Turbine Flow Meter Overview:
A turbine flow meter is a volume sensing device. As liquid or gas passes through the turbine housing, it causes the freely suspended turbine blades to rotate. The velocity of the turbine rotor is directly proportional to the velocity of the fluid passing through the flow meter.
The external pickoff mounted on the body of the flow meter, senses each rotor blade passing, causing the sensor to generate a frequency output. The frequency is directly proportional to the volume of the liquid or gas.
Either a magnetic or modulated carrier (RF) pickup can be used to sense the rotational speed of the turbine rotor.
Depending on your flow meter application, there are many types of turbine flow meters to choose from. And after understanding the application several factors come into effect when choosing a flow meter, such as:
- Fluid Type
- Pipe Sizing
- Process Temperature (min & max)
- Flow Range (min & max)
- Pressure Range (min & max)
- Accuracy Range
- Specific Application
If you need volumetric total flow and/or flow rate measurement, a turbine flow meter is the ideal device. Turbine flow meters are used in a wide variety of liquid and gas flow sensing applications. They can be built to endure high pressure, and high and low temperatures. They offer a high turn-down with minimum uncertainty and excellent repeatability. Turbine flowmeters are also simple to install and maintain only requiring periodic recalibration and service.
Accuracy is generally expressed as a percentage of true volume, measuring how close the instrument indicates actual flow.
Repeatability is determined on how well the flow meter can indicate the same reading whenever the same flow conditions exist. It also ensures quality measurement of fluids over a wide range of flow rates, temperatures, compositions and viscosities.
Depending on the type of turbine flow meter, the specifications vary.

I need the one that will be used for LPGas line to meter all the product recieved
Thank you for reaching out to us at Flowmetrics. Our FM series turbine flow meter will do this for you. What line size and flow rates are you using for your LPG process?
Can Turbine flowmeters be used during Gas Lift applications
Hi Aniedi, thank you for commenting. Yes, our turbine flow meters can be to measure the gas or liquid going in or coming out of the well during the lift process. Check out the turbine meter product page. We have more information on our product there along with data sheets for download. Feel free to email me at email@example.com if you have anymore questions.
Can your turbine meter give a linearity of +/- 0.15%?
Hello Isaac, that is a pretty low linearity. We are typically at +/-0.5% over normal range given a 10:1 turndown. You can check out all the specs of our turbine meters on the product page or download the FM Series data sheet from the downloads page. Let me know if you have anymore questions.
what is the price for DN25 turbine flow meter for oil ?
Hello there and thank you for contacting us at Flowmetrics. The exact price would depend on a number of factors like process connection, pickup type and so on. Email us at firstname.lastname@example.org with all of your specifications and we can provide you with a quote.
Does turbine flow meter require any straight pipe run, ? and is it applicable to use for Airflow measurement in 16 inch pipe dia.?
Hello Ashok, thank you for contacting Flowmetrics. It is best practice to have a minimum of 10x the diameter upstream and 5x the diameter downstream for optimal flow development. The largest inline turbine meter we manufacture is 12″. For your 16″ pipe one of our insertion turbine meters can be used. You can learn more about these on our website under the turbine flow meter product section. The FMP series is our insertion flow meter product. Should you have any additional questions, please feel free to email us at email@example.com. Have a great day!
Can you offer sanitary flow meter
Hello Lily and thank you for contacting us at Flowmetrics. We offer our turbine flow meters with a sanitary connection up to 2″ in size. Let us know if you have any further questions, you can email us at firstname.lastname@example.org. Have a great day!
Can i use this turbine flowmeter for CaOh application?
Hello Shariff! Thank you for contacting us at Flowmetrics. CaOH is normally in a powder form and our turbine flow meters are intended for liquids or gasses. That being said, if the CaOH is suspended in a liquid and flows thought the meter as a slurry, then yes, our meter should suit your needs. Please provide more information via our quote form and I will be able to provide you with a quote. If you have any further questions, you can always reach us at email@example.com
