Let's assume for the moment that we have a main LP regulator that puts out exactly 11 in. WC with an unlimited flow rate potential (ideal).... just to put pipe diameter and other constraints out of the equation.
On the other end of the line is an LP appliance, a generator, that has a demand regulator and with the load block set to sustain the genny up to 100% full load.
Given that the demand regulator responds to engine vacuum (or lack of), does it also work to regulate the flow rate that's fed into the combustion chamber depending on the engine load?
Another way to put it, so if the load block was tuned to sustain the engine at 100% load, there's a certain flow rate associated with it. What happens to the flow rate when the engine ramps down to say, 75% load or 50% load.... does the flow rate:
a) Go down, or
b) Remain constant (as per load block setting)?
The thing I'm getting at is LP fuel consumption. Will a generator consume less LP when it is partially loaded VS fully loaded?
