Series WPT Multi-Jet Plastic Water MeterSpecifications - Installation and Operating InstructionsBulletin F-WPTThe SERIES WPT Plastic Multi-Jet Water Meters are a series of mechanical, water totalizing meters that display the total water usage in Gallons with m3 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 flow ranges, even in low flow 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 flow allows for remote flow totalizationAPPLICATIONS• Low cost residential water measurement• Agriculture (fertilizers, pesticides, and herbicides)• Irrigation• Remote water monitoring Installation Instructions1. Thoroughly flush 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 flow.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.SPECIFICATIONSService: Water.Wetted Materials: Body: Nylon 66; Couplings: Nylon 66, 1-1/2˝ (40 mm) sizes lead free ECO BRASS® alloy; Measuring Chamber: ABS Plastic.Flow Range: See model chart.

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.MODEL CHARTModelSizeCoupling SizeGPM (Gallons Per Minute)Display Max(Gallons)Pulse Rate(Gal/Pulse)Weightlb (kg)Max FlowNominal Flow RangeTransitional FlowWPT-A-C-01-100WPT-A-C-02-100WPT-A-C-03-100WPT-A-C-04-100WPT-A-C-05-1005/8˝ x 1/2˝ 5/8˝ x 1/2˝ 5/8˝ x 1/2˝ 5/8˝ x 1/2˝ 5/8˝ x 3/4˝5/8˝ x 3/4˝5/8˝ x 3/4˝5/8˝ x 3/4˝3/4˝ x1˝3/4˝ x1˝3/4˝ x1˝3/4˝ x1˝1˝1˝1˝1˝1-1/2˝1-1/2˝1-1/2˝1/2˝ NPT1/2˝ NPT1/2˝ NPT1/2˝ NPT3/4˝ NPT3/4˝ NPT3/4˝ NPT3/4˝ NPT1˝ NPT1˝ NPT1˝ NPT1˝ NPT1˝ NPT1˝ NPT1˝ NPT1˝ NPT1-1/2˝ NPT1-1/2˝ NPT1-1/2˝ NPT202020202020202030303030505050501001001001 to 201 to 201 to 201 to 201 to 201 to 201 to 201 to 202 to 302 to 302 to 302 to 303 to 503 to 503 to 503 to 505 to 1005 to 1005 to 1000.250.250.250.250.250.250.250.250.50.50.50.50.750.750.750.751.51.51.59,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.99 9,999,999.9 9,999,999.9 9,999,999.90.11000.11000.11000.11001001.55 (0.7)1.55 (0.7)1.55 (0.7)1.55 (0.7)1.77 (0.8)1.77 (0.8)1.77 (0.8)1.77 (0.8)2.43 (1.1)2.43 (1.1)2.43 (1.1)2.43 (1.1)2.43 (1.1)2.43 (1.1)2.43 (1.1)2.43 (1.1)4.41 (2)4.41 (2)4.41 (2)ECO BRASS® is a registered trademark patent by Mitsubishi ShindohWHL®DWYER INSTRUMENTS, INC.P.O.

In the example below, the Five-Digit Totalizer reads 13800 (138 x 100), and the dials read 0 (0 x 10), 0 (0 x1), and 0 (0 x 0.1) respectively. The total flow is 13800.0MAINTENANCE/REPAIRUpon final installation of the Series WPT, no routine maintenance is required. The Series WPT is not field serviceable and is not possible to repair the unit. Field repair should not be attempted and may void warranty.WARRANTY/RETURNRefer to “Terms and Conditions of Sale” in our catalog and on our website.
