The Contrec 102A.2 is the standard wall-mount version of the 102A Flow Rate Totalizer, supplied with cable glands already fitted so it can be wired straight into the field on arrival without sourcing separate entry fittings. Like the rest of the range it draws its own operating power directly from a standard 4-20mA flowmeter loop, so it can be added onto an existing installation without running additional power wiring.
The IP67-rated watertight housing and internal electronics are shared across the whole 102A family, processing linear or square-law input and driving high/low rate alarms through optically isolated solid-state outputs, with an optional scaled pulse output for feeding a remote counter or PLC. Non-volatile memory protects programmed parameters and totals through a power interruption, and the whole unit is configured from its own tactile keypad without any separate programming tool.
