RF Admittance is a measurement technology used for determining level of liquids, granulars, slurries & interface in almost any containment and process environment.
This technology must not be confused with RF Capacitance, but they are not the same. To draw an analogy, this would be similar to comparing a calculator with a PC, both the calculator and the PC will perform simple tasks but only the PC will provide an efficient solution to a complex problem.
Similarly, only R.F. Admittance will calculate the real level measurement in the presence of undefined and uncontrolled variables. Despite coating build ups, changes in density or electrical properties, the R.F. Admittance level measurement will not be affected, even if all are acting at the same time.
