Flow measurement is recognised as one of the ‘need-to-know’ process parameters, alongside temperature, pressure and level measurement. Accurate mass flow measurement of gases is critical in operations and control of many industrial and laboratory processes.
In the food and beverage sector, the chemical industry and semiconductor fabrication, flow meters accuracy is often the determining factor between optimum quality and rejected products. In areas like laboratory research, pilot plants and custody transfer, precise and repeatable measurement is equally critical.
The Laminar Flow Element as seen in Picture 1 is a critical component of the thermal mass flow meter using the bypass principle. The functionality of the Laminar Flow Element (LFE) is to create a shunt. In the case of a thermal mass flow meter based on a bypass principle the mass flow is measured in a bypass of the main flow channel. Due to the specific dimentions of the LFE the same linear pressure/ flow characteristics as the capillary sensor tube can be created.
The LFE consists of thin discs with etched channels. A combination of multiple thin discs allow the measurement of very small (less than 1 mln/min) as well as medium (20 ln/min) flow rates. These flow discs are created by Veco by using the Chemical Etching process.
Miniturisation of products – and therefore components – is a necessity for manufacturers in order to create industry-leading products. For the flow discs in LFE we applied the Chemical etching process, a subtractive manufacturing method for micro-precision parts.
EL-FLOW Prestige thermal gas flow meter is the next generation of Bronkhorst Mass Flow Meters / Controllers for gases. Nearly all core components have been redesigned and many improvements and innovations have been incorporated. With this new series Bronkhorst introduced the “Differential Temperature Balancing” technology, ensuring a superb sensor stability. You can sign in for the White Paper ‘A holistic view based on data to design components which offer optimal performance of a thermal mass flow meter/controller’, written by Bronkhorst, which describes the innovations integrated in the EL-FLOW Prestige.
