Mass Flow Controllers Type 8626 are compact devices that monitoring the mass flow rate of gases. They regulation the set flow velocity oblivious of hurdle for example pressure drops or provisional flow resistance. Flow controllers include 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; and three resistances are out of it. All resistances are combined 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 theliquid. Owing to the fact that the resistances are located at once in the channel, the instrument have excellent dynamics: the response time when altering a given or actual value is hundredths of a millisecond. In addition, the sensor is practically not polluted.
