Benefits of instruments in Bronkhost liquid flow portfolio

  • Independent of the fluid properties and therefore able to handle unknown fluids.

  • High dosing accuracy; to support you reduce waste of ingredients.

  • Flow computer on-board for compact control loop with fast response time.

  • Low cost; no maintenance necessary as the liquid flow instrument has no moving parts.

  • Measurement of multi parameters: flow, temperature, density and sound of speed.

  • Thermal mass flow instruments from 5 mg/h - 1 kg/h

  • Coriolis mass flow instruments 50 mg/h - 600 kg/h

  • Volumetric flow instruments based on ultrasonic wave technology from 2 ml/min - 1500 ml/min

  • Instruments based on vortex and electromagnetic working principles up to 250 l/min

Liquid flow measurement and control

Liquid flow measurement and control plays an elementary role in many processes. Applications can be found in food & beverage industrypharmaceutical industrybiotechnology and chemical research labs or pilot plants and many others. In all these applications liquid flows need to be measured and controlled accurately, like in a dosing process. For these dosing processes we supply flow meter/pump combinationscontrol valves and  customised liquid dosing skids.

From a variety of Bronkhorst products

ES-FLOW™ Low-Flow Ultrasonic Flow Meters / Controllers

Liquid Independent Measurement of Low Volume Flow Rates

ES-FLOW™ are Volumetric Liquid Flow Meters for very low flow ranges. The instruments operate on a innovative measuring principle, using ultrasound in a very small, straight tube. A wide range of liquids can be measured independent of fluid density, temperature and viscosity.

  • Flow rates from 0,4 ml/min up to approx. 1500 ml/min, depending on e.g. the available pressure drop.

mini CORI-FLOW™ Coriolis Mass Flow Meters & Controllers

Mass Flow Measurement of low flow rates, independent of fluid properties

With the development of the mini CORI-FLOW™ series Bronkhorst achieved a technological breakthrough in Coriolis mass flow measurements and control, by realising a compact, cost-effective Coriolis Mass Flow Meter/Controller for accurate measurement and control of (very) low flow rates. The unique design of the miniature Coriolis sensor features unsurpassed performance, even with changing operating conditions in pressure, temperature, density, conductivity and viscosity.

Advantages & Benefits

  • Lowest range 0…5 g/h

  • Highest range 0…300 kg/h

LIQUI-FLOW™ Thermal Mass Flow Meters / Controllers for Liquids

Through-Flow Measurement of Low Liquid Flow Rates

LIQUI-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.

Advantages & Benefits

  • Lowest range 0,25 ... 5 g/h

  • Highest range 20 ... 1000 g/h for fluids with thermal properties similar to H2O)
