Low Power Flow Computers For Liquids When DC or AC power is available our low power flow computers / totalizers can work with more types of flow meters, provide more power to the sensor, measure faster pulse signals up to 10 kHz and communicate with a master device over a MODBUS RTU or other network. GFC110 works with most flow sensors and provides 5VDC for the sensor. It is especially suitable for direct connection to 3 wire opto coupler flow meters. It limits the current to the flow sensor opto coupler. GFC110P flow computer / totalizer does not limit the current to the flow sensor GFC110A-B flow computer accepts a biderectional flow sensor and displays flow rate A, flow rate B and total A-B. It has isolated pulse output and isolated analog output. No batch, no limit, no data log. GFC110-AC works with 25 VAC power AH110 is a version of GFC110 with KFACTOR in pulses per liter AH110P flow computer / totalizer does not limit the current to the flow sensor GFC110D is special design for flow meters that provide extremelly low frequency pulses. It can work with down to 1 pulse every 5 minutes and still show stable flow rate. GFC111 works with almost any flow sensors and provides 10VDC/20 mA to the sensor. It can work with 2 wire flow meters, NAMUR, proximity switches and others. GFCP111 is a panel mount version of GFC111 AH111 is a version of GFC111 with KFACTOR in pulses per liter AHP111 is a panel mount version of AH111 GFC111-MB flow computer / totalizer has in addition a fully compliant programmable RS485 MODBUS RTU port and 30 point calibration table / curve for linearization of the flow meter reading. GFCP111-MB is a panel mount version of GFC111-MB AH111-MB is a version of GFC111-MB with KFACTOR in pulses per cubic meter. AHP111-MB is a panel mount version of AH111-MB GFC113 has a very fast isolated 0-5V output and is especially useful for laboratory tests of flow dynamics. GFC114 has a simplified 2 level menu, separate volume units for rate and total ans separate lock for each level of the menu AH114 is a version of GFC114 with KFACTOR in pulses per cubic meter GFC116 low 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. If you need more space for wiring inside the enclosure, please order GFC11xE. They have the same features but are mounted in one inch wider enclosures.
