Application (for example): control of water hardness after a softener, for the protection of a reverse osmosis system.
With display of the measured hardness and possibility of calibration with a calibration solution (optional) or calibration with water on site.
The analyser is complete with:
4 programmable relay outputs: maximum value one, maximum value two (or minimum value and maximum value), command for a cooler, for a washing valve, pump, error, missing indicator, remote signaling.
1 output 0 (4) -20mA: analysis result (linear hardness) and operation.
2 programmable digital inputs: water meter, turbine water meter (Hall), flow meter, external start or stop commands.
CANBUS connection (optional).
SD card connection: data / results / error saving and transfer with date and time, software update.
A bad analysis can be repeated (just exceeded the maximum value, without giving an alarm signal)
Extensive function control program, relay drive, Leeds drive, accessory control.
Steps of an analysis cycle: opening an inlet solenoid valve – washing the measuring chamber for a settable time – checking the transparency of the water (zero point) – dosing the indicator by a peristaltic pump – result of the measured hardness (with display of the measured hardness) – final washing of the measuring chamber – the equipment stops waiting for the next analysis (timed, volumetric, manual or external signal start).
