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.
