  • After-sales service: Jiangsu Dongxiang Instrument provides delivery and provides after-sales service.

Product overview of plug-in vortex flowmeters <br /> According to the International Organization for Standardization ISO7145 (fluid flow measurement in a ring-shaped closed pipe-a speed measurement method at one point in the cross section), a vortex speed probe embedded in a piezoelectric crystal is used Insert it into a large-diameter industrial pipe, and convert the Carmen vortex frequency into a current or voltage pulse signal or a 4-20mADC current signal that is proportional to the flow.
Product features of plug-in vortex flowmeter

  • Can realize continuous flow disassembly sensor, can achieve amplifier and sensor separation (separation distance 15M;
  • Using anti-disturbance circuit and anti-vibration sensor head, so that the instrument has a certain resistance to environmental vibration;
  • Small pressure loss, wide measuring range, range degree reaches 1:25;
  • No moving parts, long-term stability, simple structure and easy installation and maintenance;
  • Measurable medium temperature reaches + 250 ℃;
