Metal tube float flow meter has in-situ remote transmission constant pressure drop variable flow cross-sectional area
2012-3-19 15:37:16


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 and cannot be tilted. The level should be strictly calibrated during installation, and should not be stressed during assembly. 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 type metal tube float flowmeter is remotely coupled to the rotor by magnetism. If the medium contains small particles that are easily adsorbed by magnetic substances, the float is easily worn and jammed, resulting in inaccurate or impossible measurement. The solution is to install a magnetic filter in front.

是因金属管浮子流量计质量好,滞销全国各地。 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. 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. 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.

的时分,经常会供给参数不全的状况,金属管浮子流量计都是依据客户请求订制的产品,因而必需要供给正确的参数,本文就金属管浮子流量计的订货须知简朴的介绍一下。 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: The detailed model can be found on our company's website 2. Medium temperature: the minimum and maximum temperature of the measured liquid Know which liquids are made up. 4. Task pressure: What is the minimum pressure? 5. Measurement scale: that is, the center distance between two flanges. 6. Flange specification: Nominal diameter of the flange. 7. Wetted material: If you do n’t know which material to use, you can Ask us 7. Special request: Can you bring remote transmission, insulation jacket, electric heat tracing, etc.
