flow meters

Measuring the flow of slurry—whether it’s mining tailings, concrete, or drilling mud—is one of the toughest challenges in industrial instrumentation. While Electromagnetic Flowmeters (EMFs) are the go-to choice for conductive liquids, the abrasive and noisy nature of slurry can turn a standard magmeter into a maintenance nightmare. However, with the right technology and installation, you can achieve reliable, accurate readings. Here is a guide to the common problems engineers face with slurry, and how to solve them.   1. The " Slurry Noise " Problem The Issue: Slurry contains solid particles crashing against the electrodes. This creates massive electrical noise (spikes) on the output signal, making the reading unstable. The Solution: You need a meter with a high-frequency or dual-frequency excitation. Standard DC excitation is too slow; high-frequency excitation "punches through" the noise to get a clean signal.  2. Electrode Coating and Wear The Issue: Sticky slu...
