Systems and methods for flash tank liquid level control are provided. A flash tank is a device used to separate the vapor and liquid phases of a mixture. Maintaining a desired liquid level may be important. If the flash tank overflows, liquid injected into the compressor may potentially damage the compressor. If the flash tank drains out of liquid completely, two-phase refrigerant may then be provided being into a lower expansion value, which will impact its operation. To maintain the liquid level within the flash tank within the desired range of values, a pressure sensor may be provided to measure either a pressure differential or absolute pressure of the liquid refrigerant. This measurement may then be used to calculate the liquid level within the flash tank. A controller may then send control signals to an electronic expansion valve provided between a condenser and the flash tank to either open or close depending on the liquid level within the flash tank.
