The C400 series

C400 flow / consumption sensor (insertion type)

 

 

The C400 flow sensor  is based on the thermal mass flow principle. It measures volumetric standard flow over a wide measuring range. The result is pressure and temperature independent.


The sensor installation into the pipe is done through a ½” ball valve. This makes it possible to do the installation under pressure without shutting down the compressed air line.The sensor is available in two measuring ranges and with or without display. The version with display shows the actual volumetric flow and the total consumption. Via the keyboard tube diameters and the consumption counter can be set.


Every sensor includes an analogue output (4…20mA) for flow and an isolated pulse output for the consumption counter.

Special Features

  • Integrated display for m3/h and m3
  • Depth scale for accurate installation
  • Usable from 1/2” to 12” (DN 300)
  • Easy installation under pressure
  • 4...20 mA analogue output for m3/h resp. m3/min
  • Pulse output for m3
  • Inner diameter adjustable via keypad
  • Consumption counter resettable
  • Insertion type sensor for installations under pressure
  • Thermal mass flow, independent of pressure and temperature changes
