Mass Flow Controllers Type 8626 are succinct arrangement that inspection the mass flow of gases. They regulation the set flow velocity oblivious of interference for instance drop in pressure or interim flow resistance. Flow regulator consist of a flow meter, an electronic module, and a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). In this case, the electrical thermal resist and the measuring resistance are adjusted to a constant temperature differentiation. Either 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 constantly heated to maintain a clearly defined excess temperature relative to the temperature of thefluid. Owing to the fact that the resistances are situated at once in the channel, the devices have excellent dynamics: the response time when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
