GAS REGULATOR

There is provided an actuator system for adjusting gas flow through a gas regulator, said actuator system comprising; at least one sensor for sensing a property, such as gas pressure or gas flow, and based on said property generate a sensor signal; an actuating means with a moving part adapted to be arranged in connection with the gas regulator; and a control unit adapted to receive said sensor signal from the sensor, and based on said sensor signal send an instruction signal to the actuating means for changing a position of said moving part. There is also provided gas regulator system and a method for dynamically controlling a flow of gas in a gas regulator.
