Mass flow sensor for gases, bypass principle In thermal instruments based on the bypass principle, only part of the gas stream flows through the sensor (as shown in figure A). The gas stream through the sensor is warmed up by two heaters (RHT1 and RHT2). Accordingly, the temperature of the tube is measured at two points (T1 and T2).
Once a corpus like our patented flow sensor profile is being brought into parallel flow with the velocity of w, the fluid will partly pond while passing the barrier. The streamline flowing in the middle of the ponding area, the ponding flow line, hits the barrier vertically. The fluid will totally calm down at this very point, called the ponding point. As ponding flows are always laminar– at ...
The FS2 thermal gas flow sensor works on the calorimetric principle and consists of four platinum thin-film resistors - one platinum thin-film resistor used as heater, two platinum thin-film resistors used to detect the flow speed and flow direction and a temperature sensor for ambient temperature measurement. The heater is surrounded by two temperature sensors. As flow passes across the ...

Every flow of gas over the membrane causes a thermal transfer of heat to the temperature sensor positioned downstream and, because of the resulting temperature difference, creates a precisely measurable signal. The microthermal flow sensor is integrated by etching the pressure-stabilized membrane, which has a passivation glass layer, into the silicon chip. The CMOSens® Technology …

The gas stream through the sensor is warmed up by two heaters (RHT1 and RHT2). Accordingly, the temperature of the tube is measured at two points (T1 and T2). With no flow measured, the temperature differential between ...
THERMAL MASS FLOW SENSOR FOR GAS. Inline / Direct-through / CTA principle CTA is the abbreviation of Constant Temperature Anemometry, which is also named ‘direct through-flow measurement’ or ‘inline measurement’. Therefore, this principle has no bypass sensor. Amongst various flow measurement techniques the thermal mass flow measurement based on the CTA principle is used for both gases ...
