Applications for turbine flowmeters are found in the water, petroleum, and chemical industries. Water applications include distribution systems within and between water districts. Petroleum applications include the custody transfer of hydrocarbons.
Miscellaneous applications are found in the food and beverage, and chemical industries. In order of magnitude from largest to smallest, these are used in oil and gas, water and wastewater, gas utility, chemical, power, food and beverage, aerospace, pharmaceutical, metals and mining, and pulp and paper. Make sure to operate these flowmeters above approximately 5 percent of maximum flow.
Be careful when measuring fluids that are non-lubricating because bearing wear can cause the flowmeter become inaccurate and fail. In some applications, bearing replacement may need to be performed routinely and increase maintenance costs. Application in dirty fluids should generally be avoided so as to reduce the possibility of flowmeter wear and bearing damage.
In summary, turbine flowmeters have moving parts that are subject to degradation with time and use. These conditions generally occur when filling the pipe and under slug flow conditions.
Two-phase flow conditions can also cause turbine flowmeters to measure inaccurately. Turbine flow meters measure the velocity of liquids, gases and vapors in pipes, such as hydrocarbons, chemicals, water, cryogenic liquids, air, and industrial gases.

Field calibratable. Includes non-volatile totals. High accuracy meter Internal parts are simple to replace for easy maintenance AAA Alkaline battery life: 2 years. Turbine flowmeters are used to monitor clean liquids in chemical, petrol and water industries. For example, when used by water companies to transport water through long distances, they measure how fast the water is moving and can alert the companies to any problems or breakdowns.
While there are many different factors that affect the lifespan of turbine flowmeters, the average lifespan should be many years. You need to maintain and clean the turbine flowmeter regularly to make sure there is no grit or debris that can cause problems in the flow stream.
Mainly the life expectancy depends on the size of the turbine and what it is being used to measure. The cost of manufacturing turbine flowmeters is actually fairly low, this means that the cost is low at the point of sale. A turbine flowmeter can move clean fluids, which have a low viscosity such as water very easily and have a very low risk of breakdown or problems.
Turbine flowmeters can also be used with other low viscosity fluids but the rate of breakdown or problems increases if you use a more viscous fluid.
Used with the right liquids, they are a very reliable system. They are a simple design, which is easy to understand and therefore not difficult to keep maintained and working. They perform well and are easy to install and operate. Problems can occur if installation is not done carefully and correctly, and it will need checking often to make sure calibration is correct. One of the main problems you might find with a turbine flowmeter is not with the blades itself, but the bearings that sit at the end of the central rod.
These bearings need to be working fully to make sure the turbine is performing as it should and you are getting accurate readings from the internal sensor.
Your flowmeter should also be checked for corrosion and if there are any signs of the metal corroding, then it should be removed and replaced as soon as possible. This will prevent further damage happening to your system. As the bearings are the part of the flowmeter which can wear out the quickest, make sure they are regularly inspected and maintained. The rotor sits on a shaft ,which in turn is suspended in the flow by the two supports.
As the media flows, a force is applied on the rotor wings. The angle and shape of the wings transform the horizontal force to a perpendicular force, creating rotation.
Therefore, the rotation of the rotor is proportional to the applied force of the flow. Because of this, the rotor will immediately rotate as soon as the media induces a forward force. As the rotor cannot turn thru the media on its own, it will stop as soon as the media stops. This ensures an extremely fast response time, making the Turbine Flow Meter ideal for batching applications.
A pick-up sensor is mounted above the rotor. When the magnetic blades pass by the pickup sensor, a signal is generated for each passing blade. This provides a pulsed signal proportional to the speed of the rotor and represents pulses per volumetric unit. Make sure to operate these flow meters above approximately 5 percent of maximum flow. Be careful when measuring fluids that are non-lubricating because bearing wear can cause the flow meter become inaccurate and fail.
In some applications, bearing replacement may need to be performed routinely and increase maintenance costs. Application in dirty fluids should generally be avoided so as to reduce the possibility of flow meter wear and bearing damage.
