1、Verabar overview

JGHLV Verabar in full compliance with the aerodynamic design of engineering structures, is a kind of precision, efficiency and reliability has reached unsurpassed levels of sensor components。

1、Verabar purposes
Verabar for gas, liquid and steam flow measurement accuracy. Verabar is a differential pressure, the average rate of flow sensor, the sensor in the fluid flow generated by the difference reflects the true velocity, the accuracy of ± 1.0, repeatability ± 0.1. Pakistan is the power of the outstanding advantages: a very stable output, no differential pressure fluctuation signal

2 、Design features of the probe
Bullet cross section of the probe to produce accurate pressure distribution, a fixed flow separation point; lateral sides located on the probe, the fluid pressure before the separation point to take pressure holes, can generate a stable differential pressure signal, and effective attempts to prevent. Internal integrated structure to avoid signal leakage and improve the structural strength of the probe to maintain long-term accuracy。

3.Pakistan probes anti-blocking design of the power of the power of Pakistan's attempts to prevent the flow probe is its excellent design, and so completely out of Annubar easy to plug the plug-flow of the shortcomings of the probe so that the average rate of attempts to prevent the flow of the probe reached an unprecedented high level。

High Pressure from the probe hole is not blocked high-pressure front of the probe area, the pressure slightly higher than the static pressure pipes to prevent the particles to enter. Please note: the probe hole to take pressure of high pressure fluid velocity is zero, no object will enter the hole to take pressure. Boot, under the static pressure of fluid in the pipe into the elbow, soon formed a pressure balance. After the formation when the pressure equilibrium, the fluid pressure in the pipe met the entrance, take a detour, not into the bend。

Verabar nature of attempts to prevent the realization of low pressure holes under normal circumstances, dust, sand and particles in the vortex under the action of force, focusing on the back of the probe. This is why autumn leaves are always concentrated in the lee of the reasons behind the house. Other hole pressure probe to take the low end of the probe to take the vacuum area, the role of vortex force, the probe of the low pressure holes were quickly taken to bring the impurities Eddy blocked. Verabar unique design, the low pressure measuring holes located on both sides of the probe lateral, fluid separation point and the front of the wake region. This design prevents the plug from nature and can produce a very stable low-voltage signal。

4.Advantage of the probe
● Measure a variety of media, wide range of applications
● High precision, range ratio
● Nature of attempts to prevent the hole to take pressure probe
● Measurement signal stability, low volatility
● Low permanent pressure loss pipe
● Unique bullet-shaped high-intensity single-chip dual-chamber structure
● Low cost of installation, basic maintenance
● Online installation and maintenance

5.Power barThe average rate of flow sensor characteristics
● Stability of the signal
Power barPressure from low-voltage lateral holes in both sides of the probe, the fluid between the separation point with the probe away from the vortex fluctuation region。
● Excellent long-term accuracy
威力巴To ensure the accuracy of long-term stability, it is because：
⑴. It is not subject to wear, dirt and the impact of oil pollution。
⑵. Structure, no moving parts。
⑶. Designed to eliminate the clogging phenomenon. The front of the probe, high static pressure zone around the probe, the high pressure measuring hole will not be blocked. Most importantly, low lateral hole to take on both sides of the probe, the fluid from the surface Rake over, protect the low pressure holes will not be swept, and the other probe prone to clogging because of their low pressure measuring holes in the impurity aggregation Low volatile region。

● The lowest installation costs
⑴. Requires only a few inches of the weld lines to complete the installation is very simple and quick。
⑵. Application-specific tools, can be achieved with pressure-line installation。
⑶. All valves and instruments just a simple interface assembly, the assembly need to be very low cost。

● Very low running costs
⑴.It is a non-shrink cutting the design, as a plug-flow probe, the power bar is the lowest operating costs。
⑵.VerabarProduced only very low permanent pressure loss, typically less than0.7KPa
⑶. Components generated by a permanent orifice pressure loss over14KPa
⑷.Compared with the plate, the power of Pakistan's energy consumption reduced95。

● Continuous work Pakistan power to fundamentally eliminate the possibility of blocking, but in the following cases, still pay attention to the power of Palestinian attempts to prevent：
⑴. When the cited pressure tube leak, the destruction of the probe pressure balance area, impurities in the smaller diameter of the particles is likely to enter the access
压孔。
⑵. When the pipe is cut, due to the Brownian motion of molecules, small particles of impurities are likely to get pressure into the hole。
⑶. The system shut down frequently open, high-pressure area formed in the moment, the small particles of impurities are likely to enter to take pressure holes, over time, it may cause blockage of the probe。
⑷. Medium contains a lot of tar, algae, or contain fibrous material, may also cause blockage of the probe。

6 、Application of new technologies
Original design of the connector with valve power bar...The new design offers a new concept, built-in instrument instrument valve joints
1 . So much easier to install and maintain。
2 . Reduce the number of assembly parts to make the hardware connection
Cost reduction。

Quick installation system
Quick insertion and removal
● Sealing drive to avoid damage to components
● Can be applied to multiple probes were installed
Full installation of not more than1 Hours
