Mass Flow Controllers Type 8626 are succinct devices that inspection the mass flow rate of gases. They control the set flow velocity irrespective of hurdle including drop in pressure or provisional resistance to flow. Flow regulator consist of a flow meter, an electronic module, and a proportional valve. Inline sensors operate in the constant temperature anemometers mode. In that event, the electrical thermal resist and the measuring resistance are set to a constant temperature difference. Both resistances are immediately in the gas stream; three more resistances are outside him. All resistances are united in an electric bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to maintain an expressly defined excess temperature relative to the temperature of thefluid. Due to the fact that the resistances are situated at once in the channel, the devices have splendid dynamics: the time for reaction when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
