operation and maintenance of the Badger
®
RET™ Recordall
®
Electronic Transmitter. To ensure proper performance, the
instructions given in this manual should be thoroughly under-
stood. Retain the manual in a readily accessible location for
future reference.
Installation, operation and wiring of this unit is fairly simple
and straight forward. This manual is designed so as to provide
you with a step by step guide for this purpose.
Programming the unit is covered later in this manual and
requires a personal computer, a programming interface unit
and special software. The latter two can be purchased from
Badger Meter if required.
The examples provided are only to facilitate an understand-
ing of the functions of the product. Your specific application
will most likely have a different set of values.

Specifications
The Recordall
®
Electronic Transmitter (RET
™
) is designed
for use with all Recordall Disc, Compound and Turbo Series
meters as well as Turbo II meters to provide output compat-
ibility with standard industry instrumentation devices.
The RET is equipped with an LCD digital display that can
be calibrated in either gallons, cubic feet, cubic meters, liters
or imperial gallons. Using a magnet the product allows the
user to toggle between the different displays of totalization,
flow rate, reverse flow, and other meter specific information.
The Recordall Electronic Transmitter is offered in two prod-
uct versions. The standard RET unit comes complete with
both a scaled open collector and unscaled open collector
output signal. The product is also offered with an optional
4 to 20 mA output providing a rate of flow signal.
The Recordall Electronic Transmitter is field programmable
allowing the unit to be calibrated remotely and interchanged
with other Badger Meter products. An internal lithium bat-
tery is used to power the display . The 4 to 20 mA option
requires additional external power for operation.
The RET is designed to be totally submersible. Connec-
tion is made via a waterproof connector cable available in
various lengths.
