Density transmitter is a device that continuously measures density online. It can be directly used in industrial production processes. According to Archimedes principle, it adopts electronic technology, which consists of a capacitive differential pressure sensor and its connection, a pair of pressure sensitive diaphragms with a temperature sensor between them. It can offset the temperature change of the process liquid.

The density transmitter can electronically offset the nonlinear state change of SF6 gas according to Virial equation. It can collect the pressure and temperature of SF6 gas in the equipment (tank), and then use these two variables to determine the current gas density through an electronic evaluation system. The system will dynamically offset the thermally induced pressure change to avoid the influence on the output signal.
