The pressure regulator does not measure consumption, but it is critical for ensuring that gas reaches consumers at a stable and safe pressure.
What the regulator does
It reduces higher inlet pressure to a lower outlet pressure and attempts to keep it stable as the flow changes.
What happens when consumption increases
The regulator opens further to allow a larger amount of gas to pass through.
Limited capacity
If the required flow exceeds its capacity, the downstream pressure may drop.
Correct selection
The regulator is selected based on inlet pressure, outlet pressure, maximum flow, and operating characteristics.
