Contrec 103D Flow Rate Totalizer is a DC powered Rate Totaliser and is designed to operate with Turbine, Positive Displacement and Paddlewheel Flowmeters in applications such as irrigation systems and pipelines, and as a replacement for mechanical registers.
The 103D is a high accuracy Rate Totaliser designed to operate with digital output flowmeters. Having an IP67 weatherproof case, tactile keyboard and various mounting options, makes it a very versatile unit.

Field Mounting Rate Totalizer
The 103D is powered from a 9-28 Volts DC supply. For installation in hazardous areas, a certified intrinsically safe version is available (please see Model 202D). The DC powered version will operate from an external power source between 9 and 28 Volts and draws no more than 4mA. This enables the 103D to be powered from AC mains adaptors and eliminates the need to run mains voltages in the field.
Lithium batteries provide totalizer and programming retention if the DC power supply is interrupted. The 103D Rate Totaliser is housed in a rugged, yet attractive, IP67 (Nema 4X) polycarbonate enclosure which is completely watertight. A wall mounting bracket (no gland holes) is supplied as standard, while panel and pipe mounting brackets are available as options.
