Superior design meets serious workhouse in the Sentinel LCT4 Liquid Flow Meter. Fully enclosed in protective explosion-proof housings, our transducers have less of a buffer between them and the liquid flow—creating reduced transit time and better accuracy. Ultrasonic has comparable measurement to mechanical meters, but with no moving parts—saving you money on lower installation, maintenance and energy costs. Plus, the additional diagnostics give you a clearer picture of exactly what is happening inside the pipe.
