Due to the special advantages that vortex flowmeters possess, which are unmatched by other types of flowmeters, they are widely used for measuring the flow rate of fluids in industrial pipelines, including various media such as gases, liquids, and vapors. However, when it comes to fluid control, the following steps should be taken: During operation, the platinum wire sensing element is heated using direct current, resulting in a temperature that is about 20°C higher than the temperature of the liquid. As the fluid flows past the element, an alternating pressure difference is generated on either side of it. Under the influence of this pressure difference, the fluid is drawn in and blown out, which leads to a decrease in the temperature of the heating wire and consequently a reduction in its resistance. This disrupts the balance of the measurement bridge, resulting in the generation of a voltage signal. After being amplified, this voltage signal increases the DC supply voltage to the bridge circuit, thereby raising the heating current of the heating wire and allowing its temperature to return to its original level. When vortices separate alternately, alternating pressure waves are generated on both sides of the generating body, forcing the fluid to be drawn in through the main and auxiliary pressure holes on one side of the generating body, pass through the heat wire sensing element, and then be blown out through the main and auxiliary pressure holes on the other side, thereby enabling the detection of vortex separation signals. An internal cavity is created, with a partition wall installed therein; a platinum wire sensing element is placed in the groove of the partition wall. To improve the response speed of the sensing element, its heat capacity and time constant should be reduced, which is why the platinum wire is very thin. By controlling the separation point of the fluid boundary layer, on the suction side, the separation of vortices from the main pressure hole to the auxiliary pressure hole is effectively controlled. On the ejection side, vortices begin to form at the primary pressure hole, and they are significantly intensified as they move downstream toward the auxiliary pressure holes. For ease of use, the battery-powered local display type vortex flow meter utilizes low-power advanced technology; powered by lithium batteries, it can operate continuously for over a year. This reduces the costs associated with purchasing and installing cables and display instruments, and it allows for the on-site display of instantaneous flow rates, cumulative flow, and other parameters.
