Wellbar Flow Sensor

Brief Introduction:

Wellbar Flow meter is a flow metering system consisting of an integrated Wellbar sensor, a differential pressure transmitter and an integrating instrument etc. and it can be connected to a control system or a computer to form a network so as to conduct fluid flow measurement and control.
It can offer precise and stable differential pressure signals, strong strength, seepage resistance and clogging resistance. The sensor can ensure features, The flowmeter can be used to measure multiple fluids, including gas, liquid, steam and corrosive media.
 

Details:
Measurement Precision: 0.5% ~ 1.0 %
Repeatability Precision: 0.1 %
Application Pressure Range: 0~25Mpa, in special application
it can be up to 40Mpa.
Application Temperature Range: -100 ~ 500 , in special
application it can be up to 800 .
Measurement Upper Limitation: It depends on the requirements of craft and the strength of detector.
Measurement Lower Limitation: It depends on the requirement of the lowest measurement differential pressure (shown in the following table). When it is less than the lowest measurement differential pressure, it can meet the requirement by special design.

Fliud        Lowest differential pressure    Flow rate
Gas         0.026Kpa                              4.5 m/s
Liquid      0.260 Kpa                             0.6 m/s
Steam     0.400 Kpa                             9.7 m/s
 
Measurement Range Ratio: When the measurement precision is 0.5%~ 1.0 %, the Measurement Range Ratio is 10:1.
In special application, it can be 60:1.
Application Tube Diameter Range: 8mm~ 15000mm.
Applicable Medium: full package, unidirectional gas, steam, and liquid with viscosity not more than 10 centipoise.
Requirement of Straight Tube Section: Usually the measurement precision of the first 7D, last 3D should be 0.5%~ 1.0 %.
