Method of operating a sealing monitoring system and a sealing monitoring system for a seal

A sealing monitoring system for a seal in an apparatus comprising a rotatable shaft, a flushing liquid system, the seal being arranged between the rotatable shaft and a housing, the sealing monitoring system comprising:

• a liquid detector configured to detect presence of a flushing liquid in the flushing liquid system;
• a data processing apparatus configured to receive data of the liquid detector;
• and
• a wireless data communication system in data transfer connection with the data processing apparatus,
• the data processing apparatus comprising
• executable instructions to detect a flushing liquid presence status of the flushing liquid system,
• executable instructions to determine a first flushing liquid presence status to be either affirmative when the presence of the flushing liquid in the flushing liquid system is detected, or negative when the presence of the flushing liquid in the flushing liquid system is not detected,
• the data processing apparatus further comprising
• executable instructions to transmit the flushing liquid presence status intermittently for processing, at least one of a first data transmission interval or a second data transmission interval occurring between transmissions of the transmitting the flushing liquid presence status intermittently,
• the executable instructions to transmit the flushing liquid presence status includes transmitting the flushing liquid presence status for processing using the wireless data communication system with the first data transmission interval when the flushing liquid presence status is affirmative, and
• the executable instructions to transmit the flushing liquid presence status includes transmitting the flushing liquid presence status for processing using the wireless data communication system with the second data transmission interval, which is shorter than the first data transmission interval between the transmissions, when the flushing liquid presence status is negative.
