The Blancett Series 200 and Series 900 are rugged, low-priced flow meters specifically designed to measure floodwater line flow in secondary oil recovery operations throughout the world. Using time-proven rotary vane and multi-jet impeller mechanisms, the Series 200 and 900 flow meters will provide reliable long-term measurement and totalization with minimum attention and maintenance.

The Series 200 features a radial vaned impeller, mounted on a vertical spindle within a cylindrical measuring chamber. Fluid entering the meter passes through the lower compartment of the central housing, and then enters the measuring chamber through several tangential orifices located around the cylinder. The flowing water causes the impeller blades to rotate at a speed directly proportional to flow rate. The rotating impeller is magnetically coupled to a mechanical register, and each impeller rotation is mechanically tabulated and displayed.
