Selection of interface meter
Thread Content
My company has several locations where it is necessary to measure interfaces; the densities of the two-phase liquids are around 0.925 and 0.99 respectively. Which type of interface detector would be more effective in these cases? Please share your experiences more; thank you
OP, many factors need to be considered in the measurement interface: 1. First of all, what is the thickness of the mixing layer between the two media? 2. Is the density of the medium being measured constant? 3. Is there a large difference in the electrical conductivity of the media? 4. What type of container and how are the instruments installed? If the medium density is stable, the conductivity is low, and it is installed on the side, a double-flange differential pressure transmitter can be used; if it is installed at the top, a float level gauge should be used ； If the dielectric density is unstable and the conductivity coefficients vary significantly, an RF admittance interface meter can be used; if the container is non-conductive, a dual-rod RF admittance interface meter should be employed.
You need to specify the density, temperature, corrosivity, etc. of the material
