Autonomous fluid flowmeter AROR

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.
