Detailed Description

Classic venturi tube also can named classical venturi tube.Its design manufacture and use are conform to the national standard ISO5167 or GB/T2624 rules.It often used calculated in the flow of liquid and gas. Main characteristic Simple structure,fastness,performance stable; The pressure loss is small; Structure size is large, and installation size is long; No need real flow calibration, precision correct, when need the precision is higher,then it is proceed to real flow calibration. Technical parameters Taking pressure mode:Upsteam use the span taking-pressure, downsteam use the laryngeal taking-pressure; Nominal pressure:≦6.3MPa; Caliber:50~2200mm; Accuracy(indeterminacy):+/-1.5%; Range of application:open hole diameter rate β:0.4≦β≦0.7 Reynolds number range ReD:2*106≧ReD≧2*105 Efflux coefficient C:C=0.985
