Micro Power Flow Computers / Totalizers For Liquids When DC or AC power is not available our battery powered flow computers / totalizers offer accurate and reliable operation for many years on a single AA size replaceable battery. They have 7 digit flow rate, three 7 digit totals, 10 points calibration curves, data logging, a variety of outputs that can accuratelly control different pumps, provide batch capabilities, connect to SCADA systems or other devices. They can also power micro power sensors and still work reliably for years on a single AA size battery. For more power hungry sensors our micro power flow computers / totalizers have an option for powering with a C size replaceable battery. GFC101 has an universal input that can accept almost any pulse flow meter GFCP101 is the panel mount version in DIN 72x72 mm AH101 is a version of GFC101 with KFACTOR in pulses per liter NFC101 is a special design for irrigation, works on a single AA size battery and has an universal input that can accept almost any pulse flow meter with pulses down to one pulse every 5 minutes. It also has a programmable digital output for alarm or pulse and an isolated 4-20 mA output for flow rate. NFCP101 is the panel mount version. GFC101V has an isolated 0-5V (instead of 4-20 mA) analog output GFCP101V is a panel mount version of GFC101V GFC101VF has an isolated 0-5V fast analog output GFC104 micro power flow computer / totalizer has a simplified 2 level menu, separate volume units for rate and total and separate lock for each level of the menu GFC106 micro power flow computer / totalizer has a simplified menu, separate volume units for rate and total and no batch, limit, datalog or alarm options. KFACTOR unit is not fixed but in the total units programmed. SETP is in pulses per total unit. GFC106E is mounted in a wider enclosure NFC107 is a special design for irrigation, works on a single AA size battery, accepts reed switches and dry contacts and has no outputs. It is the lowest cost flow computer / totalizer of this series. NFCP107 is the panel mount version. If you need more space for wiring inside the enclosure, please order GFC10xE. They have the same features but are mounted in one inch wider enclosures.
