• 

 PRC-1003 type intelligent rotary vortex flowmeter is the ideal instrument in petroleum, chemical, electricity, metallurgy, and other industries for gas measurement.
1.1 Features
  Without movable parts, high stability and reliability, long service life;
  High integration level, small volume, good performance, complete functions;
  Intelligent flowmeter integrated flow probe, microprocessor, pressure sensor and temperature sensor; it can measure flow, pressure and temperature of liquids directly;
  Dual detection technology can effectively improve the detection signal strength and inhibit the interference caused by the vibration of the pipeline;
  The domestic leading intelligent earthquake proofing technique effectively inhibits the interference signal caused by vibration and pressure fluctuation; 
  The Chinese character dot matrix display screen can display volume flow in working state, volume flow, total volume, medium pressure and temperature in standard state, 
  Adopts EEPROM, parameter setting is more convenient;
Low power consumption.
1.2 Main uses
