Clamping
vortex flow meters come in the form of pipeline and plug-in flow sensors,
without movable components, stable and reliable, with flexible and convenient
installation methods. According to the on-site process pipeline, they can be
installed horizontally, vertically, and at different angles with inclination
Vortex
flow meter is a volume flow meter that measures the volume flow rate, standard
volume flow rate, or mass flow rate of gas, steam, or liquid d on the
Karman vortex flow principle. Mainly used for flow measurement of industrial
pipeline medium fluids, such as gases, liquids, steam, and other media. It can
also measure turbid liquids containing small particles and impurities, and is widely
used in industries such as petroleum, chemical, pharmaceutical, ermaking,
llurgy, power, environmental protection, and food.

output of the sensor is a pulse frequency, which is linear with the actual flow
rate of the measured fluid, with zero drift, stable performance, and diverse
structural forms
