The Contrec 103D is a flow Rate Totalizer that requires no external power and design to operate with the turbine, positive displacement, and paddlewheel flowmeters in applications such as irrigation systems and pipelines, and as a replacement for mechanical registers.
The 103D Flow Rate Totalizer is DC powered type, operates from a 9-28 Volts DC supply and consumes no more than 4mA. This enables the Contrec 103D to power from AC mains adapters and eliminates the need to run mains voltages in the field. Lithium batteries provide totalizer and programming retention when the DC power supply is interrupted.
For installation in hazardous areas, a certified intrinsically safe version is available (Please see Contrec 202D), The Flow Rate Totalizer build with a rugged enclosure which is IP67 (NEMA 4X) polycarbonate. Hence, the enclosure is completely watertight.
