Burkert 274528 (00274528)

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 (MFC) are succinct devices that inspection the mass flow of gases. They command the set flow rate nonetheless of interference for instance pressure loss or interim flow resistance. Flow controllers include a flow meter, an electronic module, as well as a proportional valve. Inline sensors operate in the CTA mode (constant temperature anemometers). In that event, the electrical thermal resist and the measuring resistance are set to a constant temperature differentiation. Either resistances are immediately in the gas stream; and three resistances are out of it. All resistances are united in an electric bridge. The first resistance is measures the temperature of the liquid. The second, low resistance, is constantly heated to sustain an expressly defined surplus temperature relative to the temperature of theliquid. Owing to the fact that the resistances are located straight away in the channel, the apparatus have excellent dynamics: the response time when altering a given or actual value is hundredths of a millisecond. Additionally, the sensor is practically not polluted.
