Turbine Flow Meter

Turbine flow meters work by allowing the fluid to impinge upon turbine blades/rotors which move freely on an axis. This rotating motion generates an electrical signal whose frequency is proportional to the rate of flow. The advantages of Nagman’s Turbine Flow meters are :-

Product Details


A turbine flow meter is a device used to measure the flow rate of liquids and gases. It operates on the principle of a spinning rotor or turbine placed in the fluid stream. The rate at which the rotor spins is directly proportional to the flow rate.
Turbine flow meters are commonly used in various industries, including water treatment, petrochemicals, pharmaceuticals, and food processing. They are suitable for measuring the flow of clean, low-viscosity fluids.
Turbine flow meters offer high accuracy and repeatability. They can handle a wide range of flow rates, are compact, and are suitable for both liquid and gas applications. They are also relatively easy to install and maintain while being cheaper than flow meters like Electromagnetic.
Factors to consider include the fluid type, viscosity, flow range, temperature, pressure, and any potential abrasives or corrosive properties. It's crucial to choose a meter that is compatible with your specific application requirements.
Turbine flow meters are best suited for low-viscosity fluids. For high viscosity liquids, other types of flow meters, such as positive displacement or electromagnetic, may be more suitable. The minimum and maximum flow rates depend on the specific meter model.
