Sand Slurry Flow Monitoring
NonContacting
Sensor works
from Outside
the Pipe
CanFrac Sands Ltd. of
Lloydmister
Saskatchewan
(Canada) needed a
owmeter that could
accurately measure
sand slurry ow
without being
damaged by this
highly abrasive
product. ey selected
the Greyline DFM 5.0
Doppler Flow Meter
with a clamp-on
ultrasonic sensor
mounted on the
outside of a pipe.
CanFrac produce “fracturing sand” used by the oil
and gas industry. is special type of sand is
pumped into an oil or gas well to help keep
fractures between layers of rock propped open to
allow hydrocarbons to ow to the wellbore.
CanFrac consulted Tarpon Energy Services of
Calgary, Alberta for solutions when their inline
owmeters were damaged by the abrasive sand.
Tarpon proposed the Greyline DFM 5.0 Doppler
Flowmeter.
In this application a mixture of recycled water and
frac sand is pumped at 1600 gpm (2 m/sec
velocity) through a 10” carbon steel pipe.
CanFrac use the owmeter's digital display to
monitor ow rates and take daily readings from
the meter's built-in totalizer.
Greyline Doppler Flow Meters and Flow Switches
are ideal to measure ow of “difficult” liquids
including mining slurries, wastewater and aerated
liquids. For complete information visit
