Multifunction Readout Unit w/Integrator & Alarm

When connected to your mass flow controller or meter, Model CR-500 Readout Unit provides multiple functions, including flow measurements and control, cumulative flow calculations, alarm outputs, and so on. This readout unit incorporates RS485 data communication kit. A number of the CR-500 units can be controlled from a host computer.

  • Compact size(96 mm wide x 48 mm high)ideal for panel layout
  • Multiple functions, such as 6-digit display of total flow,individual alarm outputs for the upper/lower limits, etc.
  • Mass flow meters can be controlled from a computer via RS 485 interface.
  • Remote control of both analog and digital signals is possible from an external device.
  • Mass flow controller supply voltage:±15VDC(300 mA max. each)
  • Can be used anywhere in the world as it can be driven at a voltage within the range of 85 to 264VAC.
  • Tank pressure control
  • Control of constant flows of mixed gases
