Trimec-Europe has brought out a flow-rate totaliser designed for computing and displaying flow rates and totals from flowmeters with pulse, sine wave or frequency outputs. The RT20 Rate Totaliser can be battery or externally powered and features a six-digit large LCD total, eight-digit cumulative totaliser and five-digit rate display.The instrument displays resettable (batch) total, cumulative total and instantaneous flow rate in engineering units as programmed by the user. A robust IP66/67-NEMA 4X aluminium field and panel-mountable housing make the unit suitable for rugged applications. It also features a backlit panel enabling distance viewing at night when de-powered. The RT20 is designed for simple PIN-protected flow-chart programming, with English-language prompts guiding users through the programming routine, which reduces the need to refer to the instruction manual.
Other features include scaleable universal pulse or frequency inputs, scaled pulse output, long battery life, non-volatile memory and reverse-polarity protection. Additional options to suit specific applications include a heavy-duty facia protector shield, a relay board with SPDT outputs and flowmeter and pipe-mount kits. Other units available include battery totalisers, automatic batch controllers and a rate totaliser with 4-20mA, alarm and scaleable outputs, dual-flow inputs and linearisation.
