Overview

The DK37 M8 is a variable area (VA) flowmeter with electrical signal output and bargraph indication or mechanical indicator with two optional limit switches. The versatile all-metal measuring device is suitable for flow measurement of gases and liquids. Due to its sturdy design, the VA meter can be used at temperatures up to +200°C / +392°F or pressures up to 220 barg / 3190 psig. It is fitted with a needle valve as standard to accurately set the flow value.

  • Simple, low-cost installation: Able to measure and display without auxiliary power supply
  • Purgemeter with 2 optional limit switches or 4…20mA/HART® for flow monitoring
  • Various stainless steel and alloy sensor materials
  • Optional surface passivation with SilcoNert®2000 for trace-level analysis
  • PPS housing as standard, stainless steel housing as option
  • Ingress protection IP66/67
  • Full scale value for liquids: 1.6…250 l/h / 0.4…67 GPH
  • Full scale value for gases: 16…8,000 l/h / 0.6…300 SCFH
  • Turndown ratio 10:1
  • Accuracy: ±2.5% (acc. to VDI/VDE 3513, sheet 2)
  • SIL 2 conform for use in Safety Instrumented Systems (SIS)
