Techincal Support

Fuel flow meter is a flow meter used to measure the flow rate of fuel-based media. Generally, a fuel flow meter refers to an oval gear flow meter or a turbine flow meter.

 

Oval gear flowmeter is used as fuel flowmeter.

Oval gear flowmeter is a volumetric measuring instrument. Oval Gear flow meter is mainly composed of a measuring housing, an oval gear rotor and transmission components. Instrument for continuous or intermittent measurement and control of liquid flow in pipes.

Turbine flow meters are used as fuel flow meters.

Turbine flowmeter is also a type of speed flow meter, which is the main variety of impeller flow juice (also water meters, anemometers, etc.). It uses a certain proportional relationship between the impeller rotation speed and the fluid flow rate placed in the flow field and. Measures the flow rate by detecting the impeller rotation speed.
Turbine flowmeters have high accuracy, low pressure loss, and high pressure resistance. They are widely used in the flow measurement of petroleum, organic liquids, inorganic liquids, liquefied gases, natural gas, coal gas, and low-temperature fluids.
With the development of electronic technology and its application in the instrument industry. New turbine flow meters such as plug-in turbine flowmeters and fiber-optic turbine flowmeters have appeared one after another. The range ratio of turbine flowmeters has further increased and bidirectional measurement can be achieved. Its application prospect is promising. .

 

Different flowmeters have different working principles. For example, the working principle of vortex flowmeter is Carmen vortex street. And the working principle of electromagnetic flowmeter is Faraday’s law of electromagnetic induction. Principle to confirm its measurement medium.
The working principle of the turbine flow meter:
Fluid flows through the sensor housing.
Because the blade of the impeller has a certain angle with the flow direction, the impulse of the fluid causes the blade to have a rotating moment.
Blades rotate after overcoming frictional torque and fluid resistance.
After the torque is balanced, the speed is stable.
Under certain conditions, the speed is directly proportional to the flow rate.
Because the blade is magnetically permeable, it is in the magnetic field of a signal detector (made of permanent magnetic steel and coils).
The rotating blade cuts the magnetic field lines and periodically changes the magnetic flux of the coil.
Thereby, an electric pulse signal is induced at both ends of the coil.
This signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude.
Remotely transmitted to the display instrument, show the instantaneous flow rate and cumulative amount of the fluid.
In a certain flow range, the pulse frequency f is proportional to the instantaneous flow Q of the fluid flowing through the sensor.

Flow meter calibration is the process of comparing the pre-set scale or metering of a flow meter to a standard scale of measurement. And adjusting its metering to conform to the standard. Calibration is an essential aspect of instrumentation in a broad range of industries that require high-accuracy measurements with a negligible percentage of error.
E.g. in Oil & Gas, Petrochemical, and manufacturing.


Generally, there are two types of flowmeter calibration: online calibration and offline calibration.
On-line calibration does not need to remove the flow meter to achieve the calibration under the online flow state. This method is not very accurate, but calibration can probably be performed with an ultrasonic flow meter.


The other is off-line calibration. This method has high accuracy, but the flowmeter must be removed for calibration by the manufacturer, or brought to the metrology institute for calibration.


Flow meters are calibrated by comparing and adjusting their metering to correspond with a predefined standard. Flow meter manufacturers typically calibrate their products in-house after production or send them to an independent calibration facility for adjustment.
