Velbar flowmeter

Velbar flowmeterSuitable for high-precision flow measurement of gases, liquids, and vapors. The Weiliba flowmeter is a differential pressure and rate averaging flow sensor that measures flow by measuring the differential pressure generated by the sensor in the fluid. The Velbar flowmeter reflects the true flow velocity of the fluid, with an accuracy of ± 1.0 and a repeatability of ± 0.1. The outstanding advantage of Weiliba is that it outputs a very stable and pulsation free differential pressure signal

Design features of the probe:
A probe with a cross-sectional shape can generate precise pressure distribution and a fixed fluid separation point; The low-pressure tapping holes located on both sides behind the probe and before the fluid separation point can generate stable differential pressure signals and effectively prevent blockages. The internal integrated structure can avoid signal leakage, improve the strength of the probe structure, and maintain long-term high accuracy.

Powerbar probe anti blocking design:
Velbar flowmeterThe probe, with its excellent anti blocking design, completely eliminates the disadvantage of easy blockage of insertion flow probes such as Anuba, and achieves an unprecedented level of anti blocking for the averaging tube flow probe. The high-pressure tapping hole of the probe will not be blocked, forming a high-pressure zone at the front of the probe. The pressure is slightly higher than the static pressure of the pipeline, preventing particles from entering. Please note that the fluid velocity at the high-pressure tapping hole of the probe is zero, and no object will enter the tapping hole. When starting up, the fluid enters the bend under the static pressure of the pipeline, quickly forming a state of pressure equilibrium. After the pressure equilibrium state is formed, the fluid encounters high pressure at the inlet of the bend, detours and no longer enters the bend.

Velbar flowmeterIn general, dust, sand, and particles are concentrated at the rear of the probe under the action of vortex force to achieve intrinsic anti blocking of the low-pressure hole. That's why autumn leaves always gather behind windward houses. Other probes have low-pressure pressure tapping holes located in the vacuum zone at the tail of the probe. Under the action of vortex forces, the low-pressure pressure tapping holes of the probe are quickly blocked by impurities brought by eddy currents. The unique design of the Weiliba flowmeter allows the low-pressure tapping holes to be located on both sides of the probe side, at the front of the fluid separation point and wake area. This design fundamentally prevents blockage and can generate a very stable low-voltage signal.
