Product Features","The DRB and DPE series turbine wheel flowmeters are an economical yet very reliable solution for measuring liquid flows in pipes up to 3 inches in diameter. The unique \"insertion†impeller design protrudes minimally into the flow stream which minimizes head loss and allows measurement of dirty liquids, and liquids with high solid content, without risk of failure. The DRB and DPE series feature a PVDF impeller supported on a sapphire bearing system which provides an exceptionally long life and excellent chemical resistance properties. The DRB and DPE series are available with either bronze or stainless steel threaded bodies. A Hall effect sensor detects the passing of permanent magnets imbedded in the impeller blades. The output of the Hall sensor is converted to a linear pulse or 4-20 mA signal. Optionally, a variety of displays and controllers is available to provide flow rate indication, analog outputs and programmable setpoint switches. The DRB and DPE series' combination of simple, reliable design and variety of body materials and electronics options makes them a sure solution for the toughest flow metering applications.
