9 Rigid Probe Installation
NOTE: TLMB probes do not work with an Integra 100™ or 500™
console; even if you are upgrading from an EECO console to an
Integra™ console, a TLMB probe it will not work.
9.1 Adaptor Collar & Riser Cap
A modified adaptor collar and riser cap (OPW Model 62M) is required
for each probe. These collar and riser cap kits are available from
OPW Fuel Management System.
1. Install the modified adaptor collar onto the riser pipe.
2. Next, screw in the OPW-supplied bushing (62 mm) with
the probe into the 3/8-inch NPT hole in the riser cap.
3. After the probe is lowered into the tank, snap the cap into
place.
9.2 Probe Floats
There are three types of floats used with the probes: Product, Water
for Diesel, and Water for Gasoline.
Note that the two types of water floats are NOT interchangeable.
Because diesel is denser than gasoline, the water/diesel floats are
heavier than the water/gasoline floats. If the wrong water float is
installed in a diesel tank, it does not sink through the product to the
water below. As a result, the tank will have unusually high water
measurements and possibly erratic product measurements as the
water float interferes with the product float.
NOTE: Water float assembly for flexible AST probes is only available
for use in 4-inch (10.2 cm) riser installations.
9.3 Multi-drop Installation
The Integra’s internal barrier and optional VSmart Module allows for
the ability to multi-drop the sensors and probes. When using this
installation method, follow the below directions to ensure approved
wiring.
Sensors and probes cannot be multi-dropped from the same I.S.
Channel; therefore, you must run sensors and probes to different
channels on the barrier.
Seal packs are required with all wiring applications in the field.
Weatherproof junction boxes are REQUIRED with ALL I.S. field
connections.
