HP PROTECTUS®III Installation and Maintenance Guide 1
Chapter 1: Product Description
This guide provides installation and maintenance instruction to help achieve maximum
performance of the High Performance (HP) PROTECTUS®III Fire Service Meter.
The HP PROTECTUS III meter measures both domestic and fire service water usage through a
single water line. The HP PROTECTUS III meter measures extremely wide flow ranges
accurately. All Neptune®fire service meters meet or exceed American Water Works
Association (AWWA) C703 Standard, are certified to NSF/ANSI 61, and are Underwriters
Laboratory (UL) listed and Factory Manual (FM) approved for fire service use.
The HP PROTECTUS III key features include:
lWide operating range.
lComponent repair and maintenance.
lRolled seated registers.
Figure 1 – HP PROTECTUS®III

Components
The HP PROTECTUS III has five primary measurement components:
lTurbine measuring element.
lT-10®bypass meter.
lThrottle valve located inside the T-10 bypass meter.
lKnuckle valve.
lUL / FM strainer.
Turbine Measuring Element
"Unitized Measuring Element (UME)" on page16 shows the turbine measuring assembly
removed from the meter. Key components of the turbine measuring element are:
lO-ring assembly that seals the measuring element.
lTurbine / rotor.
The turbine measuring element sits in front of the knuckle valve and handles medium to high
flow.
T-10®Bypass
Figure 1 on page 1 shows the T-10 bypass on the left side of the assembly. The T-10 bypass
meter captures the low flow that passes through the HP PROTECTUS III. When the flow rate is
low, the water hits the knuckle valve located behind the turbine but it is not strong enough to
overcome the spring force of the knuckle valve. Therefore, it is diverted through the T-10 on
the bypass.
Throttle Valve
The T-10 bypass meter contains a throttle valve in the meter outlet. See "Throttle Valve Push
Button" on page20. The throttle valve regulates the amount of flow that passes through the
T-10 bypass. The valve protects the T-10 from excessive usage and facilitates the meter’s
transition through crossover.
Do not replace the T-10 on an HP PROTECTUS III bypass with a T-10 meter that does not
have the throttle valve installed in the T-10 outlet. Make sure the throttle valve is present in
the outlet of the meter used.
2 HP PROTECTUS®III Installation and Maintenance Guide
Chapter 1: Product Description

Knuckle Valve
The knuckle valve sits behind the turbine measuring element. It is a rubber-faced disc that is
held closed with linkages. When the flow rate is low, the water does not have enough force to
overcome the knuckle valve. The water hits the face of the knuckle valve and is diverted to the
T-10 bypass. As the flow rate increases the water pushes the knuckle valve open. When the
water increases in flow rate and the knuckle valve transitions from closed to open, the meter
is transitions through a state know as crossover. After transitioning through cross over, the
meter is in a medium to high flow range.
The T-10 bypass continues to constantly measure flow. The T-10 bypass should always be
registering some flow as long as the flow rate is above the T-10’s minimum operating rate.
The turbine measuring element can register flow when the rate is medium to high.
UL / FM Basket Strainer
The strainer in the HP PROTECTUS III meter is a UL / FM-approved strainer specially designed
to handle fire service applications. The round style of the strainer allows debris to fall to the
bottom of the strainer housing. This is significant, because the meter must deliver the flow
rate required for a fire situation, even if debris has entered the meter. By having the debris fall
to the bottom of the strainer housing, it keeps the debris out of the line and does not
obstruct a large flow.
You can remove and clean the basket when necessary. There is an o-ring seal between the
strainer cover and the body to protect against leaking."Strainer Case O-Ring" on page28.
HP PROTECTUS®III General Information
The following sections provide general information about the HP PROTECTUS III meter.
Operation
At low flow rates, all flow goes through the bypass meter. As flow increases, pressure loss
through the bypass meter increases, and the knuckle valve opens. This condition occurs
when a fire sprinkler system goes into operation and permits flow through the main turbine
meter. As flow decreases, reduced pressure loss closes the knuckle valve, and flow is again
directed through the bypass meter.

Chapter 1: Product Description

Construction
The HP PROTECTUS III meter includes:
lStainless steel mainline body.
lKnuckle valve (rubber-faced, stainless steel spring-loaded type).
lStainless strainer body with stainless steel basket.
lHP Turbine measuring element.
lBronze bypass assembly.
lLockable ball valves used on bypass.
lThrottle valve.
l1-inch T-10 meter (on 4-inch size).
l1.5-inch T-10 or 1.5-inch HP Turbine meter (on 6-inch sizes).
l2-inch T-10 or 2-inch HP Turbine meter (on 8-inch and 10-inch sizes).
See Appendix B, HP PROTECTUS III Parts List for additional information.
Warranty
Neptune provides a limited warranty for its HP PROTECTUS III meters for performance,
materials, and workmanship. The stainless steel body is warranted for 20 years, 10 of which
are prorated. Neptune fire service cold water meters perform for a period of one year from
date of shipment, to American Water Works Association (AWWA) accuracy standards for new
water meters.
You can replace major inline components to maintain the meter, or use a factory-calibrated
Unitized Measuring Element (UME).
