Instrotech is offering the Kobold DOG range of flowmeters that use the unique oscillation principle to measure dry or humid gases even in low pressure applications. In this measuring procedure, a partial stream of the medium is led into the measuring cell by means of a bypass. In the measuring cell, the medium flows through a chamber with two flow channels. A gate allows the stream to flow through either the left or the right channel. The flow creates over-pressure on one side and under-pressure on the other. The difference in pressure directs the media stream to the other side. This results in the stream between the two sides oscillating, which sets the medium in the connecting channel into vibration. The frequency of the oscillation is directly proportional to the flow speed. A detector determines the oscillation in the connecting channel and converts it into an electrical signal. The signal is processed further in the downstream electronic unit and then displayed or output in another form.
