The most popular accessory McTighe offers is the high oil level alarm. The internal oil storage capabilities of our oil-water separators make this option a smart choice for indicating single or multiple oil storage levels. The system consists of a level sensor and an alarm control panel.

The level sensor will detect the oil-water interface and send a signal to the control panel that typically includes a visual alarm and audible alarm with silencer.

Oil removal, after the alarm has activated, is typically performed with a self-priming pump by removing the access manway cover and lowering a suction hose into the oil layer. Remove oil until the layer is sufficiently reduced. Refill separator with water after oil removal.

As an option, McTighe has configured a special arrangement to prevent water from being transferred to storage after the oil alarm sounds. The McTighe Basket Stop consists of an oil suction pipe (typically 4") with an end that prevents suction hose passage. After the alarm activates, simply drop a suction hose down the 4" pipe and turn on the pump. Refill the separator with water after oil removal.

The drawing below shows a standard high oil alarm system and include a detail of the optional Basket Stop.
