6-1. Recommended tube connection method of D6F-PH

When connecting the D6F-PH sensor in a bypass configuration, the sensor is able to
detect fine pressure changes. This is achieved by providing an orifice in the main channel,
which generates a small pressure change before and after the orifice. The D6F-PH will be
connected to the bypass flow path from the pressure port which is provided before and after
the orifice.
