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.
Modbus, Modbus TCP
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
