Differential Pressure Flowmeter

The RCD Series Differential Pressure Flowmeter measures flows of liquids and compressed gases using the orifice principle. The orifice, located in the 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.

The unique KOBOLD design features a single measuring bellows making it’s accuracy un-affected by system pressure fluctuations. All versions are manufactured with a measuring bellows made of 316-Ti stainless steel, making the bellows extremely strong and resistant to wear. The meter movement is a single fulcrumed lever design which is simple, yet very reliable with a minimum of wear parts. The RCD Differential Pressure Flowmeter 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 such as digital or bargraph displays, adjustable switches and flow transmitters.
