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).

Columns of the series — Scenario 1 — Filling

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.

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).

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.

Limits of this data

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)
