  • Excessive gas flow detector
    Patent number: 4668943
    Abstract: An excessive gas flow detector has a probe in which an electrode and immediately surrounding part of an insulating sleeve are protected by a shielding ring surrounding the electrode from direct impingement of spray carried by gas sweeping down into a well under excessive gas flow conditions. A test unit for plugging into a socket of the detector gives an indication on light emitting diodes of whether there is an excessive or normal gas flow through the detector.
