RCD flowmeter

The new 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 its accuracy unaffected 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 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.
