| Totaliser | 281ee714633b1e8d5d6623bb61936774 | Totaliser block takes the calculated increments from the Liquid Flow Handler block and integrates these into check-summed totals and remainders, maintaining very high resolution over a wide number range. |
| Liquid Flow Handler | ecd270d90c5863c3e1c7589fc72d8ba8 | Liquid Flow Handler generates the high-resolution increments once corrections are applied to the pulse input stream.The block also calculate instantaneous corrected flow rate values for indication purposes. |
