LZ-50 remote transmission metal tube float flowmeter

Description :

　　LZ-50 remote transmission metal tube float flowmeter

　　This product is a metal structure float flowmeter suitable for measuring liquids and gases. The float moves upward under the action of fluid and buoyancy, and after balancing with the weight of the float, it is transmitted to the dial through magnetic coupling to indicate the corresponding flow rate, which can output a 4-20mA electrical signal.

　　3、 Questions to note when selecting:

　　(1) When selecting a float flowmeter, the first step is to understand the product standards implemented by the metal tube float flowmeter manufacturing enterprise, especially the regulations on accuracy and display scale. Secondly, it is necessary to understand the manufacturing and technical level of the product. At the same time, it is necessary to combine the process requirements in flow measurement, especially in situations where high measurement or control accuracy, intuitive scale display, and high medium viscosity are required, to choose a float flowmeter that can directly display the medium flow rate and has density and viscosity compensation performance.

　　(2) Master accurate process conditions and provide accurate medium parameters. Because the conversion and verification of scales are based on the medium conditions:

　　(3) Select appropriate materials for measuring components. Generally, it is necessary to choose measurement materials with good anti-corrosion performance. Only by ensuring that the float and measuring components are not corroded by the medium for a long time, can the accuracy requirements of the product during long-term operation at the factory be guaranteed.

　　(4) It is necessary to choose a range that can keep the normal working flow rate within 50% to 80% of the full scale. If the normal working flow rate is lower than 50% of the n-range, the absolute error at the measurement point will increase, which is not conducive to control accuracy.
