DescriptionFeaturing 8 digits of bright, 14 mm (0.55"), alphanumeric display, the DPF-310 Series can accept up to 20,000 pulses per second of digital count. The analog input version accepts 4 to 20 mA signal and it uses a highly linear integrator (V to F converter) to generate 0 to 10 kHz digital pulses. The standard unit has 2 separate, 8-digit, floating decimal, “K” factors to convert the inputs to meaningful total and rate data. An optional 16-point K-factor can linearize flow from non-linear meter outputs. The user, with the push of a button, can toggle back and forth to view the total of the batch, the rate of flow or the grand total of flow.
