Spinwave Systems, Inc.

Wireless Pulse Counter, SWS-DPC

Type:  Monitoring Hardware
Description:  Spinwave Systems' Pulse Counters are used to wirelessly transmit electric/water/gas meter values (accumulated pulses and pulses per time) and make them available as Modbus or other industry standard protocol variables using Spinwave's BMS Protocol Interface or as digital outputs (pulse replication) using a BMS I/O Interface. The Pulse Counter consists of a high-power radio and a signal conditioning module. The radio is connected through a standard CAT5 cable to the signal conditioning module, providing data and power to the radio. Up to 31 pulse counters can be wirelessly connected to a single BMS protocol gateway for remote metering applications. Wireless Repeaters/Routers are available to cover large indoor or outdoor areas.
Connectivity:  Modbus, Modbus TCP
Features:  Can be battery or line-powered-(6 D-cell batteries will last up to 8 years); suitable for both indoor and outdoor applications (when mounted in weather-proof enclosures); wireless sensor network (based on IEEE 802.15.4) outsmarts changing RF interferences with self-adapting frequency agility (patent pending); self-forming and self-healing wireless mesh network for robust operation; wide range of mounting options; sensor parameters can be easily changed wirelessly
Specifications:  Radio Characteristics: 2.4GHz, IEEE 802.15.4, Receiver Sensitivity -95dBm, Receiver Adjacent Channel Rejection +/-5MHz, 46/39 dB, Receiver Alternate Channel Rejection +/-10MHz, 58/55 dB; Open field Range: Receiver/Router: up to 3500 ft. (1 km), Receiver/Sensor: up to 700 ft. (230 m) In-building Range per hop (Sensor to Repeater or Repeater to Repeater) 120 ft. (40 m) in typical commercial office building; transmission interval: 21 seconds, user configurable; Power: 3.5VDC to 6VDC, radio will automatically assume functionality when powered between 5.5VDC to 6VDC; Interfaces: 1 pulse input for dry contact, 90Hz max, DC power connector.
