Series TFP-LI Liquid Turbine Flow Meters are suitable for a wide variety of industrial,

commercial, and laboratory f low applications. These meters utilize a turbine wheel and
electro-optical detection to convert flow rates into a linear 0 to 5 VDC output signal for
recording and data logging. A 3-1/2 digit LCD informs the user of the actual flow rate. A
power adapter or mating cable assembly is required for operation.
