The KOBOLD RCD differential pressure flow meter is suitable for monitoring water and water-like liquids. The RCD measures flow using the orifice principle. The metering orifice, located within the flow body, generates a differential pressure that varies with flow rate. This differential pressure is applied to a measuring bellows and is linked to either a 270° mechanical indicator or a Hall-Effect transducer signal feeding our integral compact electronic or full-featured electronic display and controller. The metal design has no moving parts to wear out and features an ultra-rugged design for high reliability and long service life.
The unique design of the Kobold RCD Series differential pressure flow meter features 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. Kobold RCD Series differential pressure flow meter 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.
Custom calibrations for density and viscosity are available for your Kobold RCD Series differential pressure flow meter.
