Overview of desulfurization on-line densimeter
Intelligent online densimeter (also known as online density transmitter) is used for a continuous online measurement of liquid concentration and density of the equipment, and can be used directly in the process of industrial production. J intelligent online densimeter uses the principle of differential pressure densimeter according to differential pressure medium in a certain vertical distance value calculation
The density value, and automatic temperature compensation, high precision, good reliability, simple to install and use.
For two wire density transmitter, mainly used for industrial process control, density gauge of generating 4-20mA signal according to the size of the concentration and density, can perform remote calibration and monitoring through digital communication.

Desulfurization on-line densimeter
1, the density gauge is suitable for the static or flowing liquid, which is suitable for the pipeline and tank installation.
2, using two wire transmitter with integrated structure, no moving parts, simple maintenance.
3, continuous measurement of liquid density and temperature, can be directly used without interruption during the production process control.
4, four and a half digital liquid crystal display.
5, temperature and density of the two parameters can be displayed at the same time, to facilitate the industry standard density conversion.
6, density meter with a touch of several different liquid material.
7, convenient installation and use, can be inserted into the liquid display reading.
8, to simplify the repair, no need of regular cleaning.
9, density gauge calibration without standard reference source, without the need for laboratory calibration, without interruption.
10, the intrinsically safe type can be used for the dangerous scene. Health type can be installed in the food production site.

9, petrochemical (natural gas, oil and gas washing, kerosene, lubricants, oil / water interface)

Desulfurization on-line densimeter installation notes
Principle 1, density gauge double flange differential pressure method is established on the basis of in static pressure. Because the measured liquid sometimes is not static, it is constantly circulating and stir. So using device for hydrostatic test principle must overcome the influence of density. Not suitable for direct measurement of the local to add auxiliary test tank, let density meter working in very small flow velocity and fluctuation of the place, in order to ensure the stability of densitometer readings.
2, the specific installation diagram by engineering and technical personnel on site according to the purchased equipment size to design their own decision.
3, the flow of a liquid or liquid test when a large shock to the installation of auxiliary measuring tank, the purpose is to make the measurement readings stability. The field operators in the regulation of liquid flow rate measuring tank to take into consideration the dynamic and stability of two kinds of required readings.
4, site installation density timing must be to ensure that the two pressure repeater in the same vertical plane, otherwise it will produce difference measurement.
5, the site measured liquid must remain no two measuring sensors
6, density gauge theory can be measured according to the medium with different concentration, please use the party according to the site automatically converted from the concentration results.

Online densimeter maintenance and troubleshooting
1, the two sensor head is density meter most vulnerable position, external injury may lead to damage caused by density meter. Transport and installation in order to protect the sensor from being damaged, the protective cover must be installed on the rear to complete demolition. Remember!!
2, density meter factory has been adjusted to the best state, non professional personnel do not arbitrarily adjust. Methods in situ calibration professionals: density meter vertically into pure water, support HART protocol table operator hands adjustment. The specific operation according to the instrument instructions.
3, it is found that the density transmitter does not work when the first check the power supply and the ground is connected.
4, find the transmitter readings and the actual serious discrepancies, diaphragm check first whether two film box by the external damage deformation.

Desulfurization on-line densimeter matters needing attention
1 the solution to be tested is in the tank or in the pipeline in two? Maximum pressure of not more than 5MPa.
2 if the solution to be tested is in the pipeline, the flow velocity of the solution is not more than 0.4 meters per second.
3 pipe diameter minimum of not less than DN80.
4 the tested solution flow per hour of not more than 26 cubic meters per hour.
5 if the analyte in the tank, the customer should prepare the protective cover.
6 measuring range and accuracy?
