Specifically designed for computing and displaying flowrates and totals from flowmeters with pulse, sine-wave or frequency outputs, the RT20 Rate Totalizer (photo) can be battery or externally powered and features a large six-digit LCD total, eight-digit cumulative totalizer and five-digit rate display. The instrument displays resettable (batch) total, cumulative total and instantaneous flowrate in engineering units as programmed by the user. A robust IP66/67-NEMA 4X aluminum field and panel mountable housing makes the unit suitable for the most rugged applications. It also features a backlit panel enabling distance viewing at night when de-powered. The RT20 is designed for simple PIN protected flowchart programming with English language prompts guiding users through the programming routine thereby reducing the need to refer to the instruction manual. — Trimec (Europe) Ltd, Haywards Heath, West Sussex, U.K.
