Click here if you want to know more about flow meters.
FP1400 Series flowmeters support various functions
including; two independently programmable flow
totalizers, user programmable low, high or range flow
and temperature alarm, two sets of user
programmable optically isolated outputs, self
diagnostic alarm, and flow pulse output. The flow rate
can be displayed in 29 different volumetric or mass
flow engineering units. Flowmeter parameters and
functions can be programmed locally via optional key
pad and LCD or remotely via the RS232/RS485
interface. Local 2 x 16 LCD readout with adjustable
backlight provides flow rate, temperature, total volume
reading in currently selected engineering units,
diagnostic events indication and feature a password
protected access to the process parameters to ensure
against tampering or resetting.
Liquid flowing through the unit causes the paddlewheel
to spin. As the magnets embedded in the paddle spin
past the sensor, electrical pulses are produced in
which frequency is proportional to the flow rate. The
number of pulses per desired time interval and the Kfactor
(number of pulses/gal) make it is possible to
calculate the flow rate and volume passing through the
unit. On board CPU and signal conditioner circuitry
perform accurate flow and total computation, digital
communication and analog 0 to 5 Vdc or 4 to 20 mA
output signals. Non-volatile memory stores all
hardware specific and user programmable variables,
including flow linearization table.
