CanFrac Sands Ltd. of
Lloydmister
Saskatchewan
(Canada) needed a
flowmeter that could
accurately measure
sand slurry flow
without being
damaged by this
highly abrasive
product. They 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. This 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 flow to the wellbore.
CanFrac consulted Tarpon Energy Services of
Calgary, Alberta for solutions when their inline
flowmeters 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 flowmeter's digital display to
monitor flow rates and take daily readings from
the meter's built-in totalizer.

Greyline Doppler Flow Meters and Flow Switches
are ideal to measure flow of “difficult” liquids
including mining slurries, wastewater and aerated
liquids. For complete information visit
