Figure 8-5 Logger
Measurement Line

It is recommended that the LevelVent or AquaVent logger be installed in a vertical orientation. However, inclined or horizontal installation is acceptable.

The pressure sensor measurement line is indicated by the machined line around the logger body, just above the pressure access holes (Figure 8-5).

The pressure transducer is oriented in a plane normal to the long axis of the body, and detects pressure directed along the plane of the long axis. In vertical orientations, the sensor detects pressure above the pressure transducer line. In non-vertical orientations, the pressure zero point is proportional to the angle of inclination.
