    Kobold® type DMH magnetic inductive flow meters are designed to measure and monitor the volume flow rate of liquids, pulps, pastes, and other electronically conductive media without loss of pressure and can be used in rugged environments. The measuring transducer can be connected to the sensor directly or mounted remotely. Pressure, temperature, density, and viscosity do not affect the volume measurement. Large solids and gas bubbles should be avoided. The DMH offers a variety of lining, electrode, and process connection options.

  • The KOBOLD DON is an oval gear, positive displacement flowmeter that provides precision flow measurement of most clean liquids, regardless of the media's conductivity.

    Moving Parts Viscous Liquid (Oils, Syrups, etc.) 1 - 1 1/2, 1/8 - 3/4, 2 - 3, 4+ Positive Displacement

    Kobold® type DON oval gear flowmeters are categorized as positive displacement flow technology. When liquid flows through this type of positive displacement flowmeter, two oval geared rotors measure a constant volume per rotation within a precisely machined measuring chamber. With each rotation, a constant volume of liquid is measured. The rotation of the oval gears is sensed via magnets embedded within the rotors. These magnets transmit a high resolution pulse output. The output signal can be processed externally via a remote display controller or LC or via a variety of output/display options available as accessories attached to the flowmeters.
