Special mechanical features:

  • Robust impact-proof aluminum die cast housing for the outdoor area IP 67
  • All medium-touching parts made from stainless steel 1,4571
  • As immersion sensor suitable for 3/4“ up to DN 500
  • On request with ATEX approval ATEX II 2G Ex d IIC T4
  • On request with DVGW approval for natural gas (up to 16 bar)
  • Pressure range up to 50 bar, special version up to 100 bar
  • Temperature range up to 180 °C
  • No moving parts, no wearout
  • Sensor tip very robust, easy to clean
  • Easy mounting and dismounting under pressure via 1/2“ ball valve
  • Housing twistable, display twistable by 180°
  • Safety ring for mounting and dismounting under pressure
  • Depth scale for precise installation

Special measurement technology features:

  • 4 values in the display: Nm³/h, Nm³, Nm/s, °C units freely adjustable
  • Min/max values and daily/hours/minutes average values freely adjustable
  • All measured values, settings like gas type, inner diameter, serial number and so on retrievable via Modbus RTU
  • Comprehensive diagnosis functions readable at the display or remote access via Modbus like e. g. exceeding of max/min values °C, calibration cycle, error codes, serial number, all parameters readable and adjustable
  • Notification in case of exceeding of the calibration cycle
  • Standard version accuracy 1.5 % of m.v. ± 0.3 % of f.s.
  • Precision version accuracy 1.0 % of m.v. ± 0.3 % of f.s. up to
  • 40 calibration points with certificate
  • Measuring span of 1 : 1000 (0.1 up to 224 m/s)
  • Configuration and diagnosis via display, hand-held instrument
  • PI 500, PC service software on-site
  • Gas type (air, nitrogen, oxygen, argon and so on) freely adjustable
  • Reference conditions °C and mbar/hPa freely adjustable
  • Zero-point adjustment, leak flow volume suppression
  • Pressure loss negligible
  • Flow measurement in both directions via flow direction switch
