Mass Flow Controllers Type 8626 are compact arrangement that inspection the mass flow of gases. They regulation the set flow velocity irrespective of obstruction for example drop in pressure or interim resistance to flow. Flow controllers include a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In this case, the electrical heating resistance and the measuring resistance are set to a constant temperature differentiation. Either resistances are directly in the gas stream; and three resistances are out of it. 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 an expressly defined excess temperature relative to the liquid temperature. Due to the fact that the resistances are situated straight away in the channel, the apparatus have superb dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not contaminated.
