Turbine flow meter working principle ppt. They will not be linear at reynolds numbers nearing or in the laminar region. Working principle types installation and everything else 3 minutes to read the turbine flow meter is one of the most accurate flow meters available and as such one of the most common in fiscal applications such as custody transfer for petroleum. The angular velocity of the rotor results in the generation of an electrical signal ac sine wave type in the pickup. A permanent magnet is encased in the rotor body and each time the rotating magnet pass the pole of the pickup coil working principle of turbine flow meter 118.
It works on the principle of turbine. Turbine flow meter use a free spinning turbine wheel to measure fluid velocity much like a miniature windmill installed in the flow stream. Turbine flow meter working principle. The flowmeter is a volumetric measuring turbine type.
The turbine flow meter principle is used for the measurement of liquid gas and gases of very low flow rate. It consists of a multibladed rotor called turbine wheel which is mounted 90 to the axis of the flowing liquid as shown in fig. The flowing fluid engages the rotor causing it to rotate at an angular velocity proportional to the fluid flow rate. Turbine flow meter the fundamental design goal of.
Turbine flow meter is a volumetric measuring turbine type. Turbine flow meters figure 2 are inherently sensitive to reynolds number. Big money products need very accurate meters. The typical accuracy and repeatability of turbine flow meters are 0 5 and 0 1 respectively.
However it is possible to achieve accuracy of 0 25 and repeatability of 0 05. Working principle of turbine flow meter.
