Seametric WTP Flow Meter Turbine PVC

• PVC-body turbine flow meter
• In-line, individually-calibrated turbine flow meter maximizes accuracy
• The turbine rotor is the only moving part, optimizing low-flow performance
• Solid-state pickup
• The electronic register can be meter-mounted or remote
• Available with blind pulse or 4-20 mA output
• Materials are chemical-resistant
• Can be ordered with stub ends (standard) or flanges (optional)

Installation and Connection

These water meters are not recommended for installation downstream of the boiler feedwater pump where installation fault may expose the meter to boiler pressure and temperature. Maximum recommended temperature is 120? (PVC) or 200? (Metal).

Piping Conditions.

Installing the meter with 10 diameters of straight pipe upstream and 5 downstream is recommended.

Flanges.

For WTS meters, standard flanges are 150 lb. ANSI drilling. PVC meters can be installed with optional flanges according to pipe manufacturer’s recommendations. For PVC a bolt torque of 20-30 ft-lb for 3” and 4” flanges, and 35-50 ft-lb for 6” flanges is recommended. Either partial or full-face gaskets can be used. Tighten the bolts evenly. Use care to prevent a misaligned gasket from entering the flow stream.

Position.

The WT-Series are all-position meters, operable in a vertical or horizontal position, with the meter insert in any radial position. A horizontal position is preferred if there is a risk of air becoming trapped due to constant low flows. Operating the meter in partially-filled pipe will result in inaccuracies.
