If a Neptune meter is installed without a strainer, a minimum 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.
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.
CHAPTER MAINTENANCE 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. MAINTENANCE INSTRUCTIONS 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: Close all valves (mainline and bypass).
ADJUSTING THE CALIBRATION VANE 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: Remove seal pin from register and twist off register.
Inspect valve for obstructions. Move clapper manually to ensure freedom of movement. Replace valve top cover. If 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.
