Dielectric constant as one of the main parameters used to monitor the state of working fluid

It is shown that flow density must be estimated along with measuring the temperature (or pressure) for monitoring the state of two-phase medium. To this end, it is proposed to use a dielectric constant of coolant. A simple single-parameter relation is proposed, the use of which makes it possible to calculate the density of water and steam with the known values of temperature and dielectric constant in a concrete part of heat-transfer equipment.
