Compressed Air Analysis with D300

With the multifunction measuring instrument D300 the user gets a survey on the whole compressed air system

All relevant measured data for an economic operation of the compressed air station at a glance:

  • Actual air consumption in m³/h or m³/min
  • Total air consumption in m³
  • Pressure dew point in °Ctd
  • Line pressure in bar
  • Current consumption in A
  • Temperature in °C

Sensor Options for D300

Pre-installed pipe sections with ball valve

Special features • Measuring section made of stainless steel 1.4301 incl. ball valve

  • up to DN 65 (G 2 1/2″) with external thread ISO 228/1
  • from DN 80 with weld neck flange according to DIN 2633

In order to maintain the accuracy stipulated in the data sheets, the sensor must be inserted in the centre of a straight pipe section with unhindered flow characteristics. Unhindered flow characteristics are achieved if the sections in front of the sensor (inlet) and behind the sensor (outlet) are sufficiently long, absolutely straight and lack obstructions such as edges, seams, curves etc. Careful attention must be paid to the design of the outlet section as obstructions can cause counter-flow turbulence as well as turbulence in the direction of the flow.
