Counters/Flow : SPP-94
SPP-94 are the flow meters designed to work in tandem with the pulse flow transducers with current input of 0-20 mA or 4-20 mA. Wide range of total flow (up to 16 significant digits) enables flow volume control for a long time. Build in a batcher function makes possible application of SPP-94 in a wide range of industry branches (food production, pharmacy, paint and varnish).
