RCD - Venturi Differential Pressure Orifice Flow Meter for Liquids

Brand: KOBOLD Instruments, Inc

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.
