Leak detection system |
摘要 |
Leakage from a gasoline storage tank or other receptacle is detected by differentiating the output from a liquid-level monitoring transmitter with stepped voltage output and applying the differentiated transmitter signal through an amplifier to a latch controlled relay for activating an alarm. An interlock circuit is provided for deenergizing the detector part of the system whenever the contents of the tank is being altered intentionally.
