Flow Computers / Totalizers for Analog Signals These flow computers / totalizers are designed to work with differential pressure sensors or flow sensors that produce an analog signal proportional to the flow rate. They can be programmed to consider the analog signal linear to the flow rate or to extract a square root from it in order to calculate the flow rate. GFC240 flow computer / totalizer can accept a 4-20 mA signal linear to the flow rate or a 4-20 mA signal from a differential pressure sensor and extraxt a square root from it. If you need more space for wiring inside the enclosure, please order GFC240E. It has the same features but is mounted in one inch wider enclosure. All GFC100/200 series flow computers / totalizers will have a panel mount version in DIN 72x72 mm with IP65 (NEMA-4) protection. Coming soon .......... GFC300 is a high grade dual channel flow computer / totalizer that measures volume, compensated volume and mass of liquids and gases. GFC300 accepts almost any flow signal, measures temperature and pressure, has variety of high accuracy isolated outputs, RS485 MODBUS RTU port and many other features. Volume and mass of steam measurement will be added soon to GFC300 software. Saturated and superheated, in a very large temperature and pressure range, calculated with very high accuracy. GFC301 is a wall mount equivalent of GFC300
