Dosing pump eOne PLUS 20/7

The eOne Plus microprocessor dosing pump is suitable for proportional and control applications: pH, Rx, Cl, ppm monitoring. The pump operates at high dosing frequency (up to 300 impulses/min) and is equipped with backlit graphic display for correct setting of various programming parameters. The functions performed by the pump are: Proportional mode Functions.

Multifunction microprocessor dosing pump, suitable for applications which require proportional dosing. The pump operates at a high dosing frequency (up to 300 impulses/min) and is equipped with backlit graphic display for correct setting of the various programming parameters. The functions performed by the pump are as follows:  •  Calibration procedure of the actual impulse injection rate delivered to a specified need  •  Manual flow rate regulation 0..100 %, 0..300 impulses/min  •  Proportional mode 1 x n (pulse multiplier), at each signal from the pulse supply emitting meter corresponds “n” injections of the pump, during the injections any following pulses neglected  •  Proportional mode 1 x n(M) (pulse multiplier with memory), at each signal from the pulse supply emitting meter corresponds “n” injections of the pump, during the injections the following pulses from the meter are memorized and the pump modifies “n” (injections to be delivered) in proportional to the pulses received from the meter during the dosing  •  1:n function (pulse divider), at each signal from the pulse supply emitting meter the pump delivers a dosing product injection  •  ml x I, at each signal from the pulse supply emitting meter the pump delivers a specific amount of the dosing product in “ml” (millilitres), corresponding to the value set during the programming phase  •  l x I function, at each signal from the pulse supply emitting meter the pump delivers a specific amount of dosing product in “l” (litres), corresponding to the value set during the programming phase  •  ml x m3 function, at each signal from the pulse supply emitting meter which indicates the transition of l m3 of fluid, the pump delivers a specific amount of dosing products in “ml” (millilitres), corresponding to the value set during the programming phase  •  ppm function, the dosing pump makes the necessary calculations and doses the exact amount of ppm (parts per million) set during the programming phase  •  mA function, the pump doses in a proportionally to the current signal (usually 4..20mA) riceived by a flow meter or another connected device  •  timer/ programmer  function  •  UNDERLOAD – Suction alarm  •  OVERLOAD – Discharge alarm  •  Flow sensor alarm – the activation of this alarm indicates an injection failure.  A Flow Sensor, located on the discharge side of the pump head, has not detected a predetermined number of injections despite the activation of the electromagnet  •  Alarm for too many pulses from the supply pulse emitting meter – this is activated when the set parameters, in the functions “1 xn(M)” and “ppm”, have been exceeded from the supply pulse emitting meter. The user must restore the correct setting of the dosing pump  •  Level control setting (supplied without probe)  •  Relay output for signalling the alarm status. Controller mode Functions. The dosing pump activates the measuring input pH, ORP, Cl, range  •  Measere Range: 0.00 ÷ 14.00 “pH”, -1000 ÷ +1400 mV “Redox”, 0÷2, 0÷20, 0÷200 ppm (Cl), 0÷2, 0÷20, 0÷200 ppm (Ion-selective sensor of for a specific chemicals)  •  Temperature control definition: automatic (connection to PT100 sensor) or manual (default 25°C) •  Setting for the value of set point  •  Type of intervention (direct or inverse)  •  Hysteresis setting  •  ON/OFF or proportional activation mode  •  Delay time of the pump activation  •  MAX alarm, for maximum measure  •  MIN alarm, for minimum measure  •  Over alarm, indicates an overdose situation. This is activated when the defined set point value is not reached in a predetermined time  •  Level control setting (supplied without probe)  • Relay output for signalled alarm status.
