Available as battery or externally powered, the RT20 Rate Totaliser features a large six-digit LCD total, eight-digit cumulative and five-digit rate display for easy reference. All these are displayed in engineering units as programmed by the user.

There is a keypad with LCD backlighting which, when DC powered, enables easy flow chart touch key data input while a simple PIN-protected flow chart programming with English prompts guides the user through the programming routine, significantly reducing the need to refer to the instruction manual.

RT20 is housed in a robust IP66/67-rated aluminium field and panel-mountable housing so it is suitable for more rugged applications. However, for even more challenging situations, heavy facia protector shield, relay board with SPDT outputs and flowmeter and pipe mount kit options are available. Other features and benefits include, scaleable universal pulse or frequency inputs, scaled pulse output, long battery life, non-volatile memory and reverse polarity protection.
