Contrec's Field Mounted Rate Totaliser Model 202D requires no external power and is designed to operate with turbine, positive displacement and paddle wheel flowmeters in applications such as irrigation systems and pipelines, and as a replacement for mechanical registers.
Battery, Loop or DC powered
The standard 202D is powered by long-life lithium batteries. Alternatively, the 202D can be loop powered via an optional 4-20mA output, or powered from a 9-28 Volts DC supply. For 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.
Watertight field mounting enclosure
The 202D Rate Totaliser is housed in a rugged yet attractive IP67 (Nema 4X) rated polycarbonate enclosure which is completely watertight. This enables the instrument to be mounted directly on the flowmeter, panel mounted or wall mounted using a special universal bracket. A 2″ pipe mounting bracket is also available.
