Leak detection Hysteresis
Leak detection Hysteresis

Reviewing my data in OSCAR, I noticed that the "Large leak" detection suffers from small signal variation around the level were it is triggered (see attached graph). To avoid this, in industrial applications were we need to reliably turn things on or off based on an analog signal that has noise (just like the leak rate and the Large leak detection) we use Hysteresis.

This means like: Turn "on" the large leak flag when reaching 24l/min and turn it off when it is lower than, let's say, 20 l/min. So you won't get this on-off effect on the beginning and end of the large leak.

It is just a suggestion of a detail to improve OSCAR even further.
