Be aware that the new version v49.0 will not work with previous versions. Users need to backup their records and uninstall the existing app before updating to v49.0.
*******************************************

Drop Test is an app to calibrate/measure the chemical dosing pump output. It is intended to be used in a water and wastewater treatment process. This app was developed for personal use only but anyone working in a similar field are free to use this app. Make sure that you double check the results.

How it works:
- There are pre-loaded chemicals and pump numbers that you can edit to suit your application. You need to find out the specific gravity and concentration of your chemicals to calculate the Yield. You'll find these info from the chemical delivery dockets.
- The chemical yield is Specific gravity x concentration. SG x Conc (%w/w)
- When everything is filled-in, the calculated dosage will be displayed automatically as soon as you tap "Stop" button.

The dosage is calculated as follows:
Volume dropped(Liters) x Yield x 24 x 60
divided by:
Plant Flow (ML/d) x Time (min)

which gives results in mg/L.

*** NOTES***
- Whe drop testing fluoride, this app only calculate the fluoride solution dosage and not the actual fluoride ions. If fluoride ions is desired, just multiply the results by 0.7911

- When drop testing more than one pump, make sure you have enough chemicals in your drop test cylinder. You don't want your pump to run dry!!!

- Make sure you hit Save to keep records of your drop test.

- In the report, Yield means S.G x Concentration.
