Abstract
The liquid level of a liquid supply compressor including a gas-liquid separator is dynamically monitored. A liquid supply gas compressor includes a compressor body; a gas-liquid separator separates liquid from compressed gas, to store the liquid; a liquid piping system supplies liquid stored to the compressor body; an internal pipe extends in an internal space of the gas-liquid separator, and includes at least two hole portions, with different disposition positions in a height direction, on an internal side to communicate with the piping system; and a sensor detecting pressure or temperature of fluid flowing through the piping system.
