DENSITY MEASUREMENT
FLOAT KITS
With density float kits, EVOTM Series fuel management systems have the
ability to continuously monitor the density of fuel stored in underground
and aboveground storage tanks. The same magnetostrictive probe that
provides inventory management and leak detection capabilities can also
supply product density and mass without the addition of extra probes or
sensors. Programmable high and low density alarm points allow the user
to determine the range of acceptable density fluctuations.
HIGHLIGHTS
SPECIFICATIONS
•
•
•
•
Designed for applications involving 4" riser pipes.
•
Water and product floats are coloured red for gasoline and
blue for diesel.
•
•
•
•
•
•
Density and product floats are calibrated and must be
maintained as a set.
•
Theory of Operation: Density measurement is based on the
distance between the calibrated product and density floats.
As the density of the fuel changes, the gap between the floats
will increase or decrease in proportion to the change. The
tank gauge receives this information from the probe and uses
it to calculate and display the current density of the fuel.
Each float set contains a product, density, and water float.
Floats are constructed of Nitrile rubber and PVDF (precision
model density floats are also nickel-plated).
