Turbine flow meter5/2/2024 ![]() Turbine flowmeters should not be operated at high velocity because premature bearing wear and/or damage can occur. Make sure to operate these flowmeters above approximately 5 percent of maximum flow. Turbine flowmeters are less accurate at low flow rates due to rotor/bearing drag that slows the rotor. Application Cautions for Turbine Flowmeters 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. Miscellaneous applications are found in the food and beverage, and chemical industries. Petroleum applications include the custody transfer of hydrocarbons. Water applications include distribution systems within and between water districts. The flow of corrosive liquids can be measured with proper attention to the materials of construction of all wetted parts, such as the body, rotor, bearings, and fittings.Īpplications for turbine flowmeters are found in the water, petroleum, and chemical industries. Smaller turbine flowmeters can be installed directly in the piping, but the size and weight of larger turbine flowmeters may require the installation of substantial concrete foundations and supports. This flowmeter can be applied to sanitary, relatively clean, and corrosive liquids in sizes up to approximately 24 inches. In addition, turbine flowmeters that are designed for a specific purpose, such as for natural gas service, can often operate over a limited range of temperature (such as up to 60✬) whereby operation at higher temperatures can damage the flowmeter. Some turbine flowmeters have grease fittings for use with non-lubricating fluids. These flowmeters often incorporate the functionality of a flow computer to correct for pressure, temperature and fluid properties in order to achieve the desired accuracy for the application.īe careful using turbine flowmeters on fluids that are non-lubricating because the flowmeter can become inaccurate and fail if its bearings prematurely wear. High accuracy turbine flowmeters are available for custody transfer of hydrocarbons and natural gas. Turbine flowmeters measure the velocity of liquids, gases and vapors in pipes, such as hydrocarbons, chemicals, water, cryogenic liquids, air, and industrial gases. They do cause some pressure drop where that may be a factor such as gravity flows. AGA and API approved for custody transfers. They are reliable if put in a clean fluid especially if it has some lubricity. ![]() Turndown is very good as it can read very low compared to the maximum flow. Very good at clean, low viscosity fluids of moderate velocity and a steady rate. Transmitters and sensing systems are available to sense flow in both the forward and reverse flow directions. The transmitter processes the pulse signal to determine the flow of the fluid. When the fluid moves faster, more pulses are generated. 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. Blade movement is often detected magnetically, with each blade or embedded piece of metal generating a pulse. ![]() Shaft rotation can be sensed mechanically or by detecting the movement of the blades. Turbine flowmeters now constitute 7% of the world market. ![]() When the fluid moves faster, the rotor spins proportionally faster. Blades on the rotor are angled to transform energy from the flow stream into rotational energy. Turbine flowmeters use the mechanical energy of the fluid to rotate a “pinwheel” (rotor) in the flow stream.
