1.system composition
l Annubar Flow meter’s system is composed by three parts:
l a part of secondary source: the probe of verabar transducer
l the transiducer parts of differential conversation: differential pressure transmitter or flow transducer
l flow display part: flow integrator or PLC/DCS systems
2. main technical indicator
l Working pressure: 0～ 40MPa
l Working temperature: -180 ～ +550°C
l measurement accuracy：±1%
l repeatability：±0.1%
l material of sensor：304、316L or special customized
l pipeline size：DN38 ～ DN15000 round tube or square tube
l range than：10:1
l measurement range：the measured upper and lower limits allow the minimum differential pressure.
the minimum flow and differential pressure of verabar Flowmeter
| Medium | Flow rate | The minimum differential pressure |
| Gas | 3.5m/s | 0.025kpa |
| Liquid | 0.6m/s | 0.25kpa |
| Steam | 9.0m/s | 0.38kpa |
Annubar Flowmeter is apply for measuring many kinds of medium: full pipe, uniflow, the single gas, steam and viscosity less than 10 centipoise liquid, like:
l The primary and secondary wind measurement for power plants
l Blast furnace gas measurement
l Compressed air measurement
l The gas, nitrogen, oxygen and other measurement
l Ethane, ethylene, such as natural gas measurement
l Saturated steam, high and low voltage measurements
l Tap water, circulating water measurement, etc
4.Main characteristics and advantages
l simple structure, light weight
Verabar of the Flowmeter is composed by a hollow metal tube, pressure tube and pipe joint. This is simple structures that only have about 10 components.
l Easy to install and teardown, low free
l low pressure loss, saving energy
l Many applications of medium and widely measurement
It can be used in all kinds of fluid (gas, liquid, steam). The diameter is from 38mm to 6000mm,and the upper limited pressure is40 Mpa, the upper limited of temperature is 550°C or more.
l high accuracy and good long-term stability
There is no moving parts, the accurate is not influenced by sticky dirty and corrosion.
l low requirement for straight pipe
Because of multiple test holes, this has gone down the requirements for straight pipe.
l can installation an maintenance online
l Probe design concept and unique advantages
l Power probe using warhead design
l Probe high strength single double cavity design
