been widely used in industrial sections such as chemical industry, chemical
fiber, metallurgy, chemical fertilizer, paper making, water supply and drainage,
sewage treatment, etc. and in automatic control of the production process.
9.2. Product form and composition
The product type is magnetic insertion. It is connected with the pipeline through a
mounting base, a ball valve, a compression nut and a positioning screw. Sensor
measurement can be divided into two types of structure: measurement tube type
and plane electrode type. The measuring tube type sensor is suitable for
measuring the cleaning medium; the planar electrode type is suitable for
measuring the liquid flow rate containing other impurities in the medium.
