Intelligent online density meter

1.Overview

Automatic measuring instrument for on-line measurement of the density of a variety of liquid or liquid mixtures by a smart online density meter. Widely used in the oil, oil refining, oil and water interface detection in the food industry, it is used in the detection of grape juice, tomato juice, fruit syrup, vegetable oil and soft drinks. In the chemical industry, it is also used in the detection of cleaning agent, ethylene glycol, urea and polymer density. It is also widely used in pharmaceutical industry, dairy industry, mining industry, etc.

The smart online density meter can be continuous on-line measurement of liquid density, no process interruption, can be directly used in the production process control. The integration of the two wire transmitter structure, no moving parts, simple maintenance and convenient installation and use. 

2.Working principle

Intelligent online density meter is essentially a differential pressure transmitter. Its working principle: the pressure of a certain height of liquid column is proportional to the density of the liquid.

P=ρgh: P -- Pressure of a certain height of liquid column 

ρ - The liquid density

g - Measurement of earth gravity acceleration

h - Height of liquid column

According to the pressure measured by the pressure gauge, the density value of the measured liquid can be obtained under the condition that the gravity acceleration and the height of the liquid column as the known conditions.

Intrinsically safe type can be used for dangerous environment

Health type can be used in food, pharmaceutical production site

5.Using method

5.1  Installation method

There are two types of smart online density meter in the structure, which is the top mounting type and the side mounting type. The top mounting type is suitable for the installation of the tank, and the side mounting type is suitable for the pipe installation, in order to meet the requirement of the density measurement under different working conditions.

5.3 Read density values 

Intelligent online density meter factory, the display meter reading is for the measurement of real density value, can be directly read.

With (4~20) mA current output of the density meter, the 4mA corresponding to the density meter density measurement of the lower limit, while the 20mA is corresponding to the density meter density measurement of the upper limit value. According to the current value of the actual measurement, the current value corresponding to the upper and lower limit of the density meter is converted to the corresponding density value. The current value obtained by the actual measurement should be converted according to the current value corresponding to the upper and lower limit of the density meter. For example, the lower 4mA output corresponding to the density value of 0g/cm3, the upper bound 20mA output corresponding to the density of 2g/cm3, the corresponding density value, then: (2-0) x (12-4) / (20-4) =1 (g/cm3)

7. Note

 

7.1 Smart online density meter for automatic precision measuring instrument, its measuring diaphragm in addition to being measured pressure shall not bear any other external force.

 

7.2 In the installation of smart online density time, should ensure that the vertical installation (vertical to the ground plane, that is, the measurement of the degree of confidentiality of the column is perpendicular to the horizontal plane), otherwise it will produce the measurement error.

 

7.3 When ordering, should be clearly stated in the measurement medium, measurement range, the use of gravity acceleration (or indicate the use of the region name) and the use of field conditions (such as: explosion-proof, anti-corrosion, health, etc.).
