Industry Information
Verabar flowmeter is located between the fluid behind the probe side and the separation point of the probe

探头的优点: Advantages of Verabar flowmeter probes:
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 inherently anti-blocking; the measurement signal is stable and the fluctuation is small; the permanent pressure loss of the pipeline is low; the unique high-strength bullet-shaped single-chip dual-cavity Structure; low installation cost, basically maintenance-free; can be installed and repaired online.
The characteristics of the Verabar averaging tube flow sensor are stable signals; Verabar's low pressure pressure taking holes are located on the back of the probe side, between the fluid and the probe separation point, away from the vortex wave area. Verabar guarantees 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 occurrence of blockage is excluded from the design. At the front of the probe, a high static pressure area surrounds the probe so that the high-pressure pressure taking hole will not be blocked. The most important thing is that the low-pressure holes are taken at the back two sides of the probe side, and the fluid is swept across the surface, which protects the low-pressure holes from being swept, and other probes are easily blocked because their low-pressure pressure holes are collected by impurities. Low voltage fluctuation area.
最低的安装费用:⑴. 只需要进行几英寸的线条焊接,完成安装是非常简单和快捷的。 The lowest installation cost of Verabar flowmeters : ⑴. Only a few inches of line welding are needed, and the installation is very simple and fast. ⑵. Apply special tools to achieve online installation with pressure. ⑶. All valves and interfaces of various instruments need only simple assembly, which requires very low assembly costs. (4) It is a non-constricting design. As a plug-in flow probe, Verabar has the lowest operating cost. (5) Verabar produces only very low permanent pressure loss, typically less than 0.7KPa (6) Permanent pressure loss generated by an orifice plate element exceeds 14KPa (7) Compared with orifice plates, Verabar energy loss Reduced by 95%.
Continuous operation of Verabar basically eliminates the possibility of plugging, but in the following cases, Verabar still needs to pay attention to preventing clogging: ⑴. When the pressure tube leaks, the high-pressure balance area of the probe is damaged, and the smaller diameter of the impurities Particles may enter
Pressure hole. ⑵. When the pipeline is stopped, due to the Brownian motion of the molecules, small particles of impurities may enter the pressure taking hole. ⑶. The system frequently starts and stops. At the moment when the high-pressure area is formed, small particles of impurities may enter the pressure taking hole. Over time, the probe may be blocked. ⑷. The medium contains a large amount of tar, algae, or contains fibrous substances, which may also cause the probe to be blocked.
Application of new technology original design of valve joints with valve ... The new design concept provides a new concept, built-in instrument stop valve at the joint of the instrument, making installation and maintenance easier. ⑵. Reduce the number of assembly parts and reduce the cost of hardware connection.
Verabar flowmeters are fast and easy to install: 1. The sealed drive system can avoid damaging the components 2. Can be applied to the installation of multiple probes separately 3. The entire installation does not exceed 1 hour

传感器特点 Verabar Flowmeter Sensor Features

1, can measure a variety of media, a wide range of applications

Measuring medium range: liquid, gas, steam

Measuring tube diameter range: 8mm-1200mm

Measuring pressure range: generally 0-210kqf / cm2, special applications up to 420Kqf / cm2

Measuring temperature range: general -100-505 ℃, special applications up to 805 ℃

2.Excellent long-term accuracy

Verabar's accuracy is ± 0.5- ± 1.0%, repeated test accuracy is ± 0.1%, and the output signal is non-pulsating signal, which is particularly stable because it has no moving parts on the structure; the low-pressure hole will not be blocked and a stable signal will be taken. ; Flow coefficient (K value) is linear and does not change with Reynolds number and flow rate like the orifice plate nozzle type.

3.Permanent pressure loss of the pipeline is small

Verabar's cross-sectional shape has the lowest resistance, so the permanent pressure loss of the fluid is the lowest, generally only 3% of the differential pressure. Compared with orifice plates, nozzles, and venturi, the energy consumption is reduced by more than 95%. Energy consumption, you can recover the entire investment.
