Online liquid density/concentration tester

Online concentration meter/Density meter FBS-1000



The FBS-1000 series online densitometer can measure the density of various liquids or liquid mixtures online.

It can be widely used in the petrochemical industry for petroleum, refining, oil blending, and oil-water interface detection; Used in the food industry

On production sites for grape juice, tomato juice, fruit syrup, vegetable oil, and soft drink processing; Dairy industry; papermaking

Business; Testing of black, green, white, and alkaline solutions; Alcohol content in brewing; Urea, cleaning agents, and ethylene in the chemical industry

Testing of diols, acidity and alkalinity, and polymer density. It can also be applied to mining salt water, potassium alkali, natural gas, lubricating oil

Industries such as biopharmaceuticals.



1. The two-wire transmitter adopts an integrated structure, with no moving parts and simple maintenance

2. Four and a half digit LCD display

3. Easy to install and use, simply insert the liquid to display the reading

4. Used for fluids or stationary liquids, suitable for pipeline and tank installation

5. The two parameters of temperature and density can be displayed alternately, making it convenient for industry standard density conversion

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

7. All parts in contact with liquids are made of several types of medium stainless steel materials, ensuring safety; hygiene.

8. This safety type can be used in hazardous environments; Sanitary type can be installed on food production sites

Ordering precautions

1. When placing an order, specify the medium, measuring range, and on-site operating conditions, such as explosion-proof, corrosive, hygienic, and ordinary

Selection instructions:

1: The minimum distance between the sensors of the direct online liquid density meter is 200mm, and the diameter is 50mm. The installation size on site cannot be smaller than these dimensions. If a curved density meter is selected, please measure the flange and length dimensions that can be inserted into the pipe

2: The on-site liquid must be kept at least two measuring sensors, and the distance from the flange to the first sensor is optional

3: During pipeline installation, it is necessary to allow liquid to enter from below the sensor at the bottom or from above the sensor at the top, and not from the middle. When installing pipelines for liquid flow, at least 30CM of liquid buffer distance should be left at the valve or elbow part of the pipeline.

4: The red flange matching part of the installation diagram is provided for installation by the user. If matching flanges are needed, please specify when placing an order

5: Equipped with a power supply of 24V DC output 4-20mA signal. If a secondary meter is required, the 24V "+" should be connected
Connect the "+" pole behind the density meter, connect the "+" current signal to the "-" pole of the density meter, and short-circuit the 24V "-" and current signal terminals "-" on the secondary meter

6: If there are corrosive liquids outside the site environment, please take protective measures. If there is a risk of lightning strikes, please install grounding devices in the surrounding area.

7: When disassembling for cleaning, please ensure that the sensor diaphragm is not damaged by collision or other factors.

8: Do not use it above 5Mpa.
