Mass Flow Controllers Type 8626 are compact devices that inspection the mass flow rate of gases. They regulation the set flow rate regardless of obstruction such as drop in pressure or provisional flow resistance. 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 adjusted to a constant temperature difference. Both resistances are directly in the gas stream; three more resistances are outside him. All resistances are combined in an electrical bridge. The first resistance is measures the temperature of the fluid. The second, low resistance, is constantly heated to sustain an expressly specified surplus temperature relative to the temperature of thefluid. Due to the fact that the resistances are inclined directly in the channel, the instrument have splendid dynamics: the response time when changing a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
