Example: Wireless Meter Reading
The system consists of one or more (up to 4) wireless pulse counters (SWSDPC) in an outdoor enclosure and a receiver I/O interface (SWRF-IOR-D).
Meter pulses are collected by the wireless pulse counter and transmitted to
the receiver module. The I/O interface re-generates the meter pulses at its
digital outputs. The maximum frequency (f = 1/Pulse_Period) and Pulse
Duration of the re-generated pulse can be configured using NQ software.
Digital outputs are wired to a controller or data gateway for remote access of
consumption and demand. The Status output indicates low-battery or
communication timeout (>45 minutes) and can be used as an alarm.
All meters with a “dry contact” pulse output (<90 pulses/sec.) are supported.
The SWS-DPC can be battery powered or powered by a 9VDC power supply.
When powered by 9VDC, the SWS-DPC will also function as a repeater.
