In operation the microprocessor transmitter converts the measured
process flow into a 4-20mA output with HART protocol. The signal
originates when the float magnet inside the metering tube passes a
magnetic sensor mounted on the transmitter. Flow rate information may
be viewed locally at the meter scale or displayed remotely (along with other
flow data) as a function of external support systems through analog/pulse
outputs or multiple digital communications.
In addition to transmitter features, this unit can also be ordered with
optional alarms and pulse output provided by open collector switches. One
or two alarms may be programmed prior to shipment of the unit or at the
customer site with a hand-held communicator.
