P0060.1

Tank pressure evolution

P0060.1 product shows the timeseries of site's tanks pressure. There is one plot box by tanks' type (Target short term, calibration, etc.). Each tank has its own color. Theoretical pressure drop, based on a gas flow between 150 and 200 mL/min (grey ribbon) or measured flow (black line, if available) is also displayed in order to be able to compare real pressure drop to expected pressure drop.

Details:

• Data used: Tank pressure measurements.
• Y-axis: Pressure in bar.
• Timeframe: all available data, i.e. time frame with available tank pressure.
• Colored point: In a given plot box, one color per tank, one point per pressure measurement.
• Grey ribbon: expected pressure drop for a gas flow between 150 and 200 mL/min. The amount of minute of use is extracted from real tank measure data.
• Black line: expected pressure drop for a gas flow as measured by digital flowmeter, if available.
• Red horizontal line: 30 bar. Pressure at which the tanks should be replaced.
• Legend on the right: Tank name. If the tank is still connected and have at least 4 pressure measurement since last configuration change, the date when the pressure is expected to be at 30 bar is also writen.
