AFLOWT EM470 Slurry Electromagnetic Flow Meter

Noise is common in process fluids containing solid particulates, and it can influence the measurement. Slurry magnetic flow meter AFLOWT EM470 adopts square wave excitation and 25Hz/30Hz high excitation, which can eliminate interfacerence between the sharp wave noise generated by solid particles, ensures accurate measurement of viscous medium.

Features

Special design grouting converter: Special converter can eliminate interfacerence between the sharp wave noise generated by solid particles.
Medium concentration: the concentration of slurry can reach 55%, and the variation range is usually less than 5%.
Excitation method: square wave excitation (4 kinds of square waves) impoves flow measurement stability.
Excitation Frequency: 25 Hz/30 Hz excitation frequency for choose. High excitation frequency has high anti-interference ability, ensures accurate measurement of viscous medium.
LCD backlight display: instantaneous flow, total flow, flow velocity, percentage flow, etc.

Industries

Cement slurry, sludge, gypsum slurry, paper pulp, juice, syrup, ore slurry, coal slurry, etc.
