SENSORS
No matter what the monitoring application is, Franklin Fueling Systems offers a sensor solution tailored to the specific requirements of each application.
SENSOR SELECTION GUIDE
Does your application require the need to tell the difference between fuel and water?
Discriminating Sensors are able to detect and send an alarm signal if the presence of liquid is detected inside and can also differentiate between liquid and hydrocarbons.
Does your application only require the need detect any type of liquid?
Non-Discriminating Sensors are able to detect and send an alarm signal if the presence of liquid is detected inside of a containment space.
What type of Automatic Tank Gauge (ATG) are you connecting to?
