Bronkhorst High-Tech BV the leaders in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
The German company LaVision develops and manufactures modular laser imaging systems for the visualization of reactive and non-reactive flow processes. One of the optical techniques used is Laser Induced Fluorescence (LIF). Bronkhorst provided a solution to create an accurate mixture of nitrogen and a tracer substance, consisting of an evaporator module (VDM) and a liquid feed module. Precise control of the gas flow, liquid flow and temperature in this process are important.

One of the most important aspects of the temperature analysis is a precise and repeatable mixture of the tracer liquid and gas. The challenge is to create different but consistent mixtures for varying test conditions. Precise control of gas flow, liquid flow and temperature are key to this process.
In this setup of 2-colour Laser Induced Fluorescence (LIF) thermometry, Anisole is used as ‘colourant’ to make the internal thermal flow visible for the camera. The Anisole has to be available in vapour phase where the accuracy of the liquid Anisole flow control is crucial.
To create an accurate vapour mixture of Anisole and Nitrogen, an evaporator module is used. Small amounts of liquid Anisole (up to 25 g/h) are atomised in the Nitrogen gas flow in the Controlled Evaporation and Mixing (CEM) module, and then heated to ensure total evaporation and avoid cooling down to below condensation temperatures. At the vapour outlet, optional dilution gas is added to further reduce the concentration of Anisole in the vapour flow.
All components are assembled in a Vapour Delivery Module (VDM) which also contains the power supply, communication interfaces and a display for readout and control.
To adjust the system to the customers processes, the relevant PID parameters of the flow controllers can be adjusted via a digital (RS232 or bus) interface using the Bronkhorst software FlowPlot and FlowSuite.
