FI 592 Flow Indicator & Totalizers are extremely versatile indicators that can be used with a variety of Analog output flow sensors. These indicators offer extreme reliability and low cost for flow measurement. FI 592 Flow indicator & Totalizers can be used with Current (or) Voltage output sensors. Micro controller based electronics ensures accurate readings for both rate of flow indication and total flow indication. A number of programmable features including Inline calibration are standard. All the parameters are saved in a non volatile EEPROM memory which doesn't needs any external battery. There is a advanced power fail feature by which even if there is any power failure the Total Flow reading is automatically saved to memory and resumes with the same value after Power On. Programmable Flow Rate High & Low Range Selection for Various Flow Sensors & Transmitters. Selectable Units & Resolution. Selectable Linear / Square root Conversion for Analog Input(4 - 20mA).
