Product Description

Krohne Variable Area Flowmeters H210/RR H250 M40/M9 Flow Transmitter





The H210 is the standard variable area (VA) flowmeter for the process and OEM industry. The VA meter combines mechanical flow measurement of liquids or gases with state-of-the-art communication capabilities. The device is modularly extendable. Additional electronic modules can be added or replaced at any time without process interruption. In this way, its functionality adapts to new requirements – from analogue flow measurement without auxiliary power to digital integration into a fieldbus system.



  • Simple, low-cost installation: able to measure and display without auxiliary power supply
  • Unique modularity and serviceability: Limit switches, 2-wire 4…20mA, totalizer with LCD and pulse output, fieldbus interfaces
  • NE 107 device and application diagnostics with CFM (Continuous Float Monitoring), e.g. for float blockade detection
  • Universal ex-concept: Explosion proof and intrinsically safe
  • Various stainless steel and alloy sensor materials
  • Optional stainless steel housing for corrosive atmospheres
  • Ingress protection IP66 and IP68 / NEMA4X and NEMA6, IP69K optional
  • Full scale value for liquids: 10…120,000 l/h / 5…32,000 GPH
  • Full scale value for gases: 0.7…2800 m3/h / 25…100,000 SCFH
  • Turndown ratio 10:1 (optional 100:1)
  • Maximum measuring error: ±1.6% (acc. to VDI/VDE 3513-2) or ±1.5% of full scale
  • Suitable for use in Safety Instrumented Systems with SIL 2, in redundant design (1oo2) also in SIL 3 applications (type A device)
  • Optional hygienic design for use in the food and pharmaceutical industry
