Bronkhorst UK Ltd

Bronkhorst has successfully supplied gas, liquid and vapour flow/pressure measurement and control instrumentation to numerous industries for over 34 years. This success, entirely based upon close collaboration with their customers, has resulted in countless industry-changing advances in both measurement technology and its implementation within continuous process improvement. The latest generation El-Flow Prestige thermal mass flow meters and controllers represents a truly ground-breaking shift in versatility and user-friendliness.

  Designed for low flow ranges, the mini CORI-FLOW ML120 series of Coriolis Mass Flow Meters and Controllers has been released by Bronkhorst.

Many industries require a liquid source to be converted into a homogenous vapour. Traditional methods have involved either bubbling a carrier gas through the liquid source whilst precisely controlling the temperature and pressure, or directly introducing the liquid source onto a hot surface or plate. The former is extremely reliable, well-proven and offers high repeatability/reproducibility once the controlled process parameters have reached steady state. It is, however, less suited to applications where step changes in concentration are required, where fast switching on-off is required or where multiple liquid sources need to be introduced through one, single evaporation system. Furthermore, this system requires a large volume of potentially hazardous liquid to be housed in a pressurized (glass) container close to the application – often not ideal in highly populated laboratories. The latter has benefits as a highly simplified system however the temperature required for evaporation is much higher, the energy consumption is extremely high and variable control of flow rate/concentration can only be achieved on long cycle times.
