Mass Flow Controllers Type 8626 are compact arrangement that monitoring the mass flow of gases. They command the set flow rate regardless of obstruction for instance pressure drops or temporary flow resistance. Flow regulator consist of a flow meter, an electronic module, as well as a proportional valve. Inline sensors function in the constant temperature anemometers mode. In this case, the electrical thermal resist and the measuring resistance are adjusted to a constant temperature differentiation. Both resistances are directly in the gas stream; three more resistances are outside him. All resistances are united in an electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to sustain a clearly defined excess temperature relative to the fluid temperature. Due to the reality that the resistances are disposed at once in the channel, the devices have excellent dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
