14.1.15 Installing the 30-3225
See the Local and National Electrical Codes for your location. Make sure that
the cabling leading back to the controller (gas/oil resistant Petro Vend number
12-1030) is installed in conduit dedicated to intrinsically safe wiring.
NOTE: Hydrocarbons float on water – If this sensor is fully submerged, the polymer will NOT detect
hydrocarbon liquid.
• This sensor requires two (2) Controller Interface Module position
• Review the Connections table and the Typical Installation drawing below
• Use the supplied cable gland and silicon wire nuts
• Install seal-offs at both ends of the conduit run
NOTE: For normally dry wells, use a meter to orient the Dual-Level Float portion of the sensor so the sensor
is in the closed state with NO liquid present (float in lower position). For normally wet well, orient the float so
that it is in the closed state WITH liquid present (float in upper position).
Only three wires are required to connect the sensor to the Controller positions. Use one wire as the common
power connection to each sensor (red wires). The other two wires bring each sensor’s data back to the
separate controller data terminals.
