Instrument Features<\/strong><\/p>\n

    \n
  1. 1.The sensor employs adaptive variable frequency excitation technology, resulting in fast processing speed, high accuracy, and lower power consumption.<\/li>\n
  2. 2.It can simultaneously measure the instantaneous flow rate, temperature, and pressure parameters of fluid in a pipeline.<\/li>\n
  3. 3.It employs multiple ARM Cortex-M4 32-bit processors and a 24-bit ADC data acquisition system, resulting in faster operation.<\/li>\n
  4. 4.It features fully digital signal processing, strong anti-interference capability, reliable measurement, high accuracy, and a wide flow measurement range.<\/li>\n
  5. 5.Ultra-low EMI power supply, applicable to a wide range of power supply voltage variations, and excellent EMI immunity.<\/li>\n
  6. 6.The circuit employs rigid-flex PCB and surface mount technology (SMT) for high reliability.<\/li>\n
  7. 7.The instrument has self-diagnostic functions such as empty pipe detection, excitation circuit fault detection, and flow alarm.<\/li>\n<\/ol>\n
