Автономный регистратор объемного расхода
  • Continuous measurement of fluid flow, calculation of the total volume.
  • Accumulation of information about the measured volume during the hour, day, month in the nonvolatile memory.
  • Built-in real time clock with autonomous power source.
  • Works in together with a variable differential pressure flowmeters with a standard diaphragm.
  • Setting max and min consumption, Reynolds number correction coefficients for different consumption values.
  • Setting water temperature according season.
  • Possibility to calibrate differential pressure to increase accuracy of measuring. 
  • Power supply from the built-in 3.6 V lithium battery with a capacity of 7.2 A•h (autonomous operation for at least 1 year).
  • Flowmeter is made in housing of “Sapphire-22DD” measuring converter of pressure difference.
  • Reading data from the flowmeter is performed via the remote control.
