Burkert 219809 (00219809)

Mass flow controller

The thermal inline sensor is located directly in the gas stream and therefore achieves very fast response times.

Burkert Type 8626 Mass Flow Controllers are succinct devices that inspection the mass flow rate of gases. They control the set flow velocity nonetheless of obstruction such as pressure drops or temporary 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 that event, 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 joined 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 a clearly defined excess temperature relative to the fluid temperature. Due to the fact that the resistances are situated directly in the channel, the instrument have splendid dynamics: the response time when changing a given or actual value is hundredths of a millisecond. Additionally, the sensor is almost not polluted.
