Tailings, thickener underflow, dewatering, process slurry
Tailings and thickener underflow are abrasive, dense, and variable. A wetted flow meter in that service is not an instrument, it is a consumable — and one with a replacement schedule and an outage attached to it.
Clamp-on transducers sit on the outside of the pipe. They are not in the abrasion path at all. Nothing wears. Nothing erodes. There is nothing in the flow to replace.
Slurry is exactly the fluid a transit-time meter cannot see — the pulse scatters off the solids and the meter drops out. It is also exactly the fluid Doppler requires, because Doppler works by reflecting off those solids.
The Compu-Flow C6 Fixed Doppler is the instrument: 0.5″ to 500″ pipe ID, unaffected by changes in viscosity, density or speed of sound — which matters enormously on a line whose solids loading swings hour to hour.
Dewatering points and monitoring locations on a mine site are frequently a long way from anything. The C6 runs on AC, DC, solar, or battery, and supports cable runs to 5000 feet between transducer and display.
That cable spec is doing more work than it looks. The pipe you need to meter is at the bottom of a pit. The place a person can safely stand and read a display is not. Five thousand feet of separation means you put each one where it belongs.
A Doppler meter needs reflectors. If your line runs clean during a wash-through cycle, or dilutes heavily in the wet season, the meter will go dark exactly then — which is exactly when something unusual is happening and you wanted the data.
Tell us if the fluid changes. It is the question people skip and the one they regret.
Send us the pipe and the fluid. An application engineer will confirm the right instrument — or tell you clamp-on is the wrong answer, which happens and which we would rather say first.
