This portion is part of a larger tutorial to set up a sample laboratory process of adding chemical to a tank and the start of which can be found here.
Before starting this tutorial, plumb your large tank to ensure that it can drain to the sink.
...
Find a 7 kPa pressure sensor and plug it into the Sensor Box. Note the location of sensor by the number.

Step Two: Add the Pressure Sensor to the Experiment
Plug the pressure sensor into the tank at the bottom. Fit a 0.25" O.D. inflexible tubing over the end of the pressure sensor that should be in contact with the water as shown in the picture below.

Step Three: Open Appropriate Sensor Calibration File in Process Controller
...
The next step is to zero the pressure sensor. With the tank fully drained of water, "zero" the sensor. The pressure reading should be close to zero.
Next add about 2 L of water to the larger tank. The pressure sensor should now read a water height of approximately 3.5 cm. Confirm this.
