I work in a pharmaceutical factory, and we have a new production line that requires real-time measurement of the density of the liquid inside tanks. I would like to know what are the available brands of online density meters, both in China and abroad (Emerson, Yokogawa? ? ) What are the options available in China, and what’s their quality? (Without considering the use of a mass flow meter.) (Additionally: for confidentiality reasons, it’s not possible to specify more detailed parameters; I’d like to know the brand first.) (If there are samples available, it would be greatly appreciated if you could send them to auto_my@163.com.)

Among online density meters, the most classic and practical one is the U-tube density meter; represented by Yokogawa’s DM8 series, it can be used for conventional oils, water solutions that do not cause significant corrosion, as well as certain suspensions and emulsions. There are also specialized models designed for use with caustic soda, namely vibrating U-tubes made of nickel, which are widely used in the determination of caustic soda density. Since the sampling and sample processing systems used alongside them are also made of materials resistant to strong alkalis, they are extensively utilized in the ion-exchange membrane caustic soda industry. Another type is the ultrasonic densitometer, which uses a probe installed inside a pipeline or container; its apparent accuracy is close to that of the U-tube densitometer, but its actual precision is slightly lower. Another type is the densitometer that converts based on a fixed liquid level pressure difference, that is, it uses a differential pressure transmitter to output the differential pressure value at a fixed liquid level. The data reliability of this measurement method is highly dependent on the location chosen for measurement as well as the reliability of the transmitter. When looking for an analyzer, it is necessary to provide the manufacturer with the relevant physical and chemical parameters; these parameters are merely data, not the confidential names or production processes of the products manufactured by your pharmaceutical factory. Are temperature, pressure, density ranges and similar values also considered confidential?

If it’s the density of the liquid inside a tank, a simple and effective solution is to use a double-flange differential pressure density meter; it functions like a double-flange level gauge, with the condition that both upper and lower flanges must be below the liquid surface. Any manufacturer that can produce double-flange differential pressure transmitters can do it. Additionally, for higher-end options, Emerson offers a fork-type density meter that is used for measuring density inside tanks. Well, leaving aside its accuracy and stability, the only word that describes it is expensive. Expensive means high-quality; expensive means justice.

Big brands, bro. When it comes to big brands, they’re just the ones who do the rough and dirty work. . . It is only small brands that produce high-quality, premium products at affordable prices. Shuaike – Shuaike Sensing Instrument Manufacturing Company, which is also my company where I work. Have you heard of it? Hey guys who have heard of this meter, come and post your comments at #1111111! :P Portable dual-use 2-second flash density analyzer (intrinsically safe, explosion-proof) Portable immersion slurry density analyzer (intrinsically safe, explosion-proof)

I’m currently using a double-flange differential pressure density meter to measure the density of ammonia solution online, and it’s a bit tricky to verify the data obtained

Generally speaking, mass flow meters are the best for measuring density, but it’s uncertain whether your medium contains particles, which might make it difficult to use a mass flow meter You might also want to look into nuclear density meters; they can also provide accurate density measurements online.
