Function

1. The body also integrates temperature and pressure compensation function, which can measure the standard volume flow rate or standard mass flow rate of the fluid..

2、 Fully intelligent and digital circuit design, capable of automatically compensating for measured fluid density or standard condition volume calculation.

3、 The new digital filtering and correction functions make flow measurement more accurate and reliable.

4、 The battery powered type can work continuously for more than two years without the need for an external power source.

5、 The brand new dot matrix Chinese character LCD display is more convenient to use and operate. /iknow-pic.cdn.bcebos.com/cf1b9d16fdfaaf5171634bd2835494eef11f7adf"target="_blank"title=" Click to view large image "class=" ikqc_img.link ">/i know pic.cdn. bcebos. com/cf1b9d16fdfaaf5171634bd2835494eef11f7adf?

When used for other media, the available flow range will vary depending on the viscosity and density of the medium. As the oil flow standard device uses diesel with a viscosity greater than water and a density smaller than water as the calibration medium, the lower limit flow rate of the flow meter will generally be correspondingly increased, narrowing the available flow ran

ge. Therefore, it is normal for the vortex destruction grip flow meter to have poor performance at small flow rates when calibrated on the oil flow calibration device. Therefore, it is not difficult to infer that if liquefied petroleum gas (this low viscosity medium) is used to calibrate the flow rate of the fiber scraper vortex street, this concept flow meter will obtain a flow rate that is higher than water. Good opposite result.

The vortex flowmeter is a fluid natural oscillation instrument developed based on the principle of "Karman vortex street". Its core is to calculate the flow rate by detecting the vortex frequency generated by the fluid when it bypasses obstacles.. The following is a detailed explanation of its working principle.

1. Definition of Karman vortex street phenomenon: When a fluid (gas or liquid) passes around a non streamlined obstacle (such as a triangular column or cylinder), two columns of vortices are alternately generated on both sides downstream of the obstacle. The arrangement of vortices is similar to the street lights on both sides of the street, hence it is called "vortex street". Discoverer: This phenomenon was mathematically derived and experimentally verified by aerospace engineer von Karman, hence it is also known as the "Karman vortex street". Key characteristics: The frequency of vortex generation (f) is linearly related to the fluid flow velocity (v) under specific conditions, that is, the higher the flow velocity, the faster the frequency of vortex shedding
