Which turbine flowmeter is better

Which turbine flowmeter is good is a question often asked by customers at the purchase stage. Now, there are many manufacturers of turbine flowmeters in the country. Everyone who wants to buy turbine flowmeters hopes to lower the cost. To purchase higher-quality turbine flowmeters, however, the prices and quality of turbine flowmeters on the market now vary widely. This poses a lot of risk for buyers and users.　　 Turbine flow meters are velocity flow meters, also called impeller flow meters. The impeller flowmeter uses the proportional relationship between the rotational angular velocity of the impeller placed in the fluid and the fluid flow rate. It reflects the volume flow of the fluid through the pipeline by measuring the speed of the impeller. It is one of the more mature high-accuracy meters in the flow meter. one. Turbine flowmeter is generally composed of the following typical five parts: 　　1. Meter body The material of the meter body is generally steel or cast iron, and its two ends are flanged. Small-diameter meters also use threaded connections.　　2. Measuring component 　　 There are precision-machined blades on the turbine, which together with a set of reduction gears and bearings form a measuring component. The two high-precision stainless steel permanent self-lubricating bearings that support the turbine ensure a long service life. Turbine flowmeter can also use external lubricating oil pump to lubricate the bearing, but pay attention not to exceed it. 3. There are the following important information on the counter panel: 　　 (1) Maximum operating temperature and pressure: 　　 (2) Measurement and minimum and maximum flow rate (3) Product model and serial number (4) Explosion-proof grade and mark (5) Low frequency or high The equivalent of the fluid corresponding to the frequency pulse and the wiring method.　　4. Rectifier 　　The rectifier is used to make the fluid flow through the turbine flowmeter in a regular state, so as to eliminate the unprofitable influence of the disturbance on the measurement. High measurement accuracy.　　5. Magnetic coupling transmission device 　　This device separates the counter part in the atmosphere from the gas to be measured, and transmits the rotation of the measuring component to the counter.　　 When we choose the turbine flowmeter, we can compare the five components to find the most suitable and cost-effective turbine flowmeter.　　 For example, for the watch body, we generally judge whether it is good or bad from the angle of weight, welding, etc. Generally good turbine flowmeters are relatively heavy and thick. In addition, the welding of the meter body can also see the quality of the manufacturing process, so as to indirectly judge the quality of the flowmeter.　　 Kaidi Turbine Flowmeter has the following two main characteristics: 　　 1. One-piece forming, fine steel milling. The impeller is integrally processed and formed to ensure the balance, linearity, long-term stability and consistency of the impeller. Front and rear double guide structure, streamlined guide frame, fluid rectification is not disordered. High-quality stainless iron, 2205 duplex steel material, impeller anti-corrosion and non-oxidation.　　2. Standards beyond the standard. EMC electromagnetic compatibility test, Kaidi standard exceeds industry standard 1500V, exceeds enterprise standard 1000V. The converter has power-down protection measures, and the power-down data can be stored for up to ten years. Internal circuit isolation, external all metal isolation.　　 Generally, in the selection of turbine flowmeters, in addition to satisfying the parameters, the main consideration is the process life of the product and the company's guarantee. Kaidi Sensing has achieved both of these two points. Therefore, in comparison with turbine flowmeters, Kaidi turbine flowmeter is the best choice.
