Vortex flowmeter is based on the Karman (Karman) vortex principle of research and production, mainly used for industrial pipeline media fluid flow measurement, such as gases, liquids, vapors and other media. It is characterized by small pressure loss, large range, high accuracy, in the measurement of the volume flow of the working condition is almost independent of the fluid density, pressure, temperature, viscosity and other parameters, there is no movable mechanical parts, so high reliability, low maintenance, instrument parameters can be stable for a long time. Vortex flowmeter adopts piezoelectric stress type sensor, high reliability, can be in -20 ℃ ~ +250 ℃ working temperature range. There are analog standard signal and digital pulse signal output, easy to use with computers and other digital systems, is a more advanced, ideal measuring instruments.

Vortex flowmeter is currently one of the main international flow meter production, widely used in petroleum, chemical, rubber, heat, metallurgy, electric power, pharmaceutical, textile, printing and dyeing and other industrial sectors, as well as municipal construction, environmental protection projects. The implementation of the liquid (water, alcohol, low viscosity oils, beverages, seasonings and chemical liquids), gas (air, oxygen, ammonia, natural gas and coal gas and other gases) and steam (saturated steam, superheated steam) of the flow measurement, calorimetric measurement and detection and control.
