Contrec 202Di Rate Totalizer is operated with a turbine, positive displacement, and paddlewheel flowmeters in applications such as irrigation systems and pipelines, and as a replacement for mechanical registers as well. Powered by long-life lithium batteries, therefore, Contrec 202D Field Mounting Rate Totalizer requires no external power. Alternatively, the Contrec 202D series rate totalizer can also be loop powered via an optional 4-20mA output or powered from a 9-28 Volts DC supply. Meanwhile, installation in hazardous areas a certified intrinsically safe version is available. The intrinsic safety approvals cover both the 4-20mA output and relay outputs, in addition to the input circuits.
The Contrec 202Di Rate Totalizer is housed in a rugged and also attractive IP67 (Nema 4X) rated polycarbonate enclosure and is completely watertight. In addition, 202D rate totalizer can also be mounted directly on the flowmeter, panel-mounted, or wall-mounted using a special universal bracket. A 2″ pipe mounting bracket is also available. In addition, K-factor, decimal point positions, filter constants, and time bases are fully user-programmable. Rate and Totals can also be displayed in different engineering units such as gallons per minute and barrels.
