The NFC-101E is a micro-power battery powered flow computer totalizer with an outstanding combination of excellent features, extremely long battery life, universal input, up to 100 Hz. It accepts open drain/collector npn, reed switch, dry contact, waves and logical signals. NFC-101E has an open drain 100V/100mA output that can be programmed to work as a rate alarm: high or low, with +/- 1 % hysteresis, or scaleable pulse output.
The NFC-101E software implements a special design for registering flow meters which produce very low frequency pulses. Special proprietary algorithms allow the NFC-101E to accept low frequency pulses for example, one pulse every 5 minutes and still have a stable reading and analog output. At the same time the flow rate reading can be cleared instantly by an external “no flow” switch input. NFC-101E is the perfect solution for flow measurement and control applications that require high accuracy and reliability, small size, industrial grade performance and low maintenance.
