Claim Text:
1. A gas regulator, which is set between a gas source and a gas appliance, comprising: a valve block including an input gateway, an output gateway, and a pressure reducing chamber, wherein the input gateway communicates with the gas source, and the output gateway communicates with the gas appliance; a membrane provided in the pressure reducing chamber, which divides the pressure reducing chamber into a first sub-chamber and a second sub-chamber, wherein the first sub-chamber communicates the input gateway with the output gateway, and the membrane deforms due to a change of a pressure in the first sub-chamber; a metal coil provided in either the first sub-chamber or the second sub-chamber; a movable member having a magnetic element received in the metal coil, wherein the movable member is connected to the membrane, and is moved relatively to the metal coil when the membrane deforms; a shielding member provided in the first sub-chamber, wherein the shielding member is moved by the membrane to change an output gas flow of the input gateway; and a processor electrically connected to the metal coil, wherein the processor receives an induced emf generated by the metal coil to obtain a gas pressure value of the gas source.
