9ED-500H metal tube is commonly used in industrial automation and process control of a flow measurement instruments, it has a small pressure loss, detection range （10:1 turndown）, easy to use features, it can be used to measure liquid, gas and steam flow, especially suitable for low velocity flow measurement of small flow media. 9ED-500H metal tube with local display and inligent remote type, with the pointer shows the instantaneous flow, cumulative flow, liquid crystal display, upper and lower limit alarm output, accumulated pulse output, the standard two-wire 4-20mA current output and other forms, to provide users with a very broad choice. In addition to the instrument microprocessor MCU with high-quality system to ensure a flow meter place in the excellent performance of various applications. Over the years a variety of fine metal tube flowmeter performance and reliability, and better cost performance by the wide range of petrochemicals, iron and steel, electric power, metallurgy, light industry of all ages.
