DIAGNOSTIC SIGNAL TO ANNUNCIATE PRIMARY SEAL FAILURE IN A LEVEL TRANSMITTER |
摘要 |
A method and system for seal failure annunciation comprises a process connector connected to a probe used to measure a product level in a tank. A pulse generation module generates a pulse that is propagated through a voided space in the process connector and a detector module configured to receive the echo curve from the interrogation pulse. A logic module is used to evaluate the received echo curve to determine if a seal in the process connector has failed. When the logic module indicates seal failure, an alarm module initiates an alarm indicating said seal in said process connector has failed. |
