1. Product

The flow sensor flow profile like the venturi tube shaped wire (pic 2), install one group sprial guide buffle in the side of entrance, while the fluid enter the flow sensor, the guide buffle will press the fluid generate strong swirl flow, when the fluid enter expansion section, the swirl flow will generate second time rotating under the effect of counterflow, and shape the swirl precession phenomenon of gyroscopic shape. The precession frequency in proportion to flow volume, it will not influenced by fluid physical property and density, when get the fluid second time precession, the testing element will get better linearity in the wide flow range. The signal will be magnified via front amplifer, filting and transform into the pulse signal in proportion to flow rate, then send to the micro processor undertake totalizering process with the temperature, pressure testing signal, finally it will display the measured result on the LCD displayer ( instantaneous flow total flow and temperature, pressure data).

2. Features

    1. No mechanical moving parts, not easy to corrode, stable and reliable, long life, long-term operation does not require special maintenance;

    2. Using 16-bit computer chip, high integration, small size, good performance, and strong functions of the whole machine;

    3. The intelligent flowmeter integrates flow probe, microprocessor, pressure and temperature sensor, and adopts a built-in combination to make the structure more compact. It can directly measure the flow, pressure and temperature of the fluid, and automatically track the compensation and compression factor in real time. Amend

    4. Adopting dual-probe detection technology, new sensor processing technology, and reasonable installation methods to greatly improve the signal strength, so that the sensor can accurately detect the signal, and suppress the interference caused by pipeline vibration;

    5. Adopting domestic leading intelligent anti-seismic technology, effectively suppressing interference signals caused by vibration and pressure fluctuations;

    6. Adopting Chinese character dot matrix display, with many display digits, intuitive and convenient reading, which can directly display the volume flow in working state, volume flow in standard state, total volume, and parameters such as medium pressure and temperature;

    7. The converter can output frequency pulses, 4-20mA analog signals, and has an RS485 interface, which can be directly networked with a computer, and the transmission distance can reach 1.2km;

    8. Multi-physical parameter alarm output, users can choose one of them;

    9. Pressure and temperature signals are sensor input methods, which are highly interchangeable;

    10. The whole machine has low power consumption and can be powered by the built-in battery or an external power supply.
