Electronic gas separator
Patented electronic gas separator
FlowCheck continuously monitors the presence of
gas in a delivery of petroleum products from road
tankers with volumetric meters. Upon discovery of
gas, the delivery is stopped immediately and gas
separation commences automatically through a
pneumatically controlled gas outlet unit.
Fast and accurate deliveries
FlowCheck is approved to OIML R117 standards up
to a flow rate of 1300 litres per minute. The
exceptionally low pressure drop of FlowCheck allows
a substantially higher flow rate, with retained
measurement accuracy, compared with traditional
gas separators thus making the actual discharge time
much shorter.
No product contamination
FlowCheck is designed to be completely empty after
delivery, leaving no residues, thereby avoiding
contamination.
Widely spread
The first version of FlowCheck was introduced in the
Swedish market in 1991. Since then the development
of the product in terms of functionality and
simplification of installation has made it popular and
widely spread. There are now more than 2000
installations of FlowCheck on road tankers in:
- Belgium
- Denmark
- Finland
- Holland
- Ireland
- Norway
- South Africa
- Sweden
- U.K.
Flexibility
FlowCheck can be installed together with traditional
PD-meters but it´s laminar flow makes it specially
suitable for turbine meters. The sensor can be
integrated with electrical metering systems thereby
offering features like pre-set and interlock. The
programmable logic of the sensor can be upgraded
to satisfy future changes in regulations and demands.
Another possibility is to apply the FlowCheck principle
on other non-leading liquids.
Logically controlled outputs
FlowCheck enables up to three different outputs to
be logically controlled by the sensor giving possibilities
of simplifying the total installation of a metering kit.
Basic features
- No moving parts
- Insensitive to dirt
- Low weight
- Small dimensions give a neat and simple installation
- Negligible contamination
- Negligible pressure drop resulting in quick and economical deliveries
- A delivery can easily be started regardless of compartment levels
- Can be integrated with the meter volume pre-set function
- Quick-start feature enabling fast filling of empty pipe system
- Enables conditional or logical control of a delivery pump or a vacuum breaker
- Eliminates the need for an "aircheck" valve after the meter since an empty FlowCheck sensor will keep the stop valve closed
- Full pump meter after delivery
- Allows full or empty gravity meter after delivery
- Can react to diffused air in the delivery (foam detect)
- Works with petroleum-based products
- Environmentally sound since it can be installed as a closed system (VOC)
- Intrinsically safe and Ex-approved
Working principle
The sensor (FCS) monitors the product flow ahead of
the meter and if any gas is detected it will close the
pneumatic ball valve (FCV), fitted after the meter.
Gas will then be led through the riser tube to the
gas outlet unit, (FCAU). When the sensor activates
degassing it also opens the gas outlet unit and the
system pressure will push gas out of the unit. The
gas can be led to the vapour return system or via a
by-pass to the outlet of the delivery hose.
