Intelligent Pipeline Online Densimeter

1. Overview

Intelligent Pipeline Online Densimeter is a kind of automatic online density measuring instrument for various liquid or liquid mixture, widely used in industries of food, beverage, pharmaceutical, petroleum, petrochemical, mining and water treatment, and etc.

The densimeter can continuously measure liquid density and directly control production process online without interruption. Integrated of the two wire transmitter structure without any moving part, the densimeter can be conveniently installed, operated, and easily maintained.

2. Working Principle?

Intelligent pipeline online densimeter is a kind of differential pressure transmitter essentially. Its working principle: The pressure of a certain height of liquid column is proportional to the liquid density. That is:

P= ρgh

P – Pressure of a certain height of liquid column ρ: Density of its liquid g: Acceleration of gravity h: Height of liquid column

According to pressure value measured, we can get the measurement of liquid density in the known condition of the acceleration of gravity and the height of liquid column.
