Which is a good differential pressure densitometer

1DY-3051MD online density meterOverview
Intelligent online densitometer is an automated measuring instrument used for online density measurement of various liquids or liquid mixtures. Widely used in the petroleum industry for detecting oil, refining, blending, and oil-water interfaces; Used for density testing of grape juice, tomato juice, fruit syrup, vegetable oil, and soft drinks in food industry production sites; Used in the paper industry for detecting the density of black pulp, green pulp, white pulp, and alkaline solutions; In the chemical industry, it is also used for detecting the density of cleaning agents, ethylene glycol, carbonic acid, urea, and polymers; It is also widely used in the pharmaceutical industry, dairy industry, mining industry, and so on.
The intelligent online density meter continuously measures liquid density online without process interruption during operation. Can be directly used for controlling the production process. Adopting an integrated two-wire transmitter structure, it is easy to install and maintain without moving parts.

2DY-3051MD online density meterworking principle

The intelligent online density meter is essentially a differential pressure transmitter. Its working principle: The pressure generated by a liquid column at a certain height is proportional to the density of the liquid.
Namely: P=ρ gh, where P represents the pressure generated by a liquid column at a certain height
ρ - density of the liquid
G - Measurement of ground gravity acceleration
H - height of liquid column
Based on the pressure value measured by the pressure gauge, the density value of the measured liquid can be obtained under the condition that the ground acceleration and the height of the liquid column are known.

5.1DY-3051MD online density meterInstallation method

There are two types of structural designs for intelligent online density meters, namely top mounted and side mounted. The top installation type is suitable for tank installation, and the side installation type is suitable for pipeline installation to meet the density measurement requirements under different working conditions.

5.2 Reading Density Values
When the intelligent online density meter leaves the factory, the reading on its display head is the real-time density measurement value, which can be directly read.
A density meter with a current output of (4) mA, where 4mA corresponds to the lower limit of density measurement and 20mA corresponds to the upper limit of density measurement. According to the actual measurement of electricity
The current value is then converted according to the current values corresponding to the upper and lower limits of the density meter to obtain its corresponding density value. The actual measured current value should be converted according to the current values corresponding to the upper and lower limits of the density meter. For example, the lower limit 4mA output corresponds to a density value of 0g/cm3, and the upper limit 20mA output corresponds to a density value of 2g/cm3. When calculating the 12mA output, the corresponding density value is: (2-0) (20-4)=1 (g/cm3)
