Neptune’s UME Design
Neptune’s UME allows for the quickest, most efficient way to service
your large meter. It is available for the TRU/FLO, HP Turbine,
HP PROTECTUS III, and Fire Hydrant meters. The UME assembly
consists of the meter’s cover with all of the measuring components
either contained within the cover or attached to it.
• For a TRU/FLO meter, this includes the bronze cover with the two
registers, the T-10 chamber, and the turbine measuring assembly.
For the HP Turbine, HP PROTECTUS III, and Fire Hydrant, this
includes the register, bronze cover, and the turbine measuring assembly.

When a new UME is ordered from Neptune:
• The UME comes with two new registers attached.
• The UME has completed an accuracy test and receives a new test
ticket ensuring its accuracy.
Since the bronze body is warrantied for life, the UME can be easily
replaced by removing the bolts, separating the cover from the maincase,
removing the old UME, and dropping in the new UME. In fact, after this
maintenance is performed, you have the equivalent of a brand new
meter.
Performing Maintenance on the Meter
This section provides information on maintaining a meter.
This includes removing and reinstalling the cover assembly.
A precalibrated UME can be ordered from Neptune.
Always wear protective eye wear when working with any
product.
