A turbine flow meter is a widely used tool for measuring the rate of flow of a given fluid. It works on the principle that a turbine or a device similar to it rotates in a constant rate when a fluid is passing through it. Any kind of measurement device affixed to it can measure the given rate of flow to provide the required reading.
Turbine flow meter is a device for measuring the volumetric flow rate of gases or liquids passing through a pipeline per unit of time. Turbine consists of a shaft, which is fixed in the pipeline and an impeller. Such impeller is multi-bladed wheel. That wheel is attached to a shaft that rotates on bearings.
Turbine Flow Meter: Technology and Working Principle
From petrochemical to wastewater treatment, flow measurement is an integral part of many industries. There are several ways to measure flow, each using a different type of technology. Some examples include mechanical, electromagnetic, turbine and vortex flowmeters. While these traditional methods are highly useful, they are not always the best option for the application. In certain situations, traditional flow measurement tools with moving parts or intrusive pieces may be undesirable. Many applications could benefit from a flow measurement technique that is non-invasive and long-lasting. Ultrasonic flowmeters fit these requirements perfectly.
Remember Me. One type of flow meter that can be used for various liquid or gas flow measuring and monitoring applications across multiple industries is the turbine-based flow meter. You may have already come across turbine flow meters in your research, but what exactly are turbine flow meters used for and how do they work? Turbine flow meters utilize the Pelton turbine wheel concept, which uses a miniature turbine wheel supported on a very small sapphire shaft held in position by two sapphire bearings. Because the wheel and shaft are extremely lightweight, the turbine wheel virtually floats in the liquid passing through, relieving the force on the shaft and bearings and eliminating wear. Simple to install, operate and manage, turbine flow meters leverage mechanical energy from the flow sample to rotate the wheel in the flow stream.
Advantages & Disadvantages of Different Flow Meters
Electromagnetic flow meters - or induction flow meters - function with conductive fluids by measuring flow across a controlled magnetic field. With orifice flow meters the pressure difference over an orifice in the flow is measured. Measured pressure difference is proportional with flow velocity squared. Turbine flow meters are made with bladed turbine rotors mounted axially in the meter. When fluid flows through the meter the rotor spins at a speed proportional to the velocity of the fluid.

Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. The common types of flowmeters with industrial applications are listed below:. Flow measurement methods other than positive-displacement flowmeters rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow.
What is a turbine flow meter? Turbine flow meter advantages and disadvantages Turbine Meter Advantages The cost is moderate. Very good at clean, low viscosity fluids of moderate velocity and a steady rate. Turndown is very good as it can Read More.
The Turbine Flow meter Principle is used for the measurement of liquid gas and gases of very low flow rate. It works on the principle of turbine. The rotor is supported by the ball or sleeve bearings on a shaft which is retained in the flow meter housing by a shaft support section. The rotor is free to rotate about its axis.
Turbine flow meter advantages and disadvantages
A flow meter is a device that measures the flow rate of a fluid. Flow meters are flow measuring instruments used to measure the linear, nonlinear, mass, or volumetric flow rate of a gas or a liquid. Flow meters are also known as Flow Gauges. This article will provide the following information in short:. Volumetric flow meters got its name because these flow meters measure the fluid volume passing through a specific location in a set period of time. Volumetric flow meters provide an instantaneous analog, digital, or pulse output of the volumetric flow rate of the liquid or gas.
- Я хочу быть абсолютно уверен, что это абсолютно стойкий шифр. Чатрукьян продолжал колотить по стеклу. - Ничего не поделаешь, - вздохнул Стратмор. - Поддержи. Коммандер глубоко вздохнул и подошел к раздвижной стеклянной двери. Кнопка на полу привела ее в движение, и дверь, издав шипящий звук, отъехала в сторону. Чатрукьян ввалился в комнату.
