Desalter脱盐界面变送器的详细资料

Desalter脱盐界面变送器

Overview

The Drexelbrook Desalter Interface Transmitter provides an excellent solution for control of vessels that use electrostatic grids to accelerate separation. The Desalter Interface Transmitter accuray measures the electrical interface of the emulsion. This measurement is critical because the separation vessel operates at maximum efficiency when the electrostatic grid is close as possible to the interface.Desalter脱盐界面变送器
