Turbine Flowmeter

A turbine flow meter consists of a turbine with specific blades, along with a sensor, such as a proximity switch. Each rotation of the turbine, caused by the flow of the fluid, generates a series of pulses. By calibrating the device according to the flow rate and the number of pulses produced, the flow meter's range can be determined.  

Insertion

In this method, a rotor (or impeller) is inserted into the pipe through a hole in the pipe wall. As the fluid flows through the pipe, the rotor begins to rotate. Since the rotational speed of the rotor is proportional to the fluid flow rate, the flow rate can be determined by measuring the rotor's rotational speed.

In Line

In this method, as the fluid flows over a rotor (impeller) positioned in the flow path, the rotor begins to rotate. Since the rotational speed of the rotor is proportional to the fluid velocity, the flow rate can be determined by measuring the rotor's rotational speed.

Applications

Insertion Turbine Flow Meter

The primary application of this method is in measuring the flow rate of liquids in medium to large-sized pipes.

In-Line Turbine Flow Meter

One of the applications of these flow meters is the measurement of flow rates of low-viscosity liquids and clean gases.
