Description
Description
The DP-F31 ratemeter/totalizeraccepts 3 to 30 Vdc pulses,dry-contact closure, voltage, ormilliamp inputs, and provides2-stage SPDT relay outputs forbatch control. The display is fullyscalable for engineering units andmay be toggled between batch total,rate, and grand total. Thelinearization option allows the userto select up to 16 different K factorsover the input range for accurateindication of non-linear signals.
Other features include 12 to 24 Vdcoutput for powering up flowmeters;pulsed (0.1 to 9.9 s) or maintainedoutputs; input filtering for dry-contactclosure (such as reed relays);local/remote reset; excitation foropen-collector or mechanicalcontacts; user-programmableauto-reset of batch total (repeatcycles, 10 Hz max); security lockoutto prevent unauthorized changes;factored pulse output; and analogoutput for rate or total (analog outputnot available with square root-SQRT option).
The DP-F30 series indicates rateto 5½-digits and total to 8-digits, withprogram and count data stored forup to 10 years if power is lost.
