Model 900B Impeller-Type Flow Meter

The Model 900B Flow Meter features interchangeable inlet inserts, containing three different sized offices. These orifices are precalibrated to accurately monitor flow in three progressive flow ranges: Low (68-172 BPD), Mid (172-1543 BPD) and Hi (1543-3086 BPD).

Designed for water flood applications the Model 900B is constructed of abrasive and chemical resistant stainless steel capable of handling pressure up to 2,000 psi. The Model 900B design offers quick access to the internal components without the need to remove the meter from the flow line.

Operating Principle
The Model 900B Impeller-type Meter design features interchangeable inlet inserts, containing three different sized orifices. These orifices are precalibrated to accurately monitor flow in three progressive flow ranges; a low flow range of 68-172 BPD a mid flow range of 172-1543 BPD and a high flow range of 1543-3086 BPD. These inlet inserts extend the meter's overall flow range from 68 to 3086 BPD. Liquid enters the meter inlet, passing through the preselected inlet nozzle, flowing into the cylindrical measuring chamber. In the measuring chamber, the flowing liquid is forced to separate into two equal streams, traveling in a 360º loop. The streams are further channeled, by the special configuration of the measuring chamber, into a series of vortices which cause the rotary vaned impeller to rotate in direct proportion to the flow rate. These dual flow streams are recombined into a single stream at the meter outlet.
