Chemical Usage Measuring
Verify titration of chemicals before proceeding
1. Setup lab scale with small bucket of chemical to be measured.
2. Put the suction line into the bucket.
3. Run the application being tested to “prime” the line. (All air bubbles must be removed for accuracy)
4. Record the Initial Weight from the scale. (Tarring the scale with weight on the scale can affect accuracy)
5. Run the application for 6 vehicles (or manually for the same it would be on for 6 vehicles).
6. Record the Final Weight from the scale.
7. Subtract the Initial Weight from the Final Weight to determine the weight of used product.
8. Divide this Used Weight by 6 to get a per car weight.
9. Divide the Per Car Weight in grams by the specific gravity of the chemical to determine the milliliters of chemical
used per vehicle.
10. Repeat for each chemical application.
