Mass Flow Controllers Type 8626 are compact arrangement that monitoring the mass flow of gases. They command the set flow rate irrespective of obstruction for example pressure drops or interim flow resistance. Flow controllers 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 resist and the measuring resistance are adjusted to a constant temperature differentiation. Both resistances are immediately in the gas stream; and three resistances are out of it. All resistances are joined 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 specified excess temperature relative to the temperature of theliquid. Owing to the reality that the resistances are disposed at once in the channel, the devices have splendid dynamics: the response time when modifying a given or actual value is hundredths of a millisecond. In addition, the sensor is almost not contaminated.
