  • With a sophisticated low-power LCD display, the local display shows instantaneous flow, cumulative flow, frequency, pressure, temperature, density, current, percentage etc .
  • Probe used four piezoelectric ceramic technologies to effectively eliminate the influence of external vibration on the measurement
  • No moving parts, no wear, no mechanical maintenance and long service life
  • The probe and signal converter are universally interchangeable
  • Split type signal converter can be used, the cable can be up to 10 meters long.
  • Output 4-20mA current signal / pulse signal, or Modbus RS485 signal
  • Two types of intrinsic safety explosion-proof: Exia II CT6Ga; flameproof: Exd II CT6Gb
  • With HART–Protocol communication protocol, Modbus RS485 interface.
  • Widely used in Paper, sugar, various beverages
  • Water supply and drainage, environmental protection,
  • Water conservancy engineering, steel, petroleum, mining,
  • Pharmaceutical, heating, water supply,
  • Hot steam, saturated steam, compressed air.
