Turbine flow meters are flow sensors work for the inline liquids.

Turbine flow meters are cost-effective and offer reliable,

measurement with minimal flow meter maintenance required.

Turbine flow meters measure the velocity of liquids, gases, and vapors in pipes,

such as hydrocarbons, chemicals, water, cryogenic liquids, air, and industrial gases.

Turbine Flow Meter Working Principle

Turbine meters are simple to operate and maintain,

and in-service worldwide as a reliable, cost-effective method,

for achieving accurate flow measurement.

Turbine flow meters are designed to maximize throughput,

and minimize pressure drop, maintain high flow rates over an extended flow range,

and offer pulse output that is linear to the flow rate.

The turbine meters also minimize fiscal measurement uncertainty,

by delivering high-frequency pulse resolution,

to account for minute increments of the flow rate.

Turbine flow meters use the mechanical energy of the fluid to rotate a “pinwheel” (rotor) in the flow stream.

Blades on the rotor are angled to transform energy,

from the flow stream into rotational energy.

The rotor shaft spins on bearings.

When the fluid moves faster, the rotor spins proportionally faster.

Turbine flow meters now constitute 7% of the world market.

Shaft rotation can be sensed mechanically or by detecting the movement of the blades.

Blade movement is often detected magnetically,

with each blade or embedded piece of metal generating a pulse.

Turbine flowmeter sensors are typically located external to the flowing stream,

to avoid material of construction constraints that would result,

if wetted sensors were used.

When the fluid moves faster, more pulses are generated.

The transmitter processes the pulse signal to determine the flow of the fluid.

Transmitters and sensing systems are available to sense flow,

in both the forward and reverse flow directions.

Turbine flow meter equation

The relationship between volumetric flow rate of the turbine flowmeter and the frequency of the pulses generated by the pickup sensor can be expressed in the form of the equation:

f = kQ

Where,
f = Frequency of pulses generated by pickup sensor(Hz, equivalent to pulses per second)
Q = Volumetric flow rate (e.g. litres/min)
k = “K” factor of the turbine meter (e.g. pulses per litre)

The turbine meter measures volumetric flow, however the pulses produced vary depending on the meter. The variation is accounted for by a K-factor. The K-factor is the number of pulses per unit volume. It is primarily determined by the size and type of the turbine meter. Due to manufacturing tolerances, the actual K-factor can vary between similar models. The K-factor is applicable only to the fluid for which the meter was calibrated in the factory.

Turbine flow meter advantages and disadvantages

Advantages of Turbine Flow Meters

1. High precision, generally up to ± 1% R, ± 0.5% R.
2. Output pulse frequency signal, suitable for total metering and connection with a computer, no zero drift, strong anti-interference ability.
3. Compact and lightweight, easy installation and maintenance, and large-circulation capacity.
4. Good repeatability, short-term repeatability of 0.05 ~ 0.2%, due to good repeatability, frequent calibration or online calibration can get very high precision.
5. A special type of sensor can be designed according to user needs, such as low-temperature type, two-way, downhole type, mixed sand special type.
6. Pressure compensation can be performed under the pressure state in which the gas to be measured is stable.
7. The turndown is wide, medium and large caliber up to 1:20, small-caliber is 1:10.

Disadvantages of Turbine Flow Meters

1. Need to be calibrated regularly, there is no way to maintain accuracy for a long time, can not work continuously for a long time.
2. The cleaning requirements of the medium are high, but the filter can be installed.
3. The flowmeter has a large influence on the flow velocity distribution (flow regulator can be installed).
4. It is not suitable for places where the flow rate is drastically changing.
5. Not suitable for testing of corrosive media.
