LEVEL GAUGING
Selecting which level
gauging technology to
employ will be wholly
dependent on the application
requirements and regulatory
bodies. However, all the
leading manufacturers of tank
gauges and systems
emphasise that it's imperative
to determine at the outset
what information is required,
how it is to be presented and
finally how it is interpreted.
Both Enraf and Varec define
tank gauging as the generic
name for static quantity
assessment of liquid products
in bulk storage tanks. Tank
gauging is essential for the
assessment of tank contents,
tank inventory control and
tank farm management.
Enraf states that level
uncertainties of only 1mm in
a 10m tall, 50,000m³ tank
equates to 5 m³, clearly
indicating that accurate
measurement is the prime
requisite for good inventory
management. However, it is
still only one of the many
aspects involved in tank
gauging. Reliability to prevent
product loss, performance to
optimise product movements
and safety to protect the
environment and personnel
are issues that are of
equal importance.
