Features of precessional vortex gas flow meter
- No mechanical moving parts, not easy to corrode, stable and reliable, long service life, long-term operation without special maintenance;
- 16-bit computer chip, high integration, small size, good performance, powerful function;
- The intelligent flow meter integrates flow sensor, microprocessor, pressure and temperature sensor into one, and adopts a built-in combination to make the structure more compact, which can directly measure the flow, pressure and temperature of the liquid, and automatically monitor compensation in real time. . and compression ratio correction;
- Dual probe detection technology, new sensor processing technology and reasonable installation method are adopted to greatly improve the signal power, so that the sensor can accurately detect the signal and suppress interference caused by pipeline vibration.
- Adopts matrix display, which can directly display the volume flow in working state, volume flow in standard state, total volume, average pressure, temperature and other parameters.
- The converter can output frequency pulse, 4~20mA analog signal, has RS485 interface, can be directly connected to the computer network, transmission distance is up to 1.2 km;
