Dwyer TFM液体涡轮流量变送器

Dwyer TFM液体涡轮流量变送器

The SERIES TFM-LP Liquid Flowmeters utilize a turbine wheel and electro-optical detection to convert flow rates into a linear 0 to 5 VDC and pulsed output signal for recording and data logging. A power adapter or mating cable assembly is required for operation
