Metering System
The metering system provides an accurate and calibrated
means for measuring the amount of product dispensed from
the Orca tank to the customer. The system is made up of five
components: the Meter Section, two Differential Pressure
Transmitters, Resistance Temperature Device and the
Flowcom

Flow Meter System
Meter Section
The Orca system incorporates an Orifice type meter section,
which unlike turbine meters, has no moving parts to wear
out or be damaged by gas This unique feature makes the
meter section a low maintenance item. As the liquid flows
to the tapered orifice, a high pressure zone is created. Once
the liquid flows through this restriction and reaches the
larger “back side” of the restricted orifice, a drop in pressure
occurs. This difference of pressure is the beginning of how
product is metered A 1/4” (6mm) line is plumbed into each
side of the meter section These two lines are then plumbed
to the Differential Pressure Transmitters which make this
differential pressure an electronic signal.
