Neptune’s T-10 Features
Nutating Disc Measuring Chamber
• Positive displacement = positive
revenue stream ($$$)
• Widest effective flow range for
maximum revenue
• Less wear equals better sustained
long-term accuracy
• Quieter operation on inside set meters
• Allows debris to pass more freely
• Proprietary polymer materials
maximize long term accuracy
• Lower head loss equals better
accuracy and line pressure
Nutating Disc Provides Better Long Term Accuracy
Positive Displacement Meter Types Neptune
• Trident Style 1&2 (Long neck) 1892-1960

Compound Meters - How Do They Work?
Two meters in one maincase

• Turbine for moderate to high
flows
Hydraulic valve
• To transition flows from PD
meter to turbine and vice-versa
Two registers
• Register for the PD meter and a
register for the turbine meter
Automatic Throttling Valve
• To protect the PD meter from
pre-mature wear
Test Ports
• Facilitates testing

Main Case
TRU/FLO Compound
At low flow, the main valve prevents water from flowing through
the Turbine element.
All water is diverted through the cover, into the T-10 chamber
and out the throttle tube.
Low Flow
The actuation of the valve piston and the subsequent reduction
of flow through the T-10 chamber “shunts” a large volume of
water through the turbine measuring element forcing the main
valve open. Both the turbine and the T-10 are operating.
Crossover
At intermediate and high flow rates, the main valve is fully open and
the majority of the water flows through the turbine. Water continues to
flow through the T-10 at a greatly reduced rate. This helps “flush” the
the T-10 while simultaneously insuring that it does not “over-speed”

The Need for Correct Sizing
Historical “Rule of Thumb”:
Old sizing conventions - 3” meter for 3” pipe
Actual Realization:
Flow capacity not always dictated by pipe size
More and more customers use low flow devices - e.g. ULF Toilets
= less consumption
Often consultants recommend larger meter due to future growth
which never occurs
Buildings/facilities no longer used for original intentions - e.g.
processing plant used converted to office space
Sizing Meters
ALWAYS based on flow requirements
Not based on pipe size

Meters”

• Pressures
• Type customer
• Fixture values

WHERE PEOPLE LIVE!!
Low To High Continuous Flow Rates
Any TRU/FLO meter applications that utilize the same
service line to provide fire protection…An example would
be a looped water service that has fire hydrants on the
same line.
WHERE PEOPLE WORK AND LIVE!!
HP Protectus III meter
Why Replace Old Meters
Increasing Problems with Unaccounted for water
Increased focus on Revenue Recovery through
more accurate meters
Rising Water Demands
Decaying Infrastructure
Meter Replacement can be less expensive than
repair
Increased Operating Costs
Why we recommend a Meter Strainer
Use of strainer strongly recommended!
- Corrects velocity profile
- Protects turbine measuring element from debris
No strainer installed
- Risk turbine damage
- Need 6-10 (Estimated Pipe
Diameters) E.P.D. upstream
of meter.
- Test Tee at least 2 E.P.D.
downstream of meter on turbines.

Large Meter Testing
Factors to Consider:
AWWA recommends on-site testing of large meters
on a regular basis
Cost to remove and transport
Flow conditions are different
Liability if meter is contested
Benefit to cost ratio is easily determined
Correct vs Irregular Flows
But what causes irregular flows?
Generally, any
abrupt change in
the plumbing is a
potential source of
flow irregularities.

Dealing with Customer Concerns
Some Questions you can ask the homeowner if they call in
regarding a high bill:
1/ Ask them if they have experienced any recent plumbing issues
that could lead to higher than normal consumption
2/ Ask them to make sure outdoor taps are not turned on or
leaking
3/ Ask them to check their toilets to ensure the water isn’t running
through the valve
4/ Ask them to check the low flow indicator on the meter, first by
verifying all water is turned off followed by visually inspecting the
low flow indicator. If they have a leak the LFI will be turning in a
counterclockwise direction.
