μ-FLOW

µ-FLOW Mass Flow Meters and Controllers for Liquids

Measurement / Control of Ultra Low Flow Rates

µ-FLOW digital Liquid Flow Meters/Controllers for low flow ranges operate on a thermal, through-flow measuring principle. The instruments are equipped with a digital pc-board, featuring self-diagnostics, alarm and counter functions, digital communication (RS232) and a variety of fieldbus options.

• Lowest range 5 ... 100 mg/h
  
• Highest range 0,1 ... 2 g/h (fluids with thermal properties similar to H2O)
  
  

Features

• No moving parts
  
• Thru-Flow measurement
  
• Attitude insensitive
  
• Fast and accurate measurement
  
• Negligible dead-volume (sensor: 1,5...33 µl)
  
• In combination with a control valve: continuous and stable control
  
• Analog or digital: RS232, PROFIBUS DP, DeviceNet™, Modbus or FLOW-BUS 
  
• Stainless Steel sensor
  
• On request: pressure rating up to 1000 bar (15000 psi)

Applications

• Pharmaceutical industry
  
• Food industry (flavors, additives)
  
• Biotechnical industry
  
• Analytical laboratories
  
• Evaporation processes (see CEM/VDM-system)
  
• HPLC/UPLC applications
