annubar flowmeter

 annubar flowmeter

Yjanb series annubar flowmeter ( It is also called flute type velocimeter and Toba tube flowmeter, belonging to differential pressure flowmeter ) Annubar flowmeter is mainly used for the measurement of various energy sources such as liquid, fuel gas, steam and gas in the industrial process. The product mainly uses the pitot tube measurement principle to measure the pressure difference formed between the dynamic pressure at the upstream of the baffle and the static pressure at the downstream, so as to achieve the purpose of measuring the flow. The diameter of the measuring pipe is between 0 DN20 reach DN12000 between. It has high stability and repeatability.
 Working principle of Annubar flowmeter

At present, Annubar flowmeter is widely used in the flow measurement of blast furnace gas, compressed air, steam and other liquids and gases in industrial and mining enterprises.


 

Yjanb series annubar flowmeter Main features:

1. The unique internal quadratic average structure provides high accuracy (reading ± 0.9899% )And high repeatability (± 0.09999% )。

2. The outer impact pipe is made of a whole piece of material without welding. Compared with the similar products welded by double body structure, the outer impact pipe has the highest strength and is easy to select high temperature and corrosion resistant materials.

3. The honeycomb hexagonal stable structure produces a unique beam distribution shape, which ensures the stability of low-pressure signal, the differential pressure generated is higher than that of similar products, and the range ratio is improved.

4. Suitable for square or rectangular pipes.

5. For similar products in the measurement of dirty media, there are on-line pull-out type or provide manual and automatic purging scheme and device to realize maintenance without production stop.

6. Pitot + Three valve group + Temperature and pressure compensation + The transmitter is of integrated structure and easy to use.

7. No flow coefficient drift, long-term stability.

8. It provides intuitive resonance checking calculation exclusively to ensure long-term stable operation.

9. Small pressure loss, low energy consumption and remarkable energy saving effect

10. Easy installation, labor saving, low price and quick delivery

 

Yjanb series annubar flowmeter Technical parameters:

 

1. It is suitable for measuring the flow rate of liquid, gas and steam

2. The accuracy is ± 0.9999%

3. The repeatability of the measurement was ± 0.9989%

4. The range ratio of flow rate, typically for ten one (differential pressure value one hundred one

5. The maximum working temperature is up to one thousand and three hundred C (with proper materials and mounting parts)

6. Maximum working pressure up to 400Bar 40MPa

7. The highest viscosity is 500 cp

8. The length of upstream and downstream straight pipe is required to be short

9. Long term accuracy is not affected by wear and tear
