Purging equipment is mainly used for hydrostatic level measurement, static pressure and differential pressure density measuring or flow measurement. Traditional methods apply the combined use of metal tube valve and constant valve to make purging equipment. But in the modern industrial sector, we often encounter problems of high temperature, high pressure or corrosive media condition, therefore we requires the use of metal tube rotameter to proceed. After several on-site practical applications, the purging equipment made by metal tube rotameter can be used in petroleum refining and purging process control of transmitter in chemical and other industries stably and reliably.

　Metal tube rotameter as a part of flow measurement unit, its technical parameters can determine the technical characteristics of purge equipment: Measuring unit material: 316L or 316 or medium temperature, flow range, control pressure range, field indicators of flow and pressure, you can install the switch signal or the signal transducer and so on.

　As a high-tech product, especially in the case of small flow pipe, it has good prospects for use. At present, metal tube rotameter is mainly used to prevent liquid in petroleum, chemical, steel, electricity, and other industries and gas flow and automatic control systems.
