Select the appropriate glass rotor flow meter according to the medium to be measured

Abstract: According to the medium to be measured, the information on selecting the appropriate glass rotor flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. It should be said that the glass rotor flowmeter is widely used in the industry, and it is also the most widely used type, such as the chemical industry, petroleum industry, pharmaceutical industry, light industry, food industry, environmental protection industry, etc. for measuring sheets. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the article on selecting the appropriate glass rotor flowmeter according to the medium to be measured. It should be said that the glass rotor flowmeter is widely used in the industry, and it is also the most widely used type, such as the chemical industry, petroleum industry, pharmaceutical industry, light industry, food industry, environmental protection industry, etc. Used to measure the flow of single-phase non-pulsating fluids, where the fluids refer to gases and liquids. The role and characteristics of the glass rotor flowmeter are very obvious. When measuring the instantaneous flow of the current fluid, the pressure loss during the measurement process is small and the performance is reliable. Moreover, the glass rotor flowmeter has a simple structure and is very convenient to install and use. The price of the rotameter is very low. For such a significant and widely accepted flowmeter, people not only need to know its function, but also need to know how to play its maximum role and how to choose the most suitable glass rotor flowmeter according to the measuring medium. , so that the effect measurement used is better. First of all, when choosing a glass rotameter, there must be an approximate measurement value range, and the maximum flow rate of the medium to be measured does not mean that the larger the flow range that can be measured by the glass rotameter, the better, but also consider the fluid pressure. The range, after all, is a glass tube product, and there is a certain limit to the pressure it can withstand. The flow range and pressure range are issues that must be considered when choosing. Of course, there is also the question of measuring the medium. The density of any kind of medium is different, and the characteristics of any kind of medium are also different. The flowmeter meter calibrates the scale of the glass tube on the glass rotor flowmeter according to the specific measurement medium to ensure the measurement accuracy. The specific measurement medium is in It also needs to be provided to the flowmeter manufacturer when selecting the model. There are also many substances that are corrosive, such as strong acids, strong bases, oxidants, organic solvents, etc. For these corrosive fluids, it is necessary to use corresponding technologies to achieve the effect of anti-corrosion and ensure the normal operation of the measuring instrument. use. 1. How to correctly choose the anti-corrosion glass rotor flowmeter: The glass rotor flowmeter is a kind of instantaneous flow measuring instrument that is easy to use, easy to read and has a wide range of uses. In the category of environmental protection equipment and instruments, the dosage should be widely used. Therefore, it is extremely important to choose and use this kind of instrument glass rotor flowmeter. 2. Types of glass rotor flowmeters and selection of glass rotor flowmeters can be divided into: ordinary type, vascular type with ribs, micro flow and small shape type, corrosion-resistant type, laboratory type, Eight series of insulation type, alarm type and high pressure type. According to the instrument series type spectrum formulated by the country, no matter which series, it includes at most 12 calibers from 1 mm to 100 mm, and the measurable flow range is: liquid (water) 0.1 ml/min ~ 40 cubic meters (Air) 1ml/min～1000m³/h. The glass rotor flowmeter used for environmental protection instruments generally has a diameter of no more than 10 mm, and the measured flow rate is in the small flow range. 3. Calibration of glass rotameter: The calibration of glass rotameter is obtained by the manufacturer using water and dry air that are close to ideal fluids as medium under the conditions of the factory. However, in the use site of the flowmeter, there are two situations where the scale value cannot be used directly: one is that the measuring medium is not water and air, and the other is that although the measuring medium is water and air, its state (temperature, pressure) and scale Status is different. In this way, when using the flowmeter, in order to obtain correct measurement results, there is a problem that the scale value needs to be corrected. Therefore, solving the calibration correction of the glass rotameter is the key to making good use of this instrument. 4. Summary: Considering the use of glass rotameters for environmental protection instruments, and a large number of anti-corrosion glass rotameters for measuring gas medium flow, the following only discusses the density correction during gas medium measurement. Since the viscosity of the gas medium is very small, the influence of viscosity is omitted from the discussion. Practice has proved that this does not affect the corrected accuracy. Select the appropriate flowmeter and choose the most suitable flowmeter according to the actual situation of the demand to ensure the best efficiency and the most reliable performance. The flowmeter manufacturer, as a well-known domestic flowmeter manufacturer, guarantees the quality of the product and the quality of the flowmeter at the same time.Give customers the most correct design choices for flowmeter applications. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
