6. Usage
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.

Here, the inner diameter of the bypass tube which is connected to the D6F-PH is 4[mm]
and its length is 800[mm] or less.
