RCD

Differential Pressure Flow Meter/ Monitor

The KOBOLD flow meter model RCD is used for measuring and monitoring liquid and gas flows. The device works on the well-known principle of the Venturi nozzle. A small pressure difference proportional to the flow is produced by the flowing medium at an orifice constriction (nozzle) in the device housing. The shape of the nozzle is based on the flow, whereby the flow characteristic remains constant over the entire measuring range. Drill holes are locked in the housing fitting to absorb the resulting differential pressure and transfer it to a differential-pressure measuring cell fitted in the display case. If the flow is exceeded the differential pressure measuring cell is protected by locking pins. On mechanical displays the flow rate measured by the pressure measuring cell is transferred via a pointer movement to the pointer indictor calibrated in l/min water or Nm³/h air. On electronic displays the mechanical motion is converted to an electrical signal by a Hall-sensor. Various electronic modules are then used to display and monitor the volumetric flow. Special scales are available for all media at any pressure and any temperature.
