| 2 | Drill.5 inch hole in 1 inch PVC cap for the pH sensor |
| 3 | Drill.25 inch hole in 2 inch PVC cap for the temperature sensor |
| 4 | Cut 1 inch slit in 2 inch cap that has the.25 inch hole already for the saline sensor |
| 5 | Drill.25 inch hole in second 1 inch cap for the flow rate sensor |
| 6 | Apply PVC primer to 2 inch PVC male adapter's threading |
| 7 | Apply PVC cement to 2 inch PVC male adapter's threading |
| 8 | Connect 2 inch PVC male adapter to 2 inch PVC flow regulator's flow out threading |
| 9 | Apply PVC Primer to the outside of the ends of the 2 inch 3 sections PVC pipe |
| 10 | Apply PVC Primer to the inside of the ends of the t-pipes and male adapter |
| 11 | Apply PVC cement to the outside of the ends of the 2 inch 3 sections PVC pipe. |
| 12 | Connect 1 section of 2 inch PVC pipe to male adapter. |
| 13 | Connect the 2 inch PVC T-pipe with the 1 inch top into the 2 inch PVC pipe section from step #11 |

| 17 | Apply primer to the inside of the tops of the PVC t-pipe |
| 18 | Apply primer to half of each of the threading section(this will spread when the cap is screwed on) |
| 19 | Apply cement to the same half on each of the threading section |
| 20 | Insert the threading sections into the tops of PVC t-pipes and leave about 2 inches showing |
| 21 | Screw PVC caps to PVC t-pipe threading sections that are showing |
Installation of the Sampling Compartment
| Step Number | Instruction |
|---|---|
| 1 | Insert into plumbing after water tank but before faucet |
| 2 | If needed use an adapter to scale up to the 2 inch sampling compartment |
| 3 | Connect Sampling compartment to existing plumbing in easily accessible and secure location |
| 4 | Apply PVC primer and cement to ends of Sampling compartment |
| 5 | Apply PVC primer to ends of plumbing that are going to be connected to sampling compartment |
| 6 | Screw sampling compartment on to existing plumbing |
Installing the Electronics
| Component | Step Number | Instruction |
|---|---|---|
| Sonar Sensor | 1 | Drill two holes in piece of plywood that is 1 foot by 1 foot in square area |
| 2 | Fasten sensor to plywood with the sonar emitters fitting into the holes | |
| 3 | water proof the sensor by covering the sonar emitters with silicone | |
| 4 | Place the sensor over the IBC tote in a position that the sonar emitters have a clear path to the water, such as over the lid | |
| pH Sensor | 1 | Sensor is water proof |
| 2 | Sensor is integrated into the sampling compartment | |
| 3 | Insert the sensor such that the cable coming out and going away from the sensor and the PVC pipe | |
| Electrical Conductivity Sensor | 1 | The sensor must first be water proofed above the actual sensing strip, which is the black metal section with vertical lines on it, with silicone resin |
| 2 | Sensor is integrated into the sampling compartment | |
| 3 | Insert the sensor such that the cable coming out and going away from the sensor and the PVC pipe | |
| Temperature Sensor | 1 | Sensor is water proof |
| 2 | Sensor is integrated into the sampling compartment | |
| 3 | Insert the sensor such that the cable coming out and going away from the sensor and the PVC pipe | |
| Flow Rate Sensors | 1 | These sensor are water proof |
| 2 | One meter is set at the inlet of the storage tank | |
| 3 | Connect by scaling down the piping if necessary, the sensor has a 0.5 inch diameter | |
| 4 | Screw the sensor into the piping | |
| 5 | Second meter is set at the outlet of the storage tank | |
| 6 | Connect the second flow rate sensor by applying PVC primer and cement to the threads of the flow sensor | |
| 7 | Screw sensor into the on board.5 inch water pump | |
| Sensor Shield | 1 | Place on top of the Arduino |
