Transient gas pressure issues (non boosted and boosted) can be experienced on low pressure systems operating at 21 mbar notional gas pressure.
The start up of a gas appliance (or significant load change) can cause the inlet gas pressure to dip momentarily BELOW 21 mbar , in extreme cases causing the appliances “under-pressure cut off switch” to shut off before gas pressure recovers via the gas meter/gas network back to 21 mbar. This is your classic nuisance “trip”.
This is a “control issue” and by slowing down/removing the sensitivity of the client booster/appliance take-off should mitigate/solves the issue. The Clients pipe designer (meter to appliance) should therefore keep in mind to cater** for possible the momentary (transient) pressure dip to prevent nuisance trips of his gas appliances.
Note this pressure dip may be exacerbated if a rotary positive displacement gas meter (“rotary” gas meter) is used which can take a second or two to fully respond (the rotors need to spin up) – and the pressure regulator on the meter takes a second or so to open fully (as evidenced in the video).
