A mine needed flow measurement on a tailings line — dense, abrasive slurry whose solids loading swung hour to hour. Any wetted meter in that service is a consumable, and the line ran to a remote point with no mains power.
Clamp-on Doppler with the Compu-Flow C6. The transducers sit on the outside of the pipe, entirely out of the abrasion path — nothing wears because nothing touches the slurry. Doppler is also unaffected by the swinging density, viscosity, and speed of sound that come with variable solids loading, because it measures the frequency shift off the particles rather than timing a pulse through the fluid.
Remote power and cable length. The C6 runs on AC, DC, solar, or battery, and supports transducer-to-display cable runs to 5000 ft — so the transducer sits on the pipe at the pit while the display sits somewhere a person can safely read it.
On abrasive slurry, “nothing in the flow to wear” is the whole argument. Doppler's insensitivity to changing density is a bonus that happens to match exactly how tailings behave.
Send us the pipe and the fluid and we will tell you what will actually work.
