Mass Flow Controllers Type 8626 are succinct arrangement that inspection the mass flow of gases. They command the set flow rate nonetheless of interference including pressure drops or temporary resistance to flow. Flow controllers consist of a flow meter, an electronic module, as well as 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 difference. Both resistances are immediately in the gas stream; three more resistances are outside him. All resistances are united in an electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is heated continuously to sustain an expressly specified surplus temperature relative to the fluid temperature. Due to the reality that the resistances are located straight away in the channel, the devices have excellent dynamics: the time for reaction when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not polluted.
