Mass Flow Controllers Type 8626 are succinct devices that control the mass flow rate of gases. They regulation the set flow velocity irrespective of interference including pressure drops or provisional 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 that event, the electrical thermal resist and the measuring resistance are adjusted to a constant temperature difference. Both resistances are directly in the gas stream; and three resistances are out of it. All resistances are combined in an electric bridge. The first resistance is measures the temperature of the fluid. The second, low resistance, is constantly heated to maintain an expressly specified excess temperature relative to the temperature of theliquid. Due to the reality that the resistances are situated directly in the channel, the instrument have splendid dynamics: the time for reaction when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not polluted.
