More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the working principle of the Verabar flowmeter and the details of its application articles. 1. Product overview of JTHLV Verabar flowmeter: JTHLV Verabar flowmeter adopts an engineering structure design that fully conforms to the principle of aerodynamics. Flow meters are suitable for high-precision flow measurement of gases, liquids and steam. The low-pressure hole of the JTHLV Verabar flowmeter achieves essential anti-blocking. Generally, dust, sand and particles are concentrated at the back of the probe under the action of vortex force. This is why fall foliage is always concentrated behind a leeward house. For other probes, the low-pressure pressure-taking hole is located in the vacuum area at the end of the probe. Under the action of the vortex street force, the low-pressure pressure-taking hole of the probe is quickly blocked by impurities brought by the eddy current. The unique design of the Verabar flowmeter makes the low pressure take-off holes located on the rear two sides of the probe side, in front of the fluid separation point and the wake area. This design essentially prevents clogging and produces a very stable low voltage signal. 1. Application of Verabar flowmeter JTHLV Verabar flowmeter is a differential pressure and rate average flow sensor, which measures flow through the differential pressure generated by the sensor in the fluid. The Verabar flowmeter reflects the real flow rate of the fluid, and its accuracy reaches± 1.1111, repeatability up to± 0.1111. The outstanding advantages of Verabar are: output a very stable, pulsation-free differential pressure signal 2. Design features of the probe The probe with the cross-sectional shape of the probe can produce precise pressure distribution and a fixed fluid separation point; it is located on the back and rear sides of the probe, and the fluid is separated. The low pressure tap hole before the point can generate a stable differential pressure signal and effectively prevent clogging. The internal integrated structure can avoid signal leakage, improve the structural strength of the probe, and maintain long-term high precision. 3. Verabar probe anti-blocking design With its excellent anti-blocking design, the Verabar flow probe completely gets rid of the drawbacks of plug-in flow probes such as Annubar that are easy to block, making the anti-blocking level of the uniform velocity tube flow probe to an unprecedented level. high. The probe's high-pressure pressure hole will not be blocked to form a high-pressure area at the front of the probe, and the pressure is slightly higher than the static pressure of the pipeline, preventing particles from entering. Please note: The velocity of the fluid at the high pressure tap hole of the probe is zero and no object will enter the tap hole. When the machine is turned on, the fluid enters the elbow under the action of the static pressure of the pipeline, and soon forms a state of pressure balance. When the pressure equilibrium state is formed, the fluid encounters high pressure at the inlet of the elbow, detours, and no longer enters the elbow. 4. Advantages of the probe ● It can measure a variety of media and has a wide range of applications ● High accuracy and large range ratio ● The probe pressure hole is essentially anti-blocking ● The measurement signal is stable and the fluctuation is small ● The pipeline pressure loss is low ● The unique high-strength probe Single-piece double-chamber structure ● Low installation cost, basically maintenance-free ● Can be installed and repaired online Between the probe separation points, away from the eddy current fluctuation area. ● Excellent long-term high precision Verabar can ensure long-term stability of accuracy because: ⑴. It is not affected by wear, dirt and oil. ⑵. There are no moving parts in the structure. ⑶. The design eliminates the occurrence of clogging. At the front of the probe, a high static pressure area surrounds the probe so that the high pressure tap hole will not be blocked. The most important thing is that the low-pressure holes are taken on the back two sides of the probe side, and the fluid swept across the surface obliquely, which protects the low-pressure holes from being swept, and other probes are easily blocked because their low-pressure pressure-taking holes are where impurities gather. Low pressure fluctuation area. ● Lowest installation cost ⑴. Only need a few inches of line welding, the installation is very simple and fast. ⑵. The application of special tools can realize on-line installation under pressure. ⑶. All valves and interfaces of various instruments only need simple assembly, requiring very low assembly costs. ● Very low operating cost ⑴. It is a non-contraction throttling design, as a plug-in flow probe, the operating cost of Verabar is the lowest. ⑵. Verabar flowmeter only produces very low permanent pressure loss, typically less than 0.7KPa ⑶. The permanent pressure loss generated by an orifice element exceeds 14KPa⑷. Compared with the orifice plate, the energy loss of Verabar is reduced by 95% . ● The continuous working Verabar fundamentally eliminates the possibility of blocking, but in the following cases, Verabar should still pay attention to preventing blocking: ⑴. When the pressure pipe leaks, the high pressure balance area of ​​the probe is destroyed, and the diameter of impurities is small The particles are likely to enter the tap hole. ⑵. When the pipeline is shut down, due to the Brownian motion of the molecules, impurities with small particles may enter the pressure tapping hole. ⑶. The system is frequently turned on and off. At the moment when the high-pressure area is formed, impurities with small particles may enter the pressure-taking hole, and over time, it may cause the blockage of the probe.
