The finished product tank is filled with materials into the tank. The material is organic matter with a specific gravity of about 1. It is transported by a pump. The flow rate of the pump is 25m3/h and the lift is 20m. The cargo owner requires a tank filling capacity of 20 tons, plus or minus not exceeding 100 kilograms, to meet the requirements of shipping. Of course, the final settlement price of the goods is based on the weight of the floor scale. The finished product There are 6 steel plastic-lined storage tanks with a volume of 70m3. Since it is difficult to calibrate the storage tanks at different liquid levels, and the differences in the tanks and the thickness of the plastic lining are not very uniform due to the manufacturing reasons of the storage tanks, the calculated storage tank volumes at different liquid levels can only be used as a reference, and there is still a certain difference with the actual situation. Therefore, in view of the strict requirements of the cargo owner, we envisage using a flow meter to feed materials to the tank more accurately. The question is which form of flow meter should we choose, which is more suitable for our usage requirements? Please give me some help and advice, thank you!
It is recommended to use a mass flow meter. When it comes to finished products leaving the factory, accurate measurement is required, and there is also a comparison of weighing data.
It is recommended to adopt a quantitative loading system. In the situation mentioned by the poster, I think the quantitative loading system can fully meet the needs. I am not a manufacturer, and I have done several projects that include loading systems. The current development trend is to use quantitative loading systems. The system is not complicated. For the specific settings, you can search online or find a manufacturer and ask the manufacturer to cooperate! Answered!
Our factory uses relatively high-precision mass flow meters, and the general error is within 100 kilograms.
It is recommended to use a mass flow meter to achieve quantitative canning
You can use the mass flow meter produced by Emerson, which has high accuracy, and then set the relevant logic to implement a quantitative loading system. After leaving the factory, go through the weighing scale and compare the two sets of data.
It is best to choose a mass flow meter because it can be more accurate.
For liquids, mass flow meters and volume flow meters are similar.
Quantitative loading systems can generally meet this requirement. If it is only for temporary use, it is not necessary. My suggestion is to install a temporary mass flow meter. The corresponding filter must be installed in front. Install it according to the quantity at the bottom of the table. There will be no problem. After installation, go to the weighbridge and never exceed it. Let me add something. Generally, floor scales start at 20 kilograms, so you should pay attention when installing. If you install 10 tons of oil, you need to reduce 20 kilograms on the basis of 10 tons. According to this standard, it is generally very standard.

There will be a certain error, but as long as there are no external factors affecting the flow meter, the error value is certain. As long as this error is taken into account when loading the vehicle, it will be more accurate.
Has LZ considered the nature of the product or the simultaneous operation of other processes?
