Dwyer TFM-LI Series Liquid Turbine Flow Meter

Wiratama Mitra Abadi 01 05.23 flow measurement,

Dwyer TFM-LI Series Liquid Turbine Flow Meter with electrical transmission output for remote indication of liquid flow rate. Dwyer turbine flow transmitters are suitable for a wide variety of industrial, commercial, and laboratory flow applications. A power adapter or mating cable assembly is required for operation.

LI Liquid Turbine Flow Meters are suitable for a wide variety of industrial, commercial, and laboratory flow 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.
