Classic venturi tube also can named classical venturi tube.
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 charateristic
♦ 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’s proceed to real flow calibration
Technical parameters
♦ Taking pressure mode:Upstream use the span taking-pressure,downstream 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 : 2x 10³x 10³ ≥ReD≥ 2x 10³x 10²
efflux coefficient C:C=0.985
