Turbine Flow Meter

Turbine Flow Meter makes use of a light weight, precision balanced rotor to accurately measure flow rate of clean liquids. It works by rotating the rotor due to the effect of the flow of liquid, creating a steady output signal for measuring flow rate.

This meter may also function as a turbine flow transmitter with the inclusion of magnetic pickup and electronic display. The microprocessor driven system translates the movement of the rotor into reliable flow measurements.

The Turbine Flow Meter operates in tough environments with capability of handling pressure and temperature up to 180°C based on specific model and materials.

Due to its strong construction, it has decent tolerance for different process fluids such that it is effective in applications dealing with water, chemical solutions and other clean liquids.

Fluid Entry & Alignment 

As a clean medium passes through the industrial turbine flow meter, it enters the meter body. A fluid guide stabilizes the medium, directing it smoothly toward an aerodynamically shaped rotor designed to minimize pressure drop.

Linear to Rotational Conversion

The kinetic energy of the moving fluid pushes the blades, forcing the rotor to spin. This high-precision rotor rolls on a robust tungsten carbide shaft and bush bearing. The angular velocity (rotational speed) of the turbine meter remains directly proportional to the linear velocity of the passing liquid or gas.

Non-Intrusive Pulse Generation

An externally mounted, detachable magnetic pickup coil acts as the core turbine flow meter sensor without piercing the pressure boundary. As the magnetic blades pass beneath this sensor, they interrupt the localized magnetic field, generating a discrete electrical frequency signal.

Signal Conversion & Processing

The digital turbine flow meter with a signal output converter transforms these raw electrical pulses. The integrated electronics module processes the frequency into precise engineering metrics (e.g., liters, m³/hr).

Smart Volumetric Output

Utilizing smart turbine flow meter measurement technology, the system delivers real-time digital readouts. This ensures highly accurate, long-term turbine flow measurement, transmitting continuous 4–20mA or RS485 Modbus signals directly to your control system for flawless data logging.
