What are the advantages of turbine flow meters? Posted by : admin / Posted on : May 05, 2022

Turbine flowmeters use the mechanical energy of the fluid to rotate the "windmill" (rotor) in the flow of water. The blades on the rotor are tilted, converting the energy of the fluid flow into rotational energy. The shaft rotates on the bearing. As the liquid moves faster, the rotor spins faster. Currently, turbine flowmeters account for 7% of the global market.

Shaft rotation can be detected mechanically or by detecting the movement of the blades. Blade movement is detected magnetically, and each blade or embedded metal sheet generates a pulse. Turbine flowmeter sensors are generally located outside the flow, avoiding the structural limitations of wet sensors. As the liquid flows faster, more pulses will be generated. The transmitter processes the pulse signal to measure the liquid flow. Sensors and sensor systems can be used to detect flow in both forward and reverse directions.

The cost is not high. Clean, low viscosity, medium speed, stable speed liquid use. Low frequencies are good because it reads very little and has a lot of flow. When used, such as when using clean liquids, especially when lubricating, it should be reliable. AGA and API are approved for trade handover. They do cause some pressure drop, like gravitational flow, etc. Dangerous vapors.

Turbine flow meters are used to measure fluids, gases and vapors such as hydrocarbons, chemicals, water, cryogenic liquids, air and industrial gases. Precision turbine flow meters can be used for oil and gas and custody transfer of oil and gas. Turbine flow meters of this type typically include flow computer functionality for correcting pressure, temperature, and fluid properties to the required accuracy.

Use caution when using a turbine flowmeter in the absence of lubricant, as it can become inaccurate and fail if it wears out prematurely. Some turbine flow meters are also equipped with a grease engagement device. In addition, turbine flowmeters designed for specific uses (such as natural gas facilities) generally operate in a limited temperature range (such as up to 60°C), so operation at high temperatures can damage the flowmeter.
