Overview
CFI100 series flow meters are extremely versatile flow indicators that can be used with a variety of pulse output flow sensors. These indicators offer extreme reliability and low cost for flow measurement. CFI100 series flow indicators can be used with mV pulse output sensors, open collector pulse output sensors as well as TTL pulse output sensors. Microcontroller based electronics ensures accurate readings for both rate of flow indication and total flow indication. A number of programmable features including In-line 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. Advanced models can offer relay outputs for signals exceeding rate of flow or total flow set points. Programmable pulse output models are also available in addition to the industry standard 4-20mA output. These instruments can be connected to a PC via RS485/ RS 232 using MODBUS interface.
