CircuitMeter’s JPulse-4™ is a uniquely designed pulse counter which is able to count pulses produced by any metering device that supports a standard dry contact output. The pulses are detected by the WebMeter36F™, which sends the pulse information to the CircuitMonitoring™ system in real-time. The JPulse-4™ is tightly integrated with the CircuitMonitoring™ system which will automatically convert the pulse signals from measuring water, gas, steam, and even generate an event counter.

Product Description

Monitoring Capabilities
Upon configuration, the CircuitMonitoring™ system will remotely reconfigure the RJ45 port on the WebMeter36F™ to switch to reading pulses (rather than current). This allows for total flexibility within the overall design of the CircuitMeter solution where the WebMeter36F™ is able to sense voltage, current and pulses.

The CircuitMonitoring™ system will generate reports and analytics for:

  • Water
  • Gas
  • Steam
  • Event Counter
  • Plus, any custom measurement(s) from readings

Technical Configuration
The JPulse detects industry standard dry contact pulses that utilizes three wires (common, loop, and pulse). The various levels of voltage are presented as outputs via the built in RJ45 jack to be connected to the WebMeter36F™ for pulse detection and interpretation of each pulse is calculated within the CircuitMonitoring™ system. The JPulse is enclosed in a metal box.
