ceramic sensor is inherently capable
of withstanding attack from most chemicals.

Warning: Units must be selected and installed by
suitably
trained
and
accordance with appropriate codes of practice so
that the possibility of failure resulting in injury or
damage caused by misuse or misapplication is
avoided.
Warning: Before installation check that the
characteristics of the chemical seal comply with
process and plant requirements
Warning: The user should ensure the equipment is
suitable for use in the application with aggressive
substances.
Warning: The users attention is drawn to the fact
that, when the unit is 'live' with respect to electrical
or pressure supplies, a hazard may exist if the unit
is opened or dismantled.
Warning: Do not try to disassemble the cable nor
the pole from the transmitter
Warning: Use appropriate tools for the installation
or the device.
Warning: Do not hang the instrument from the
cable!
