The flow meter is used to measure the flow of the water, gases, and many more environmental factors. It has different applications and can be used for different environmental applications.
Different types of flow meters
Magnetic flow meter: It is a volumetric flow meter that does not contain any moving parts and ideal for wastewater applications and dirty liquid which is water-based or conductive. Magnetic flow meter will work with distilled water and hydrocarbons. It uses Faraday’s law of electromagnetic induction that can measure the process flow. It uses sound waves to find the velocity of the fluid flowing in the pipe.
Turbine flow meter: This flow meter translates the mechanical action of the turbine and rotates in the liquid flow into user readable flow rate. It tends to have the flow traveling around. The fluid impinges on the blades of the turbine and imparts the force to blade surface and set the rotor in the motion. These flow meters are used for measuring liquid flow and natural gases. These are less accurate than the jet meters.
Vortex flow meter: The method of flow measuring involves the placement of the bluff body in the fluid path. When the fluid passes the bar, it disturbs the flow called vertices. The vortices trail behind of the cylinder and from each side of the bluff body. The frequency at which the vortices alternate sides is very essential proportional to the flow rate of the fluid. The sensor of the tool is piezoelectric crystal and which produces a small and measurable voltage pulses when the vortex is created.
Oval gear meter: It is positive displacement flow meter that is used for two or more gears configured to rotate right angles to one another forming T shape. These meters have two sides which are called A and B. Fluid does not pass the center of the meter where the teeth of both gear meshes. On one side of the meter, the teeth close off the fluid because the gear on side A protrudes into the measurement chamber. On another side, cavity holds a fixed volume of the fluid measurement chamber.
These are different flow meters which are used in the market and there are many more meters which are used for different applications. You can choose the flow meter as per your requirement.
