Classic 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
