Abstract
A method of operating a sealing monitoring system for a seal of a rotatable shaft including a flushing liquid system, the seal disposed between the rotatable shaft and a stationary housing. The sealing monitoring system includes a liquid detector to detect a presence of a flushing liquid in the flushing liquid system. The method includes detecting the flushing liquid presence status in the flushing liquid system with the liquid detector, and when the flushing liquid presence status is affirmative, transmitting the flushing liquid presence status for processing using a wireless data communication system with a first data transmission interval between the transmissions, and when the flushing liquid presence status is negative, transmitting the flushing liquid presence status for processing using the wireless data communication system with a second data transmission interval being shorter than the first transmission interval between the transmissions.
