1 OMNI™ meter overview
OMNI water meters feature unrestricted sustained flow rates within their continuous
operating range. The OMNI meter's Floating Ball Technology (FBT) measuring element
operates virtually without friction or wear.
Each OMNI meter consists of two basic assemblies: the maincase and the measuring
chamber. The measuring chamber assembly includes the "floating ball" impeller and an
all electronic programmable register. The OMNI+ electronic register is a hermetically
sealed register with an electronic pickup containing no mechanical gearing.
OMNI™+ register
The OMNI+ register features a programmable totalizer registration, an optional digital
pulse signal (C2/F2/T2 only), AMR reading digits, and a resettable test totalizer.
The OMNI+ register is designed for a non-explosive atmosphere. 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. The
OMNI+ register is IP68 rated to 2 m.
Alarms
The OMNI+ alarms alert you to a myriad of conditions including reverse flow, leak, high
flow, and low battery life.
You can view alarms and event on the LCD display. Alarm state is logged hourly. You
can use field tools to retrieve the alarm log. In an AMI fixed-base system, alarms and
events are transmitted over FlexNet and you can user FieldLogic™ or Device Manager
to troubleshoot and clear the alarms.
Data logging
The OMNI+ logs 180 days of hourly data.
Data is retrieved directly from the meter and not through the SmartPoint due to battery
impact and time required to retrieve.
