Mini Liquid Turbine Flow Meter, Electronic Digital Turbine Flow Temperature Sensor

The FXN flow temperature sensor features a simple structure, high accuracy, and ease of installation, maintenance, and use. It can monitor the flow and temperature of liquids in pipelines in real-time, providing 4-20mA signal or pulse signal for flow, alarm switch output for temperature, and 4-20mA signal and alarm switch output for temperature. It also utilizes an OLED display to show fluid flow and temperature in real-time, achieving integrated monitoring of temperature and flow in pipelines. It is widely used in industries such as petrochemicals, power, metallurgy, steel mills, papermaking, food processing, water treatment, and battery manufacturing.

Operating Principle:

The principle diagram of the turbine flow meter is shown as follows. A turbine is installed at the center of the pipe, supported by bearings at both ends. As the fluid flows through the pipe, it impacts the turbine blades, causing the turbine to rotate at a speed proportional to the fluid velocity. The fluid flow drives the turbine rotation, cutting through the magnetic flux lines generated by the magnetic steel within the casing, resulting in a change in magnetic flux. The sensing line sends the detected magnetic flux cycle change signal to a pre-amplifier for amplification, producing a pulse signal proportional to the flow velocity. The flow rate is then calculated through circuit operations.
