Gas turbine compressor water wash control of drain water purge and sensing of rinse and wash completion

A rinse cycle sensor apparatus to indicate to an operator completion of a washing operation, the apparatus comprising:

• a conductivity sensor that measures the conductivity of fluid as the fluid exits a device being washed;
• and
• a transmitter coupled to the conductivity sensor to receive conductivity measurements from the conductivity sensor and to transmit the conductivity measurements to a computer system for processing,
• wherein the conductivity sensor and the transmitter are disposed within a wash system to obtain conductivity measurements of wash fluid as the wash fluid exits the device being washed.

A method for completing a rinse cycle of a device, the method comprising:

• providing a rinse cycle sensor apparatus, comprising:
• a conductivity sensor that measures the conductivity of fluid as the fluid exits the device being washed;
• and
• a transmitter coupled to the conductivity sensor to receive conductivity measurements from the conductivity sensor and to transmit the conductivity measurements to a computer system for processing;
• attaching the rinse cycle sensor apparatus within a drain line of the device being washed to obtain the conductivity measurements of fluid as the fluid exits the device being washed;
• receiving the conductivity measurements of the exited fluid;
• and
• analyzing the conductivity measurements of the exited fluid against preset conditions.
