Bronkhorst High-Tech BV the leaders in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
Amongst various flow measurement techniques the thermal mass flow measurement based on the CTA principle is used for both gases and liquids. ‘CTA’ is the abbreviation of Constant Temperature Anemometry, which is also named ‘direct through-flow measurement’ or ‘inline measurement’. Mass flow meters based on the CTA principle cover a wide range of measurement and control applications in almost every industry sector.
Examples of applications are burner control, aeration processes, gas consumption measurement, leak rate tests and environmental air sampling at atmospheric conditions. Within the Bronkhorst® portfolio, these reasonably priced flow meters enlarge the scope of mass flow measurement solutions for higher flow rates, for low pressure requirements and for conditions within an application and/or local work environment that would be unsuitable for another measurement principle such as thermal by-pass.
The CTA sensor consists of two probes, the first being a heater and the second being a temperature sensor. A constant temperature difference is created between the probes. Regardless of actual flow rate CTA is aiming to keep this delta-T or temperature difference (dT) between both sensor pins at a constant level. The flow rate and the heater energy required to maintain this constant dT are proportional and thus indicate the mass flow of the gas. The actual mass flow rate is calculated by measuring the variable power required to maintain this constant temperature difference as the gas flows across the sensor.
