Description
The OMNI registers utilize fully solid-state electronics.
The OMNI C

register outputs a programmable (using Sensus Unipro and OMNI
communicators) digital pulse signal suited for interfacing with ACT-PAK instruments
and SCADA systems to achieve a 4 to 20 mA output.
The OMNI R
2
register outputs a programmable (using a Sensus Unipro communicator)
register ID and AMR reading digits.
Features
The OMNI register features programmable totalizer registration, digital pulse signal

only), AMR reading digits, and a resettable test totalizer. Because the
register is hermetically sealed, it is safe for pit environments as well as above ground
settings. The tamper-proof security cover can be positioned in any of 270 degrees of
rotation, with indexing points at each of the 90-degree customary register viewing
positions.
Application
The OMNI register is used where critically accurate totalization of water is imperative.
The OMNI register is designed for a non-explosive atmosphere and can be used in
both above ground and pit settings. In pit settings, OMNI meters can be installed in up
to 4 feet of water depth for continuous submersion and up to 10 feet for intermittent
submersion.
Electrical Connections
The OMNI C

register is standard with both AMR and pulse output wires. The
OMNI R
2
register has standard AMR wires. The pulse wire is 25 feet long; the AMR
wire with touch button is 20 feet long. Splicing of these wires or connecting to these
wires should be performed in accordance with standard practices depending on the
environment of the application. Care must always be taken when connections are
made for meters in high humidity/flooded pit settings. Maximum pulse cable length
should be 1000 feet without a repeater.
The OMNI register can be configured in four arrangements, shown in the following
illustrations.
