Burkert Type 8626 Mass Flow Controllers are compact devices that monitoring the mass flow rate of gases. They control the set flow velocity regardless of obstruction for example pressure loss or provisional resistance to flow. Flow controllers consist of a flow meter, an electronic module, and a proportional valve. Inline sensors function in the constant temperature anemometers mode. In this case, the electrical heating resistance and the measuring resistance are set to a constant temperature difference. Both resistances are immediately in the gas stream; and three resistances are out of it. 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 defined surplus temperature relative to the temperature of theliquid. Due to the reality that the resistances are located directly in the channel, the devices have superb dynamics: the response time when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not contaminated.
