3-4 : How to use the Dummy detector
The measurable flow rate can be doubled, tripled, or quadrupled by installing 1,2,3
dummy detectors, respectively. A detector must be combined with dummy detectors
of the similar shape. If the flow rate is to be increased in future, the measurable
range can be expanded easily by installing a model with an elbow flange. (with a
cover).
