Work Introduction
When the fluid flow through the KEWDB Wei Diba flow probe, in its front to produce a high-pressure distribution, high pressure distribution pipeline pressure slightly higher than the static pressure.
Bernoulli equation based on the principle of fluid flow through the probe speed faster, the rear of the probe to generate a distribution area of ??low pressure, low pressure distribution pipeline slightly lower than the static pressure. Fluid flow from the probe after the probe produce a partial vacuum the back and sides of the probe appears in the whirlpool.
KEWDB Wei Diba flow cross-sectional shape of the probe, the surface roughness condition and location of the hole to take pressure low is a key factor in the decision performance of the probe.
Stable and accurate low-voltage signal flow probe on the Wei Diba play a decisive role in the accuracy and performance.
Wei Diba flow probe can be accuray detected by the fluid produced by the average speed of the average differential pressure value.
Wei Diba flow probe in the high and low pressure are arranged according to certain criteria for multi-hole pressure to take on the special process to make it possible to accuray detect the average velocity.
KEWDB Wei Diba qualitative analysis of flow probe
Design features: shape of a special process sub-probe
KEWDB Wei Diba flow sensor using cross-section shapes such as bullet-shaped probe, corrosion resistant stainless steel integrated double cavity structure. High-pressure form the front of the probe hole high pressure zone, can prevent the fluid particles into the hole to take pressure and low pressure in the probe lateral holes on both sides of the fluid separation point with the probe before the holes were blocked to reduce the possibility of low-voltage . In the front surface of the metal probe, carried out treatment process, according to aerodynamic theory, the fluid flow through the surface, forming a stable turbulent boundary layer, enabling the state to improve the measurement accuracy of low flow, so fluid at low flow rate, probe can be stable and accurate differential pressure signal, thus extending the lower limit of the sensor measurement range, to maintain stability factor.
KEWDB Wei Diba design flow probe anti-clogging
KEWDB Wei Diba aiming to halt the flow probe is its excellent design, compley out of the plug-flow probe easy to plug the shortcomings, the KEWDB Wei Diba attempts to prevent the flow performance to probe the only advanced level.
KEWDB Wei Diba 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. The probe hole to take pressure of high pressure fluid velocity is zero, the object will not take pressure into the hole.
Just-machine, static pressure in the pipe under the action of the fluid into the pipe, and 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 pipeline.
KEWDB Wei Diba flow probe to achieve low-voltage nature of attempts to prevent the hole to take pressure
In general, dust, sand and particles in the vortex under the action of force, focusing on the back of the probe. Other probes the low end of the probe hole to take pressure vacuum zone, the force of vortex force, the probe of the low-pressure vortex hole quickly bring the impurities to be blocked.
KEWDB Wei Diba unique flow sensor 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 is essentially to prevent the blockage and can generate a very stable low-voltage signal.
Orifice flow meter and compared KEWDB Wei Diba save a lot of installation costs
For example: DN250 Wei Diba flow meter installed on the pipeline, welding the hole just 35mm, the same pipeline, the installation plate 160M is required welding pipe flanges, saving at least 95 compared Wei Diba % of installation costs, is easy to see the bigger diameter, KEWDB Wei Diba flow sensor is installed on more cost savings.
KEWDB Wei Diba compared flowmeter and orifice pressure drop
KEWDB Wei Diba is a typical differential pressure flow meter, industrial production is used to measure gas, liquid and steam flow only the most advanced flow meter,
Some industries are still using the plates, nozzles, Venturi tubes, multi-throat diameter and V-cone, and other cutting pieces, cutting pieces to minimize eddy current around the area, thereby reducing the fluid pressure damage, but in fact the contrary, it increases consumption energy.
KEWDB Wei Diba bullet-shaped flow meter used advanced technology, making it not only maintained a high-precision flow measurement, high intensity and large range ratio. Also greatly reduce the pressure loss makes the pipe, or pressure loss is almost zero, even micro pressure loss through the inligent model program directly into the flow of energy saving effect.
