FLOMEC® LCD display RT14 / RT12 is a fully programmable self-powered flowrate totalizer specifically designed for computing and displaying flowrates and totals from flowmeters with pulse, sine wave or frequency outputs.
The instrument displays resettable (batch) total, cumulative total and instantaneous flowrate in engineering units as programmed by the user.
RT12 is Intrinsically Safe
