Scaled Output
• Scaled output is a switch closure output defined as: red wire = positive, black wire = negative.
• Scaled digital output from the register has a default resolution of 1/10th of the register test circle (resolution may vary in
some cases).
• The movement of the meter magnet is converted to a square wave signal that is available as a scaled output through a
solid-state relay.
• Scaled output is a solid-state relay to provide isolation from the 4-20 mA output.
• The nominal pulse output width is programmable from 30…100 msec.
• The resolution of the output is defined in the registration section.
• This digital pulse output is compatible with most totalizers and batch controllers.
Unscaled Output
• Unscaled output is a switch closure output defined as: green wire = positive, black wire = negative
• The movement of the meter magnet is converted to a square wave signal that is available as an unscaled output through a
solid-state relay.
• Unscaled output is a solid state relay to provide isolation from the 4-20 mA output.
• The resolution of the output is defined in the registration section.
• The unscaled output will only be active when the device is powered by the 4-20 mA output.
• This digital pulse output is compatible with most totalizers and batch controllers.
Analog Output
• The input pulses generated within the transmitter assembly are converted to a standard 4-20 mA control signal.
• This signal is proportional to the flow of fluid passing through the flow meter.
• Power for the device can be obtained from a 9…50V DC control loop.
• The default 20mA setting of the signal is defined in the registration section.
