Data series · Chapter 10
Scenario 1 — Filling
Inflow via Y1 and Y2, expected rise 2.55 l/s. Measurement: 2.551 l/s, B1 reports at 136.5 s.
Time series
Each quantity has its own axis and unit in its own panel; all share the time axis. The sensor bits appear as step lines. Clicking the legend shows or hides a quantity.

Column description
Name and unit come from the header row of the CSV file; the meaning follows the heated-tank model (chapter 8) and the recording (chapter 10).
| No. | Column (CSV header) | Unit | Type | Meaning |
|---|---|---|---|---|
| 1 | Zeit (s) | s | Time axis | Time stamp of the row (model time); one row per calculation step of Δt = 0.05 s. |
| 2 | Füllstand (l) | l | Process variable | Water level in the tank (tank volume 0.5 m³ = 500 l). |
| 3 | Temperatur (°C) | °C | Process variable | Water temperature, calculated from energy and water mass. |
| 4 | Druck (bar) | bar | Process variable | Pressure in the head space (steam and air, partial pressures added). |
| 5 | Heizleistung (W) | W | Process variable | Currently effective heating power (PT1 lag, τ = 12 s, up to 150 kW). |
| 6 | B1 Füllstand max | — | Sensor bit (0/1) | Upper level sensor: 1 from 450 l, otherwise 0. |
| 7 | B2 Füllstand min | — | Sensor bit (0/1) | Lower level sensor: 1 at 50 l or less, otherwise 0. |
| 8 | B3 Temperatur ≥95 °C | — | Sensor bit (0/1) | Temperature sensor: 1 from 95 °C, otherwise 0. |
| 9 | B4 Druck ≥2,8 bar | — | Sensor bit (0/1) | Pressure sensor: 1 from 2.8 bar, otherwise 0. |
Statistics of the series
All figures are computed from the rows of the CSV file (over the whole series, without smoothing) and describe this single run only. They make no statement about a real tank.
| Quantity | Unit | Count | Minimum | Maximum | Mean | First value | Last value |
|---|---|---|---|---|---|---|---|
| Füllstand | l | 3,000 | 101.96t = 0.05 s | 484.49t = 150.00 s | 293.227 | 101.96 | 484.49 |
| Temperatur | °C | 3,000 | 16.051t = 149.95 s | 19.994t = 0.05 s | 17.0748 | 19.994 | 16.051 |
| Druck | bar | 3,000 | 0.0000t = 148.35 s | 0.0099t = 141.60 s | 0.0094 | 0.0081 | 0.0000 |
| Heizleistung | W | 3,000 | 0.0constant | 0.0 | 0.00 | 0.0 | 0.0 |
Below each extreme value is the time of the first row with that value. The mean is the simple mean over all rows (equal time steps).
| Sensor bit | Rows with 1 | Share | first 1 at | then 0 again at | Changes |
|---|---|---|---|---|---|
| B1 Füllstand max | 271 | 9.033 % | 136.50 s | — | 1 |
| B2 Füllstand min | 0 | 0.000 % | — | — | 0 |
| B3 Temperatur ≥95 °C | 0 | 0.000 % | — | — | 0 |
| B4 Druck ≥2,8 bar | 0 | 0.000 % | — | — | 0 |
1 means the sensor is active (threshold reached), 0 not active (chapter 8). “Changes” counts the rows in which the value differs from the previous row.
Values
All rows of the CSV file, unchanged, 100 rows per page. Search and sorting run on the server; you can jump to a row or a time. “No.” is a running row number and not part of the CSV.

- Classification (chapter 10): Direction and order of magnitude agree; B1 switches when 450 l is reached.
- The expected values come from hand calculation and the analytical solution with the parameters of the model; agreement shows the correct implementation, not the accuracy compared with a real tank. Each scenario covers a single run with fixed boundary conditions. (Chapter 10)
- Without measurement data from a real tank, validation is limited to internal consistency. (Chapter 11)
