I. Insertion type online density meter working principle

On-line density meter (also called differential pressure on-line density meter) can be used to measure the density of various liquids or liquid mixtures on-line. In the petrochemical industry can be widely used in petroleum, oil refining, oil mixing, oil and water interface testing; in the food industry for grape juice, tomato juice, fruit syrup, vegetable oil and soft drinks processing and other production sites; dairy industry; paper industry; alkali solution testing; brewing alcohol; chemical industry, urea, desulfurization, ammonia, sulfuric acid, and polymer density testing. It can also be applied to mining slurry, brine, potassium alkali, natural gas, lubricating oil, biopharmaceutical and other industries.

Second, the main features of the insertion type online density meter

1, the use of integrated structure of the two-wire transmitter, no moving parts and simple maintenance.

2、Four and a half digits liquid crystal display.

3、Easy to install and use, inserted into the liquid can display readings.

4、Used in fluid or static liquid, suitable for pipeline and tank installation.

5, temperature and density of the two parameters can be alternately displayed, easy to industry standard density conversion.

6, continuous online measurement of liquid density without process interruption, can be directly used for production process control.

7, contact with the liquid parts of all for several media stainless steel material manufacturing, safety; health.

Third, the insertion of online density meter technical indicators

1、4~20mA current output. Optional digital signal (HART protocol)

2, 16 ~ 30VDC power supply. Recommended use of 24VDC.

3, density range: 0 ~ 2 g / cm3; 0 ~ 3 g / cm3

4, precision: 0.001 g / cubic centimeter

5, Resolution: 0.0005 g / cubic centimeter

6、Temperature range：0～100℃

7, temperature accuracy: 0.2 ℃

8、Ambient Temperature：-10～60℃

9, humidity range: 0 ~ 90%

Insertion type on-line density meter installation guide

1, online density meter sensor part of the minimum distance of 200mm, diameter of 50mm, the field can not be smaller than these dimensions installation, such as the choice of bending type density meter, please measure the flange can be extended into the pipe and the length of the size.

2, the site liquid must be kept below the two measurement sensors, flange to **** the distance from the sensor can be selected.

3, pipeline installation needs to let the liquid from the bottom of the sensor into the liquid, or from the top of the sensor into the liquid, not from the center into the liquid. Pipeline installation through the liquid, the pipeline valve or elbow part of at least 30CM liquid buffer distance.

4, equipped with a power supply for 24VDC output 4-20mA signal such as the need to connect the secondary meter, need to connect 24V “+”

5, the site environment if the external corrosive liquid, please take protective measures. If there is a risk of lightning strike, please do a good job around the grounding device.

6, such as the need to disassemble to do cleaning, disassembly, please ensure that the sensor diaphragm is not subject to collision and other damage.

7、Do not use it in the case of higher than 5Mpa.

8, if you need to adjust the range need to use a handheld device, technical problems, please contact the manufacturer.

6、

Insertion type online density meter ordering instructions

1, the density meter diaphragm for the weakest part please do not let the sharp objects impact to the diaphragm caused by the destruction.

2、Online density meter can theoretically be measured according to the concentration of different media, please use the method according to the site conditions to convert the concentration of their own results.

3、Please contact the manufacturer when selecting the type, and provide the site installation, and indicate when signing the contract.

4、If you need calibration, or adjustment, please contact the manufacturer.
