Proportional exacting metering pump
Exactus AstralPool membrane dosing pump in proportional model (controlled by mA Signal), for base and wall mounting.
The pump can be connected to a transmitter/indicator instrument or other device that supplies a signal of intensity modulated from 0 to 20 mA.
The impulse of the pump frequency index will be proportional to the signal of mA received: "At higher signal greater is the flow of the pump".
The pump can be adapted for reverse function, at higher signal lower flow rate.
The same model can be adapted for other mA (0-20mA, 4-20mA, 20-4mA).
