主要用于各种行业工业管道中大口径气体、液体、蒸汽介质流体的流量测量, 插入式涡街流量计特点是压力损失小,量程范围大,精度高,在测量工况体积流量时几乎不受流体密度、压力、温度、粘度等参数的影响。 DXLUCB plug-in vortex flowmeter is mainly used for flow measurement of large-caliber gas, liquid and vapor medium fluids in industrial pipes in various industries. It is almost independent of parameters such as fluid density, pressure, temperature and viscosity when measuring working volume flow. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. 采用压电应力式传感器,可靠性高,可在-20℃～+250℃的工作温度范围内工作。 The plug-in vortex flow uses a piezoelectric stress sensor with high reliability and can work in the operating temperature range of -20 ° C to + 250 ° C. It has analog standard signal and digital pulse signal output. It is easy to be used with digital systems such as computers. It is a relatively advanced and ideal flow meter. .
防爆型，符合GB3836-83《爆炸性环境用防爆电气设备》的有关规定，防爆标志为ExdIIBT6。 DXLUCB plug-in vortex flowmeter explosion-proof type, in line with GB3836-83 "Explosion-proof electrical equipment for explosive environments", the explosion-proof mark is ExdIIBT6.
According to the International Organization for Standardization IS07145 (Determination of fluid flow in a closed section of a circular pipe—speed measurement method at one point of the section), a vortex street speed probe embedded in a piezoelectric crystal is inserted into a large-diameter industrial pipe to convert the frequency of Carmen vortex It is a current or voltage pulse signal or a 4-20mADC current signal that is proportional to the flow rate.
