Anuba flowmeter (also known as flute shaped averaging tube flowmeter and Toba tube flowmeter) is the same asperforated plate、spray nozzleLike throttling devices, it also belongs to differential pressure flow meters. According to the Bernoulli equation principle,When fluid flows through the probe,Create a high-pressure distribution area in its front,The pressure in the high-pressure distribution area is slightly higher than the static pressure of the pipeline. Fluid flows through the probeIncrease the speed of time,Create a low-pressure distribution area behind the probe,The pressure in the low-pressure distribution area is slightly lower than the static pressure of the pipeline. After the fluid flows through the probe, a partial vacuum is generated at the back of the probe,And vortices appear on both sides of the probe. The cross-sectional shape, surface roughness, and low pressure of the uniform flow probeThe position of the pressure hole is a key factor determining the performance of the probe. The stability and accuracy of low-voltage signals play a decisive role in the accuracy and performance of the uniform velocity probe. The Annubar equal velocity flow probe can accurately detect the average differential pressure generated by the average velocity of the fluid.The Anuba uniform velocity flow probe has multiple pairs of pressure tapping holes arranged according to certain criteria in the high and low pressure zones,Make it possible to accurately measure the average flow velocity. It uses the principle of pitot tube measurement to measure the pressure difference between the dynamic pressure upstream of the blocking body and the static pressure downstream, in order to achieve the purpose of measuring flow rate.Measure the diameter of the pipelineDN20arriveDN12000between. Anuba flowmeter is mainly used for measuring various energy sources such as liquids, fuel gases, vapors, and gases in industrial processes,Has high stability and repeatability. Anuba flowmeter is availableJG/640－90Conduct inspections according to regulations.
