Burkert 230330 (00230330) Mass flow controller
- Alternative numbers
The thermal inline sensor is located directly in the gas stream and therefore achieves very fast response times.

Mass Flow Controllers Type 8626 are compact devices that monitoring the mass flow of gases. They regulation the set flow velocity irrespective of interference including drop in pressure or provisional resistance to flow. Flow controllers consist of a flow meter, an electronic module, and a proportional valve. Inline sensors work in the CTA mode (constant temperature anemometers). In this case, the electrical heating resistance and the measuring resistance are adjusted 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 electrical bridge. The first resistance in the fluid flow measures the temperature of the liquid. The second, low resistance, is constantly heated to maintain a clearly specified excess temperature relative to the temperature of thefluid. Due to the reality that the resistances are disposed 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 practically not polluted.
