Signal Inputs

Flowmeter Inputs

• • • Pulse type inputs:
      Reed-switch, open collector, NAMUR, NPN/PNP pulse, Sine wave (coil), active pulse signal.

Signal Outputs

Pulse outputs

• • • Function: Scaled pulse output according to linearized accumulated total (e.g. a pulse every 3.25 gallons).
      Max. frequency: 500Hz.
      Adjustable pulse length from 0.001 sec. to 9.999 seconds.
    • Type: Up to three passive NPN transistors, active PNP transistors or isolated electro-mechanical relays.

Alarm outputs

• • • Function: Configurable alarm outputs for low, high or both combined flow rate alarms.
    • Type: Up to three passive NPN transistors, active PNP transistors or isolated electro-mechanical relays.

Analog outputs

• • • Function: Re-transmitting the linearized flow rate – the output can be scaled to any range (e.g. 200 L/min to 1200 L/min).
    • Type: One passive isolated, floating or loop powered 4 – 20mA output or one active (0)4 – 20mA or 0 – 10V DC output.
