COMET F2
INDUCTIVE FLOWMETER
COMET F2 - CONTROL UNIT
It is at all points certified unit of inductive flowmeters CPMET F2, with wide range of additional functions, that give to
user comfortable service.
Important properties:
- High precision of flow measuring in both directions.
- Easy option of mode and parameters (by means of 5 buttons or from PC).
- Backup clock of real time.
- Possibility of periodical clearing of sensor’s electrodes.
- Possibility of saving 1.000 data samples.
- Liquid batching.
- Option of dead zone and damping of impression.
- Two independent multifunctional outputs.
- Frequency output, analogue output (up to 800Ω).
- Calibration methods adaptable to test rooms.
In case of set meter (metrology seal), the User cannot change either the calibration constants or cumulated values.
Detail information you will find in manuals: COMET F2 – Installation Manual, COMET F2 – Reference Manual.
