GENERAL DESCRIPTION


The 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 design 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. 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.

ORDERING INFORMATION

Ordering Codes For Gas Flowmeters

RCD - Ultra-Rugged Differential Pressure Flowmeter

HOW TO ORDER
To Properly Specify the RCD Series:

  1. Choose the ordering code for the desired range, materials and available fitting size (RCD-1105SN4).
  2. Choose the ordering code for the desired indicator type (e.g. mechanical, compact, etc.)
  3. Choose the codes for the flowmeter installed flow direction (required for mechanical indicator only):
    LT = Flow from left to right
    RT = Flow from right to left
    BL = Vertical up flow, dial on left
    BR = Vertical up flow, dial on right
  4. Specify the process media: 

    Liquids - Specify the type of liquid. If other than water, specify the viscosity and the specific gravity or density. Use option codes C or V as necessary. The RCD will be calibrated for these conditions.

    Gases -specify the type of gas. Specify the normal operating pressure and temperature. The RCD will be calibrated for these conditions.

    NOTE: Calibrations for compressed gases or liquids other than water may change the measuring range from those listed in the part number tables. Contact Flow Network to determine the corrected flow range which will be provided based on operating conditions.

    RCD Installation Piping Requirements In order to guarantee accurate readings, the RCD series must be installed with a minimum of 10 diameters of straight piping at the inlet and 5 diameters of straight piping at the outlet. This straight piping must be the same diameter as the flowmeter fittings and should have no bends, elbows, tees, valves or other plumbing appurtenances.
