Contrec 102A
Brand: Contrec LtdThe 102A is powered entirely from the 4-20mA loop.
The Rate Totaliser is fully programmable with linear or square law input relationships, programmable span, cut-offs and conversion factors.
A non-volatile memory stores all set-up parameters and total in the event of a power failure.
Rate of Flow, Resettable Total and Accumulated Total are all programmable in engineering units.
The 102A Field Mounting Rate Totaliser is a high accuracy Rate Totaliser designed to operate with analogue output flow meters. Having an IP67 weatherproof case, tactile keyboard and various mounting options, makes it a very versatile unit.
The Field Mounting Rate Totaliser is fully programmable with linear or square law input relationships, programmable span, cut offs and conversion factors.
A non-volatile memory stores all set-up parameters and totals in the event of a power failure.
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 102A Field Mounting 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.
