The OilTector
®
control system is designed and approved for safe operation of pumping, alarming and monitoring of elevator sump pits,
transformer vaults and other applications where oil and water must be detected. The OilTector
®
system will activate the pump to remove
water from elevator pits in accordance with ASME A17.1, and will provide pumping of only water - even if an oil condition is detected.
The OilTector
®
cycles the pump only in the water range. Oil and other harmful substances are not discharged into the environment.
An alarm is activated in the event of a high water condition or high oil condition.
OilTector
®
Description of Operation
On water rise, the pump will activate when the water level
reaches the “start” probe. Pump will remain on until the
water level is below the
“off” probe. When the “off” probe
no longer senses water it turns the pump off, air or oil are
ignored and an oil layer (if present) will not be pumped out
of the sump. If the liquid level reaches the “alarm” probe and
mechanical float, the system will differentiate between water
and oil and activate the appropriate alarm
.
