的使用常识金属管转子（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 use of metal tube float flow meter Common sense metal tube rotor (float) flow meter is used in: Float flow meter is widely used, generally used for measuring medium, small flow and micro flow, the measurement medium is generally clean, difficult to crystallize and solidify, Low viscosity liquids, gases, and steam require slow changes in the flow rate of the medium. 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 rotor flowmeters: The cone tube of metal tube rotor flowmeters must be installed vertically and not tilted. Strict calibration with a spirit level should be used during installation and should not be stressed during assembly. The medium flow direction of the vertical installation type rotor flowmeter is from the bottom. On the other hand, the flow direction of the horizontally mounted float flow meter should be consistent with the direction indicated. In order to facilitate the use and disassembly, the valve group is generally required to be installed. The remote transmission part of the remote-type metal tube rotor flowmeter is magnetically coupled to the rotor. If the medium contains small particles that are easily adsorbed by magnetic substances, the rotor is liable to be worn and jammed, resulting in inaccurate or impossible measurement. The solution is to install a magnetic filter in front.
的投用与停用方法： Commissioning and decommissioning method of metal tube rotor flowmeter :
A. Before the flow meter is put into use, check whether the installation meets the requirements, whether the pipeline is clean and clean, and whether the pressure test has been completed. B. After the flow meter is put into use, ensure that the flow meter runs smoothly within its effective measurement range. The flow impacts the rotor and causes damage to the instrument; C. After the flowmeter is deactivated, check whether the measuring element is contaminated and whether iron debris is adsorbed on the rotor. Clean the flow element and rotor in a timely manner. Metal tube float flowmeter is because the metal tube float flowmeter is of good quality and is slow to sell throughout the country. The metal tube float flow meter is simple in principle, but it has four advantages: better stability, convenient installation, wide application area and longer service life. Metal tube float flowmeter is also called magnetic float level gauge. Metal tube float flowmeter is affected by temperature, pressure and measuring medium. Talk about the classification of this product:
1. The device can be divided into two types: side-mounted and top-mounted. 2. From the aspect of material selection, it can be divided into 202, 304, 316 stainless steel, PVC material, lined with PTFE metal tube float flowmeter. 金属管浮子流量计 。 3. From the temperature and pressure, it can be divided into: ordinary type, low temperature type, low pressure type, low temperature and low pressure type metal tube float flowmeter . Metal tube float flowmeter can wear 4-20mA remote transmission signal, complete short-range display and grasp the liquid level. Metal tube float flowmeter is mainly used in petroleum, chemical, light industry, electric power, nuclear industry and food, medical and other industries to guide and master the liquid level of various media in containers such as tanks, tanks and tanks. Many customers often provide incomplete parameters when consulting or ordering metal tube float flowmeters. Metal tube float flowmeters are products that are customized according to customer requirements. Therefore, it is necessary to supply the correct parameters. Ordering instructions for flow meters are briefly introduced. 1. Detailed model: Detailed model can be found on our company's website 2.
