less pressure and higher temperatures mean more pressure. If the container pressure is too low, not enough gas will flow from the container to the appliances. Container pressure is measured in PSIG (Pounds Per Square Inch Gauge). The table below shows propane vapor pressures at various outside temperatures. Vapor Pressures of LP-Gases Temperature (ºF)
07-09-2020· The primary function of an LPG gas regulator is to reduce the temperature dependent LPG gas bottle pressure from 400-1200kPa down to the required 2.75kPa operating pressure for the gas appliances. Gas bottle pressure varies with temperature but the LPG gas regulator must be able to consistently maintain 2.75kPa.
