12 Installation with Existing OPW/EECO
Equipment
12.1 Model 924A Probes
CANNOT BE MULTI-DROPPED ON VSmart.
The Model 924A Probe (Figure 12-1) utilizes magnetostrictive
technology to derive accurate product and water levels. It is primarily
used in underground storage tanks for inventory and leak detection.
Two floats can be fitted to the probe shaft; the product float sits on top
of the product and the water float (optional) sinks through the product
and sits on top of the water at the bottom of the tank.

Five temperature sensors reside in the probe shaft for measuring
product temperature at different levels in the tank. They are located at
positions of approximately 20%, 40%, 60% and 80% of the tank’s
volume. The sensors feed the data of the temperature of the fuel to
the console. The console software is then able to make the
calculations to produce a net corrected product volume.
