CHAPTER OVERVIEW

1

The High Performance PROTECTUS®III is designed to measure both domestic and fire service water

usage. This unit is intended for installation where one water line serves both domestic and fire

services. In order to achieve maximum performance in actual service, it is essential that these

installation and maintenance instructions be followed.

If you encounter any problems with the installation or operation of your HP PROTECTUS III,

please call Neptune at (334) 283-6555 and ask to speak with an Applications Engineer.

HP PROTECTUS INSTALLATION AND MAINTENANCE GUIDE 2-1

CHAPTER INSTALLING HP PROTECTUS III

2

This chapter is designed to take you through the installation process for the HP PROTECTUS III.

The HP PROTECTUS III will operate more accurately and reliably if installed and maintained properly. HP

PROTECTUS III meter performance is directly related to the flow conditions of the water entering the turbine

portion of the meter. The entering flow is properly conditioned by a strainer installed immediately upstream

of the turbine portion of the meter.

The HP PROTECTUS III Meter Assembly includes the required UL Listed and FM Approved basket-type

strainer in front of the fire service turbine and bypass. The strainer, in addition to protecting the meter from

debris in the line, also corrects the velocity profile of the flow to the turbine meter and virtually eliminates

the effects of upstream piping variations. Proper service and cleaning of the strainer is important for long

term reliability and performance of the turbine measuring element.

When installing Neptune meters with a strainer,aminimum of four (4) pipe diameters of straight run pipe

(can include components that are fully open in their normal operating position) is required upstream and

downstream of the meter/strainer assembly.

If a Neptune meter is installed without a strainer,aminimum of eight (8) to ten (10) pipe diameters of

straight run pipe (can include components that are fully open in their normal operating position) is required

upstream of the meter inlet and four (4) diameters downstream.

INSTALLATION INSTRUCTIONS

The HP PROTECTUS III Meter Assembly should be lowered into the meter vault and positioned in the

setting via chains or straps through the lifting hooks on the top of both the strainer and DC valve. No

attempt should be made to lift the assembly by a single center strap around the meter body, or by either

end alone. The recommended installation of the HP PROTECTUS III is in a horizontal position with its

arrow pointing in the direction of the water flow. The bypass meter may be installed on either side of

mainline meter. Prior to installation, inspect the valve clapper on the detector and check for freedom of

movement. A full size bypass around the assembly is recommended as it provides uninterrupted service

capability during meter servicing periods.

RECOMMENDED INSTALLATION

2-2 HP PROTECTUS INSTALLATION AND MAINTENANCE GUIDE

As indicated previously, the required UL Listed and FM Approved strainer provides protection against

meter damage from rocks and debris in the lines and virtually eliminates the effects of variations in

upstream piping.

Atest port is provided on the top of the detector check valve section to allow a means to field test the meter

without removing it from the line. An optional method of testing the meter is available with the use of a

bypass plug located on the side of the detector check valve. Access to this plug may be limited depending on

which side of the detector check valve you trim the bypass and the bypass plug’s proximity to the vault wall.

When installing an HP PROTECTUS III Meter Assembly, normal good piping practice should always be

followed. In particular, all gaskets should be centrally located on their flanges with no overlap or interference

with the pipe diameter.

The HP PROTECTUS III Meter Assembly must operate in a completely filled line at all times. The downstream

piping must always provide sufficient back pressure to maintain a full line at the meter.

Before putting the HP PROTECTUS III Meter Assembly into service, follow these steps:

1. Close all valves (mainline and bypass).

2. Turn air bleed screw on detector check valve and strainer cover counter-clockwise

one to two turns.

3. Slowly open mainline inlet side gate valve to pressurize meter.

4. Close air bleed screws (clockwise) when air is completely vented and no “spitting” occurs.

5. Slowly open outlet side gate valve until downstream line is pressurized.

6. Slowly open upstream ball valve on bypass to pressurize bypass meter.

7. Slowly open downstream ball valve on bypass.

After installation, it is important that the upstream (inlet) valve be put in the “full open” position during

service. All throttling should be done only on the downstream (outlet) side of the meter.

BEFORE OPERATION

HP PROTECTUS INSTALLATION AND MAINTENANCE GUIDE 3-1

CHAPTER MAINTENANCE

3

If you find that your HP PROTECTUS III is not operating as expected when installed, use the following

guidelines to try to determine the source of the problem.

HP TURBINE METERS

When maintenance is necessary,the complete unitized measuring element (UME) may be quickly and easily

interchanged with a factory-calibrated unit by following these steps:

1Close all valves (mainline and bypass).

2Remove cover bolts.

3Remove cover and turbine measuring element from maincase.

4Remove old maincase gasket and replace with a new gasket.

5Install factory-calibrated UME into maincase.

6Replace cover bolts.

7Tighten cover bolts.

8Follow steps 2 through 7 from “Before Operation” section above.

All UMEs have been factory calibrated and should not require field calibration.

The complete UME should be tagged and returned for service to the nearest Neptune Factory. If the customer

does not have a spare unit, a factory-calibrated UME may be purchased directly from Neptune or one of its

authorized distributors. Neptune encourages all customers to purchase either a spare UME or a blank cover

to enable them to avoid service interruptions.

3-2 HP PROTECTUS INSTALLATION AND MAINTENANCE GUIDE

Neptune equips all new turbine meters and UMEs with a calibration vane. Should field calibration of the

turbine element be required, the following steps should be followed:

1Remove seal pin from register and twist off register.

2Loosen lock nut on adjusting stem by turning counter clockwise.

3Insert slotted screwdriver into slot in top of adjusting stem, and (a) turn clockwise to

decrease registration, or (b) turn counter-clockwise to increase registration.

Turning the adjustment stem 15º in either direction results in approximately one percent change in

registration. The full range of the calibration vane is 180°.

CHAPTER MAINTENANCE

T-10 DISC METERS

Clean line before installation. Do not distort meter during installation on pipe. If thread compound is used,

donot allow inside meter itself. When desired, owner maintenance is easily accomplished by replacing

major components.

DETECTOR CHECK VALVES

Detector Check Valves are water lubricated and virtually maintenance free. Should the valve give

indications of improper operation, including (a) leakage back to the service side of the system, or (b) valve

not open fully on large volume demand, then:

1Remove valve top cover.

2Inspect parts for freedom of movement.

3Inspect valve for obstructions.

4Move clapper manually to ensure freedom of movement.

5Replace valve top cover.

6If further servicing is necessary, contact Neptune Customer Support.

STRAINER

For maximum efficiency,determine length of time it takes for baskets to become approximately one-third

clogged. Remove top cover and clean basket. Replace basket in strainer in original position and tighten

cover. Replace gasket if necessary. Spare gaskets will facilitate shorter “shut-down time.” Pressure gauge

installed before and after strainer in line will indicate pressure loss due to clogging and may be used as a

guide to determine when cleaning is required. Strainer is equipped with a flushing port and open-bottom

basket for removal of sediment. In addition, strainer may be equipped with a “blow-down valve” to

facilitate easier cleaning.
