The in-line Seametrics WJ Series turbine flow meters are dry-register mechanical totalizers that offer accurate, economical reading of high flows with low pressure loss. The WJ Series turbine flow meter features a horizontal-axis turbine that drives a vertical shaft, which is magnetically coupled to the sealed register. In addition to mechanical totalizing, the WJ Series registers can be equipped with magnetic pulse reed sensors well suited for remote totalizing, pacing of electronic metering pumps, and water treatment applications.

The body of the WJ Series meter is manufactured of tough ductile iron and epoxy-coated for protection. Tungsten steel shafts and jewel bearings further enhance the durability of this flow meter. Simple removal of the top flange brings out all parts for inspection, repair, or replacement. The WJ Series has a tamper-evident seal to call attention to unauthorized access. The pulse output / reed switch option is necessary in order to select a pulse rate.

Accuracy is ±2% above transition flow and ±5% below transition. Flanges are 150 lb. ANSI drilling. Maximum pressure is 200 psi (14 bar) with maximum temperature of 105°F (40°C). The rugged construction and epoxy-coated ductile iron body ensure long-term reliability in demanding applications.
