First, we need to know what is slaked lime. Slaked lime, also called slaked lime or calcium hydroxide, is an inorganic compound with the chemical formula Ca(OH)2, Mr74.10. It is a white hexagonal powder crystal with a density of 2.243 g/cm3. Density 2.243g/cm3. 580° water loss into CaO. Calcium hydroxide is added to water and divided into two layers, the upper aqueous solution is called clarified lime water, and the lower suspension is called lime milk or lime slurry.
The upper clear lime water can be measured for carbon dioxide, and the liquid lime milk with lower turbidity is a building material. Calcium hydroxide is a strong alkali with bactericidal and antiseptic properties, corrosive to skin and fabrics. Calcium hydroxide is used in the manufacture of bleaching powder, hard water softeners, disinfectants and insecticides, tannery dehairing agents, sugar production, and construction materials.
A company in Shanghai installed and used our radar level meter, model RD-FMF21, the site conditions are room temperature, and negative pressure, the medium is slaked lime, the site response radar level meter has no signal, measurement is not stable. Our after-sales engineer went to the site to check and found that the receiver under the radar level meter was long and easy to accumulate dust, which led to the above problem. The after-sales engineer immediately gave a solution, the original radar level meter can no longer be used, replaced with a new radar level meter, and told the customer that regular cleaning is needed to completely avoid the above problem again.
In addition, the radar level meter used in this case is our 120G FM radar level meter, which features millimeter wave radar, measuring accuracy up to ±2mm, measuring the minimum blind area of 0.05m. The antenna size is small to meet more working condition measurements. Multiple lens antennas, small emission angle, concentrated energy, strong echo signal, and very high reliability compared with other radar products under the same working conditions.
With strong penetration, it can be used normally in the case of adhesion and condensation. Large dynamic signal range, more stable for low dielectric constant medium measurement, multiple measurement modes, fast measurement mode radar response time is less than 1S.
Combined with this article, we will find that in the more dusty working conditions, regular cleaning is necessary, if more serious, you also need to add a blowing device.
When selecting the model, you need to make your working condition clear with the manufacturer of the radar level meter, so that you can avoid a lot of unnecessary trouble, but also help us to choose the most suitable for their own working conditions of the product.
