Bronkhorst High-Tech BV the leaders in Mass Flow Meter / Mass Flow Controller technology for gases and liquids, Pressure Controllers and Evaporation Systems.
The Constant Temperature Anemometry - CTA - gas flow sensor consists of two stainless steel probes, the first being a heater and the second being a temperature sensor. A constant temperature difference (ΔT) is created between the probes.
Regardless of the actual flow rate CTA is aiming to keep this delta-T or temperature difference (ΔT) between both sensor pins at a constant level.
The flow rate and the heater energy required to maintain this constant ΔT 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.
Compared to traditional thermal Mass Flow Meters and Mass Flow Controllers with bypass, the construction of the direct measuring CTA principle is less sensitive to humidity and contamination.
Thermal mass flow meters are used to measure mass flow of low gas flow. A mass flow controller is a flow meter combined with a control valve.
