The Contrec 103D.2 is the standard wall-mount version of the 103D Input Flow Totalizer, supplied with cable glands already fitted for field wiring straight out of the box. It runs on external 9-28V DC power and works with turbine, positive displacement, and paddlewheel flowmeters, displaying live rate and cumulative total on its own weatherproof LCD.
Four opto-isolated alarm outputs give it more alarm points than the battery-only 102-series units, useful where high and low flow limits both need independent signaling out to a PLC or annunciator. The same IP67 watertight enclosure and internal electronics carry over from the rest of the 103D range, with two years of battery backup keeping programmed settings and totals safe through a power interruption.
