RCD - Differential Pressure Flowmeters

Features● 0.2-0.88 to 100-600 GPM Liquids ● 0.3-3 to 250-1650 SCFM Gases ● 1/2” to 3” Line Sizes ● Bronze or 316-Ti Stainless Steel ● Mechanical Indicator, Digital Indicator, Transmitters and Switches Available ● Custom Calibrations for Density and Viscosity

The RCD series differential pressure flowmeter measures flows of liquids and compressed gases using the orifice principle. The orifice, located inthe flow body, generates a differential pressure which varies with flowrate. The differential pressure is applied to a measuring bellows. The measuring bellows is linked either to a mechanical indicator, or to a hall effect sensor, which is input to a compact or full featured electronic display and controller.

RCD series Differential Pressure Flowmeter

Specifications
The unique KOBOLD designfeatures a single measuring bellows making its accuracy unaffected by system pressure fluctuations. The meter movement is a single fulcrum lever design which is simple, yet very reliable, with a minimum of wear parts. The RCD is available with bronze or stainless steel bodies ranging in size from 1/2” NPT to 3” NPT. The various electronic display and control units offer a variety of options suchas digital or bargraph displays, adjustable switches and flow transmitters.
