The 202D Field Mounting Rate Totaliser requires no external power 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 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.
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.
K-factor, decimal point positions, filter constants and time base are fully user programmable. Rate and Totals can also be displayed in different engineering units such as gallons per minute and barrels.
