Also in another post on this website a person was using multiple PID loops. In the industry this is referred to as Cascade Control. So, you could measure out the feed water fill rate (cold water coming in) against the steam output. With the relatively small boiler size this control method could be h...

PID Control can compensate to detect a small variation of water being introduced to a boiler and start the heating element BEFORE the water would get cold. However, this is mostly a slippery slope of trying to introduce derivative (the D of PID). So, even though PID was thought up years ago does not...

The PENN (FYI: JOHNSON) pressurestat has a setting and a DIFFERENTIAL. Don't worry about how it looks. Keep in mind you have the two settings to deal with. In the heating industry they sometimes call this differential deadband. What it means is that you set it for a value e.g. 1.5. Then, you set a d...
