The level will appear higher than the ML selected because of added powder volume/density and/or variance in bottle making. Example: 120ml of water plus powder volume is approximately 135ml depending on your formula powder type.
If you wish to check the Formula Pro Mini is dispensing the correct amount of water you can test this by running the “water only” function. The most accurate way of testing the water is by weighing it (1ml of water will weigh 1g).
There is a tolerance of water level. Provided the water weighs within the final yield for the amount of water dispensed, then your machine is working correctly.
| ml selected | final yield |
| 60ml | 57.3 - 60.9ml |
| 90ml | 86ml - 91.4ml |
| 120ml | 114.8ml - 121.8ml |
| 150ml | 143.5ml - 152.3ml |
| 180ml | 172.1ml - 182.7ml |
| 210ml | 200.8ml - 213.2ml |
| 240ml | 229.5ml - 243.7ml |
| 270ml | 258.2ml - 274.2ml |
| 300ml | 286.5ml - 304.6ml |
