LUGB series vortex flowmeters (Cheap) 
 First, an overview 
 LUGB series vortex flowmeter is a fluid natural vibration principle for the development of a new type of flowmeter. The series vortex flowmeter has a simple structure, no mechanical moving parts of see, reliability, accuracy, repeatability, flow rate range and temperature range, pressure loss, the test cycle is long and so on. 
 Second, the characteristics 
 LUGB series of vortex flowmeters within the specified range of Reynolds numbers from the influence of fluid temperature, pressure, viscosity and composition used for the detection piezoelectric element does not contact the fluid, suitable for harsh environments, while not blocking, not card, difficult to scaling, high temperature, high pressure, safety explosion-proof, suitable for measuring the closed pipe liquid, gas, and steam cumulative flow and instantaneous flow. LUGB series vortex flowmeters are widely used in oil field, petrochemical, machinery, light industry, metallurgy, pharmaceutical, paper and urban water supply, heating, gas and other industries in the field of industrial process control, energy management and environmental engineering as a flow meter and control instruments. Integration LUGB series vortex flowmeter Remote Display, and can output the pulse signal or current signal and computer networking.
