The CFI 200 is a extremely rugged and versatile pulse input flow indicator. These indicators can be used for a wide variety of applications where accuracy and dependability are essential. These indicators accept pulse input. Two indicator modes are available Flow Rate and Total Flow. The Rate of Flow is shown in Line#1 and Total Flow in Line#2. In addition, all these instruments are field programmable and have nonvolatile backup memory that does not need cumbersome batteries. These instruments also have the capability to switch on relay(s) based on user settings. These outputs can be used for process set points and alarms. These instruments are compact and can be easily mounted in a panel. These instruments have RS485 or RS 232 option for communication to PC.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. These meters can also be used for Batch operation. Here the total volume of liquid to be measured can be programmed and the instrument can switch OFF a relay automatically after the required batch is complete
