Benefits N/A Benefits at a glance:
  • New: Unique sensitivity in the lower measuring range: Measures from as little as 6.56 f/s and thus covers the complete operating range of variable speed drive (VSD) compressors
  • Particularly suitable for extremely high flow rates
  • Flow, total consumption, temperature and pressure
  • Measurement at high temperatures, max. temperature 356 ºF
  • Can be used in pipes from 3/4" to 24"
  • Installation via 1/2" ball valve under pressure

Additional Information N/A The integrated, precise differential pressure sensor measures the differential pressure/ dynamic pressure at the sensor tip. The pressure depends on the respective gas velocity.

The flow is therefore easy to determine by means of the pipe diameter.

The additional measurement of temperature and absolute pressure and calculation of the relevant density means that measuring can be carried out for various gases, a wide variety of temperatures and pressures. 		N/A N/A
