Introduction to FWC&D-A1 Capacitive Concentration Meter and Density Meter Products

Product Introduction

A fluid concentration online measurement device specifically developed for solid-liquid two-phase fluids with high concentration and wide range of concentration changes. Compared to the commonly used radiation concentration meter in iron mines, this concentration meter has outstanding advantages: firstly, it avoids the difficulties in safety and management caused by the use of radioactive sources, as well as the potential harm to the health of employees; At the same time, it solves the problem that the radiation concentration meter cannot accurately measure concentrations that vary over a large range.

measuring principle

Adopting relative capacitance method and self sampling measurement method. Select two measuring tube segments with the same cross-section and length, install a pair of electrodes on the measuring tube, apply a stable high-frequency sine signal to the electrodes, and measure the capacitance of solid and liquid two-phase fluids and the capacitance of pure liquid objects separated from solid and liquid two-phase fluids, respectively. The capacitance size is related to the density and concentration of the measured medium.

Technical features of the product

(1) Multi purpose, synchronous measurement: volume concentration, mass concentration, and density of solid and liquid two-phase flow;

(2) Realize high-precision, online continuous measurement for solid and liquid two-phase flow with large range of concentration and density changes;

(3) On site calibration does not require downtime, with a single sampling calibration process that is concise and efficient;

(4) No movable parts, stable and reliable long-term operation;

(5) No radioactive source, safe operation, no need for daily maintenance.
