Turbine flow meters are volumetric in-line sensor to detect gas or liquid flow rate; it detects low to middle flow rate, clean, low corrosive and viscosity fluids. Turbine flow metre is divided into gas turbine flow meter and liquid turbine flow meter. Silver Automation Instruments supply electronic turbine meter with a variety of outputs, such as frequency, current for PLC or batch dispensing operation. It can take measurement of fuel, gasoline, diesel, water, RO water, milk, natural gas, biogas, compressed air and so on.
It is operated with simple well understood technology; measured medium is going to the sensor body, making the rotor to rotate at a speed proportional to medium velocity and flow rate. As each blade passes through the magnetic field generated by the flow meter’s magnetic pickup, an alternating current voltage pulse is produced.

Flowmeters works in various ways and it measures different elements. Therefore,in this article i have provided everything that will help you to understand more about turbine flowmeter. The design is comprehensive and it will help you to get more insight about its funtionalituy. Read on and find out.

turbine flow meter working?

There is a shaft that is mounted inside inline turbine flow meter to support the other. This helps in minimizing negative turbulence attack. The support provided also houses the open bearings which allow for lubrication of the brushes hence prolonging the lifespan of the turbin flow meter. These supports have locking rings that are used to fasten it.
The shaft plays a crucial role in supporting the rotor. Therefore, when there is a flow it induces a force on rator wings which will, in turn, rotate because its shape and angle enhance force. Additionally, there is a mounted turbine flow transmitter above the rotor which generated signals for passing blades. The sensors located externally to the glowing stream to avoid the occurrence of constraints in a case whereby wetted sensors are used. The pulse signal which is processed by the flow transmitter is used in determining the flowrate of the liquid or gas. The sending and transmitter systems sense the forward flow directions.
The most important element that keeps it to move freely is the propeller located in the tube. This turbine flowmeter has been designed to ensure there is little drop in pressure hence it is regarded as one of the best measurement tools.

Turbine flow meter price

Turbine flow meter price is determined by many factors
a. Gas turbine or liquid turbine flow meters are different
b. Different turbine flow meter sensor size ,different price
c. Different turbine flow transmitters, different cost, such as whether need digital turbine flow meter , whether need HART or RS485.
d. High temperature or high pressure also affect turbine flow meter price a lot

Turbin meter Manufacture

There are many top brands turbin flow meter factories, such as cameron nuflo turbine meter,blancett flow meter,daniel turbine meter,omega turbine flow meter,badger turbine meter,helical turbine meter,Emerson turbine flow meter,k24 electronic turbine meter, they are rugged turbine flow meters with not cheap price .However Silver Automation Instruments sell economical flow meters as alternative or low price replacement.

turbine flow meter accuracy

SGW Gas turbine flow meter with accuracy 1.5% or 1.0%,liquid turbine flow meter with accuracy 0.5~1.0%

How to operate

It takes flow measurements on velocity of gases and liquids. A functionality flow computer can be used to correct the temperature, pressure and fluid properties that ensure the desired accuracy is achieved. Non-lubricating fluids can wear out its bearing and it influences the flowmeter to lose its accuracy levels. However, some have grease fittings that allow them to be used with non-lubricating fluids. Additionally, these turbine Flowmeters are designed to operate with a limited temperature range of up to 60 c which implies it is susceptible to being damaged when exposed to a temperature that exceeds this value.
It is used for liquids up to 10 inches (DN250 Turbine flow meter). The weight and the size of a larger turbine might require supports and concrete foundations.. When dealing with corrosive fluids Attention should also be paid to materials, such as fittings, bearings, rotor, and body.
Chemical, petroleum and water industries largely use turbine Flowmeters. Some chemical, food, and beverage industries can also use this type of Flowmeters. It serves custody of the transfer of hydrocarbons in the petroleum industry and a distribution system for water plants. We often use this flow instrumentation as natural gas flow meter, diesel flow meter, fuel flow meter.,etc

Industries where turbine flow meter used

Turbine Flowmeters are used in the following industries as per the largest to the smallest magnitude.
-Oil and gas
-Water and wastewater
-Gas utility
-Food and beverage
-Pulp and paper

Application and Risks

The accuracy is compromised at slow flow rates. Therefore, there is a need to ensure the flowmeter is operated at above 5 %. High speeds can also lead to wearing out. Non-lubricating fluids can also make it less accurate that is why you should be cautious enough to avoid such inconveniences. It should also not be used I dirty fluids to reduce occurrences of bearing damage.
It can get damaged or become less accurate when there is an abrupt transition from gas to liquid flow. This scenario can occur when it is under slug flow or filing the pipe. You should also avoid two-phase flow because there will be inaccurate measurements. Gas turbine flow meter and liquid turbine flow meters are different, customers should specify the fluids when buy the turbine flow meter to the manufacture.
If you are unfortunate enough to experience some breakdowns with your flowmeter you need to choose replacements wisely. You should look at the levels of accuracy that you need. It is better to settle on an expensive but reliable system.
Lastly, before you purchase ensures it has a warranty in case of unexpected breakdowns. Most cases that have led to breakdowns is using it the wrong way. As I had earlier said that Non-lubricant are kit recommended because it makes this system to lose its accuracy. Therefore,it is important to use it for the right purpose to ensure you get reliable and accurate results.
