Molasses large tank level measurement
Thread Content
Dear friends: We are considering building several large tanks for molasses, in order to store the sugarcane molasses supplied by the sugarcane refineries. The cylinder height of the large molasses tank is 10 meters, with a head on top. We plan to install a set of level measurement instruments on the large molasses tank; we’re not sure which type would be more suitable. In the old factories, our large molasses tanks used float-ball weight-type indicating scales that were welded from steel plates on site. Introduction to other conditions: The molasses used is sugarcane molasses, which is a by-product of sugar production from sugarcane; it is quite viscous, with a Bx value of around 80 ； The construction site does not freeze in winter either, with the lowest temperatures remaining above 15 degrees, so freezing is not a concern. Preliminary consideration: single-flange inserted diaphragm-type differential pressure transmitter ； Alternatively, a radar level gauge can be installed on the tank top head. I would appreciate some advice; experience in actual use would be even better!
For safety, install both to have a comparison.
Put both in. A radar level gauge would be better, right? Single-flange level gauge: As the density of the medium changes due to temperature variations, the level indicated during the day and at night will differ slightly
It is recommended that you use a radar level gauge, as it is not affected by the density of the material inside the storage tank. Radar level gauges, on the other hand, are greatly influenced by the density of the liquid being measured, which can result in significant errors
It is recommended to install and use both single-flange level gauges and top radar level gauges. More reliable.
If you want to reduce maintenance efforts, it is recommended to use radar
Tip: For sugar tanks, differential pressure should be used, taking into account the issue of sugar crystallization in the medium. It is necessary to confirm with the process whether this will occur. .
Hehe, I’m ashamed. I’m the one in charge of the craftsmanship. Our old molasses tanks used float-weight type level gauges made of steel plates. I have never used either differential or radar-type remote transmission level gauges.
Personal opinions for reference only: 1. If the budget permits, it’s a good idea to install two units, as this allows for comparison over time. 2. To reduce maintenance needs in the future, it is recommended to use contactless radar level gauges; they are not affected by factors such as temperature, density, or steam, have strong resistance to interference, and provide stable and reliable measurement results! High precision, small blind spot. Those who are interested in radar in the future are welcome to add me on WeChat for ongoing communication! V: 15656527378
