的使用常识金属管浮子流量计的使用场合:浮子流量计使用较为广泛,一般用于测量中、小流量和微流量,测量介质一般为清洁、不易结晶和凝固、粘度不大的液体和气体、蒸汽,要求介质流速变化缓慢。 The common use of metal tube float flowmeters: The use of metal tube float flowmeters: Float flowmeters are widely used, generally used for measuring medium, small and micro flows, and the measurement medium is generally clean, difficult to crystallize and solidify, and has low viscosity. The liquid, gas, and steam require slow changes in the flow rate of the medium.

分为就地型和远传型,其测量原理为恒压降变流通截面积流量计,其量程比为10:1,精度一般为1.6%。 Metal tube float flowmeter is divided into local type and remote transmission type. Its measurement principle is constant pressure drop variable flow cross-sectional area flowmeter. Its range ratio is 10: 1 and accuracy is generally 1.6%. Installation requirements for metal tube float flowmeters: The cone tube of metal tube float flowmeters must be installed vertically, not tilted, and should be strictly calibrated with a spirit level during installation, and should not be stressed during assembly. The vertical flow direction of the rotor flowmeter is from the bottom On the other hand, the medium flow direction of the horizontally mounted rotor flowmeter should be consistent with its marked direction. In order to facilitate the use and disassembly, the valve group is generally required to be installed. The remote transmission type of metal tube float flowmeter is magnetically coupled to the rotor. If the medium contains small particles that are easily adsorbed by magnetic substances, the rotor is easily worn and jammed, resulting in inaccurate or impossible measurement. The solution is to install a magnetic filter in front. Method for commissioning and deactivating the metal tube float flowmeter: A. Before the flowmeter is put into operation, check whether the installation meets the requirements, whether the pipeline is clean and clean, and whether the pressure test has been completed; B. Make sure that the flowmeter is It runs smoothly within its effective measuring range, preventing large flow from impacting the rotor when the meter is opened to prevent damage to the meter; C. After the flowmeter is deactivated, check whether the measuring element is contaminated and whether iron debris is adsorbed on the rotor. The rotor is cleaned.

是工业自动化过程控制中常用的一种变面积流量测量仪表。 HR-F metal tube float flowmeter is a variable area flow measurement instrument commonly used in industrial automation process control. It has the characteristics of small size, large detection range and convenient use. It can be used to measure the flow of liquid, gas and steam, especially suitable for medium flow measurement with low flow rate and small flow. HR-F series intelligent metal tube float flow meter has local display type and intelligent remote transmission type, with pointer display instantaneous / cumulative flow liquid crystal display, upper and lower limit alarm output, cumulative pulse output, batch control, standard two-wire system 4 ~ 20mA current output and other forms. Provides users with a very wide choice of space. In addition, the instrument uses an advanced micro-processing central chip and high-quality industrial components. According to the structure of the measuring tube, the HR-F series metal tube float flowmeter is divided into HR-F, HR-F1, HR-F2 and HR-F3 types. Different types of measuring tubes can be selected according to different requirements of users. There are further improvements in cleaning. On this basis, combined with the HR-FD type intelligent metal tube float flowmeter indicator, an intelligent metal tube float flowmeter can be formed. Over the years, various excellent performance and reliability of metal tube float flow meters, as well as better performance-price ratio. Widely favored by petrochemical, steel, power, metallurgy, light industry, food, pharmaceutical, and water treatment.
