Glass rotor flowmeters should be said to be widely used in the field of industrial use, and it is also the largest number of types used, such as chemical industry, petroleum industry, pharmaceutical industry, light industry, food industry, environmental protection industry, etc. Used to measure the flow of a single-phase non-pulsating fluid, where the fluid is gas and liquid. The role and characteristics of the glass rotameter is very obvious. The instantaneous flow of the fluid is measured. The pressure loss during the measurement is small and the performance is reliable. The glass rotameter has a simple structure and is easy to install and use. The glass is relatively to the flowmeter. Rotameters are very inexpensive. 1. How to correctly use anti-corrosion glass rotor flowmeter: Â The glass rotor flowmeter can be divided into: ordinary type, ribbed tube type, small flow rate and small size type, corrosion resistant type, laboratory type, heat preservation type, alarm type, and high pressure resistant type according to its use and adaptation range. series. According to the national series of instrument series, no matter which series, the maximum number includes 12 calibers from 1 mm to 100 mm. The measurable flow ranges are: liquid (water) 0.1 ml/min to 40 cubic meters/hr, gas (Air) 1 ml/min to 1000 cubic meters/hour. The glass rotor flowmeter used for environmental protection instruments is generally not more than 10mm in diameter, and the measured flow is in a small flow range. 3, scale correction of glass rotor flowmeter: Hot melt adhesive for carton sealing
Shipping cartons must be able to withstand temperature, humidity changes, and rough handling, which is more difficult to meet with tape because of its poor bond strength, low tensile strength, and poor adhesion to coated or oil-based cardboard.

For such a significant effect, the widely accepted flow meter does not only need to know its function, but also how to play its biggest role. How to select the most suitable glass rotor flow meter according to the measuring medium? , so that the use of the effect of measuring better.
First of all, in the selection of a glass rotameter must have a range of approximate measurement values, the maximum flow rate of the medium to be measured, not to say that the larger the flow rate range that can be measured by the glass rotameter, the better, but also consider the pressure of the fluid The scope, after all, is a glass tube product that can withstand a certain limit of pressure. Flow range, pressure range is a matter of choice that must be considered.
Of course, there is also a problem of measuring the medium. The density of any medium is different, and the characteristics of any kind of medium are also different. Changzhou Chengfeng Meter, the flowmeter, calibrates the scale of the glass tube on the glass rotameter according to the specific measuring medium to ensure the accuracy of the measurement. The measuring medium also needs to be provided to the flow meter manufacturer when it is selected. There are many substances that are corrosive, such as strong acids, alkalis, oxidants, organic solvents, etc. Corrosive fluids need to use the corresponding technology to achieve the effect of anti-corrosion, to ensure the normal measurement instrument use.
Glass Rotameter is a kind of instantaneous flow measuring instrument which is easy to use, easy to read and widely used. In the category of environmental protection equipment, we want to use it widely. Therefore, it is extremely important to choose and use this instrument glass rotor flowmeter.
2. The variety and selection of glass in the flowmeter
The scale of the glass rotameter is obtained by the manufacturer using the near-ideal fluid water and dry air as the medium under the conditions of the factory. However, in the use of the flowmeter, there are two situations in which its scale value cannot be used directly: one is that the measurement medium is not water and air, and the second is measurement and the medium is water and air, but its state (temperature, pressure) and scale Different states. In this way, when using the flowmeter, in order to obtain correct measurement results, there arises the problem that the scale value needs to be corrected. Therefore, to solve the glass rotor flowmeter calibration correction is the key to using this instrument.
4. Summary:
Considering that environmental protection instruments use glass rotameters and corrosion-resistant glass rotameters measure a large amount of gas medium flow, the following discussion only deals with density corrections when measuring gaseous media. Since the viscosity of the gaseous medium is small, the effect of viscosity is omitted in the discussion. Practice has shown that this does not affect the accuracy of the correction.
Select the appropriate flow meter, according to the actual needs of the situation to select the most appropriate flow meter to ensure the best efficiency, the most reliable performance. Changzhou Liangbang meter flowmeter manufacturers, as a well-known domestic flowmeter manufacturers, in the guarantee of product quality, while ensuring the quality of the flowmeter, to give customers the most appropriate flow meter application design choices.
Hot-melt adhesive sealing is to use a hot-melt machine to melt the hot-melt adhesive into a liquid, and then send it to the surface of the carton through the throat and spray gun of the hot-melt machine. After the hot-melt adhesive is cooled, the bonding is completed. It can meet various requirements of carton sealing, and overcome the defects existing in the traditional carton sealing form.
