Seeking help from experts: it’s a reaction tank, with clear liquid (containing process materials and water) on the upper layer, and solid resin (in the form of small particles) on the lower layer. The pressure is 0.2 MPa, and the temperature is room temperature. To measure the height of a solid (i.e., the solid-liquid interface), what instrument should be used?
Radar level gauges, radio frequency admittance level gauges, and plug-in double-flange types can be considered; in theory, all of them can be used for measurement. The estimate using a float ball doesn’t work well; it tends to get stuck. Parameters that still need to be confirmed include the interface height and dielectric constant, in order to further analyze which one is suitable.
