The intelligent integrated vortex flowmeter integrates flow, temperature, and pressure sensors. In addition to retaining all features, it adopts modern microprocessing technology and can measure the standard state flow or mass flow of gas and steam without the need to cooperate with a flow integrator through a liquid crystal display on site (i.e., automatic temperature and pressure compensation on site). Vortex flow transmitter is mainly used for flow measurement of industrial pipeline fluid media, such as gas, liquid, steam and other media. Its characteristics are small pressure loss, large range, high accuracy, and almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring volumetric flow rate under working conditions. No movable mechanical parts, therefore high reliability and low maintenance. The instrument constant can remain stable for a long time. Plug in instruments are installed at the insertion port of the pipeline, while ball valves can be continuously loaded and unloaded. To facilitate regular cleaning and maintenance when operating in dirty media. This instrument uses piezoelectric stress sensors with high reliability and can operate within a temperature range of -20 ℃ to+250 ℃. It has both analog standard signals and digital pulse signal outputs, making it easy to use in conjunction with digital systems such as computers. It is a relatively advanced and ideal flow meter.
