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.
