Burkert Type 8626 Mass Flow Controllers (MFC) are compact devices that control the mass flow rate of gases. They regulation the set flow rate irrespective of obstruction for instance drop in pressure or interim flow resistance. Flow regulator include a flow meter, an electronic module, as well as a proportional valve. Inline sensors work in the constant temperature anemometers mode. In this case, the electrical heating resistance and the measuring resistance are adjusted to a constant temperature differentiation. Either resistances are directly in the gas stream; and three resistances are out of it. All resistances are joined in an electrical bridge. The first resistance is gauge the temperature of the fluid. The second, low resistance, is constantly heated to maintain an expressly defined excess temperature relative to the temperature of thefluid. Due to the fact that the resistances are disposed straight away in the channel, the devices have splendid dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not contaminated.
