Analogue Input Rate Totaliser
The Contrec 202A loop powered Field Mounting Rate Totaliser is designed to operate with any flowmeter which produces a 4-20mA output, including differential pressure devices, magnetic or vortex flowmeters. The 202A is powered entirely from the 4-20mA current loop and has a maximum of 2.5 volts drop across the input.
The Rate Totaliser is fully programmable with linear or square law input relationships, programmable span, cutoffs and conversion factors. A non-volatile memory stores all set up parameters and totals without the need for internal batteries or external power.
High and low alarms are standard via optically isolated solid state relay outputs. Alternatively, the high alarm output can be programmed to provide a scaled pulse output proportional to the total.
The 202A Rate Totaliser is housed in a rugged, yet attractive, IP67 (Nema 4X) polycarbonate enclosure which is completely watertight.
A wall mounting bracket is supplied as standard, while a 2″ pipe mounting bracket is available as an option. Alternatively, the Model 202A can be supplied as a panel mount instrument.
The Model 202A is certified as intrinsically safe to European CENELEC standards, and CSA standards for both the USA and Canada.
