Series WPT Multi-Jet Plastic Water Meter

Specications - Installation and Operating Instructions

Bulletin F-WPT

The SERIES WPT Plastic Multi-Jet Water Meters are a series of mechanical, water

totalizing meters that display the total water usage in Gallons with m

options. They are

available in a range of body sizes and include NPT or BSPT optional couplings. The

plastic body water meters can be used in potable water applications, some corrosive

environments, or where an economical water totalizer is desired.

FEATURES/BENEFITS

• Plastic body ideal for lead free requirements

• Multi-jetdesignallowsforsimplicityandaccuracywithsideowranges,eveninlow

 owapplications

• Magnetically driven, hermetically sealed register does not leak or fog and is

completely separated from the water

• Designed for long service life and maintenance-free operation

• Integral strainer that protects meter from particulate damage

• Easy installation with included coupling adapters

• Pulsedoutputproportionaltoowallowsforremoteowtotalization

APPLICATIONS

• Low cost residential water measurement

• Agriculture (fertilizers, pesticides, and herbicides)

• Irrigation

• Remote water monitoring

Installation Instructions

1. Thoroughlyushtheservicelineupstreamofthemetertoremovedirtanddebris.

2. Remove meter spud thread protectors.

Note: To protect meter spud threads, store the meter with thread protectors in place.

3. Set the meter in the line. Install in a horizontal plane, with the register upright, in a

location accessible for reading, service and inspect. There are arrows located on

  thesideofthemeterandabovetheoutletspudwhichindicatethedirectionofow.

4. For accurate measurement, the tap height should be higher than the meter.

5. Do not over-tighten connections; tighten only as required to seal. Do not use pipe

sealant tape on meter threads.

With upstream shutoff valve only:

6. Open shutoff valve slowly, to remove air from meter and service line. Open a faucet

slowly to allow entrapped air to escape. Close the faucet.

With both upstream and downstream shutoff valves installed:

7. Test the installation for leaks: Close the outlet (downstream) shutoff valve.

Open the inlet (upstream) shutoff slowly until meter is full of water. Open the outlet

(downstream) valve slowly until air is out of the meter and service line. Open a

faucet slowly to allow entrapped air to escape. Close the faucet.
