Accurately detecting coal slime water concentration during washing is crucial for optimizing dosing systems and improving separation efficiency. Traditional detection methods are often affected by flow field disturbances. To address these limitations, this paper proposes a pressure differential system utilizing interference rectification stabilized improved measurement accuracy. The experimental comprises circulating slurry tank, defoamer, turbulence removal measuring tank. Numerical simulations studies investigated the effects of inflow velocity on Through dynamic difference data under different concentrations rates, characteristics solid–liquid two-phase simulated using Fluent software. results demonstrate that low-concentration (C = 10%) high-concentration 30%) slurries, ≥0.7 m/s significantly improves uniformity achieves stable particle suspension state, maintaining error within 1% rate 0.7 m/s. However, rates exceeding decrease stability, increasing errors. Notably, combination sensors at positions No. 2 4 yields lowest errors, which verifies influence sensor layout A identified as key threshold nonlinear synergistic effect stability revealed. These findings provide valuable insights pulp enhancing industrial precision.
