Mainline Propeller Water Meter

Mainline Propeller meters (Model 101/102) are primarily intended for accountability measurement of potable and non-potable cold water with flow in one direction only. Registration accuracy is 100% ± 2% of actual throughput within specified normal flow ranges. Because all appropriate parts are sealed for protection, the meters can be used in water containing particulate solids (such as sand), without causing undue wear.

Mainline Propeller meters are available in weld-on, clamp-on, plain tube and flanged end styles for applications where accountability rather than revenue is a factor. Typical applications include pump discharge, fresh water treatment plant measurement, sewage treatment plant effluent and chemical feed control. Available with Electronic Rate of Flow (E-ROFI) registers.
