LUGB type vortex flowmeter is according to the principle of Carmen (Karman vortex street measuring gas, steam or the volume of liquid flow, the volume of the standard condition or volume flow to mass flow meter. And can be used as flow transducer is applied to automatic control system.Vortex flowmeter can be divided according to function name gas flow meter,flue gas meter,steam flow meter,gas flow meter,compressed air flow meter,liquid flow meter. The instrument adopts the advanced differential technology, cooperate the measures such as isolation, shielding, filtering, overcome the similar products such problems as poor vibration resistance, small signal data disorders, using a unique sensor encapsulation technology and protective measures, to ensure the reliability of the product. Products are both basic and compound type, basic measuring single traffic signal; Compound can be realized at the same time temperature, pressure, flow rate measurement. Each type has overall, fission structure, in order to adapt to different installation environment. Vortex flowmeter classification: LUCB series plug-in vortex flowmeter, LUCB series of vortex flowmeter is mainly used for industrial piping medium fluid flow measurement, such as gas, liquid and vapor, and other media. Is characterized by small pressure loss, wide range, high precision, working condition of the measurement volume flow is almost not affected by the fluid density, the influence of the parameters such as pressure, temperature, viscosity. No moving mechanical parts, so high reliability, small amount of maintenance. Instrument parameters can be long-term stability. Vortex street flowmeter using piezoelectric stress sensor, high reliability, can be in - 20 ~ + 250 temperature range. There are standard signal simulation and digital pulse signal output, easy with the computer and digital systems, is a more advanced, the ideal flow meter.
