Product Q&A

Q:What is a battery-powered electromagnetic flow meter for gold mining?

It is a flow meter that uses electromagnetic induction to measure gold ore slurry, mining pulp, and conductive liquids. It runs on internal lithium batteries with 3-10 years of battery life .

Q:Why use a mag meter for gold ore slurry?

Mag meters have no moving parts, so they do not wear out from abrasive gold particles. With proper material selection, meter lifetime can be extended from 6 months to 3 years .

Q:What is the battery life?

Standard lithium battery provides 3-10 years of continuous operation. Extended battery options are available .

Q:Can it handle highly abrasive gold ore slurry?

Yes! The meter is available with polyurethane lining and carbide-coated Hastelloy C electrodes, specifically designed for abrasive applications like hydrocyclone feedlines .

Q:How much can this meter save in maintenance costs?

By extending meter lifetime from 6 months to 3 years, the meter can save approximately $1.5M per line every three years in production loss and replacement costs .
