Configurable wireless sensor transmitter ARF8230 series

low-powerprogrammablepulse

Product overview
The PULSE sensor reads and analyses consumption data from water, electricity or heat meters and counts equipment cycles to support maintenance planning. It is a wireless pulse interface designed for straightforward connection to meters or any device with a pulse output.

Highlights of the IoT sensor

• 2 configurable pulse inputs (dry contact, REED, S0, open collector)
• Over 15 years battery autonomy depending on version and configuration
• Fraud and leak detection
• Flow monitoring for meters
• Periodic and/or event-triggered data transmission
• Data logging for optimized autonomy
• Local (USB-C) and remote configuration
• Compatible with KARE+
• Available: LoRaWAN (EU863-870, US902-928, AU915-928, AS923-1), Sigfox (RC1/RC2/RC4), NB-IoT / LTE-M
• 6-wire version and ATEX option available

Features of the PULSE IoT sensor

• Connects two 3-wire meters or one 5-wire meter (6-wire variant)
• Periodic transmission of meter indexes or equipment cycles, with optional value logging
• Alarms and event-triggered messages for flow thresholds (high/low) and leak detection
• Configurable frame redundancy (repeats per frame)
• Fraud input per channel to detect status changes
• Local configuration via USB-C and remote configuration via network (periodicity, transmission modes, alarm thresholds)
• Product error, configuration error and low battery alerts
• Pulse detection test at start-up (LoRaWAN); programmable acquisition time and automatic daily clock sync (LoRaWAN)

What the sensor performs

• Alert: trigger alarms on fraud, threshold exceedance or leak detection
• Monitor: periodically report water, electricity and heat meter readings (index transmission, flow min/max)
• Count: count equipment cycles to anticipate maintenance
