How does a gas meter regulator work?

A pressure regulator’s primary function is to match the flow of gas through the regulator to the demand for gas placed upon it, whilst maintaining a constant output pressure. The measuring element functions to determine when the inlet flow is equal to the outlet flow.Click to see full answer. Moreover, how does a gas regulator work?A pressure regulator works through the same principles of any natural gas regulator. When pressurized natural gas enters the regulator, it will push up against the diaphragm, bringing tension to the spring. The diaphragm will move upward as far as the tension of the spring will allow it to go.Subsequently, question is, what is the purpose of a natural gas regulator? A natural gas regulator receives external gas from a line under very high pressure. It plays an important role in the safety of the people operating it, may it be in an industrial (furnace, gas engines and boilers) or commercial purpose (natural gas appliance). In this way, what happens when a gas regulator fails? In general, regulator failure would result in either too much or too little pressure downstream. If the regulator fails and allows too much gas to flow (a “failed-open” condition for the regulator), downstream pressure will increase. The relief valve will remain closed until pressure reaches its set point.Are all gas regulators the same?Although the purpose of LPG regulators is the same, different applications may require different types of regulators. The gas demand of the appliances determines what type of regulator is installed. Commercial sized regulators are completely different and frequently comprised of two separate units.
