Pulse data loggers record the pulse-output signals produced by flow meters, water and gas meters, energy (kWh) meters, anemometers and other sensors that send a contact-closure or voltage pulse for each unit measured. By counting and time-stamping those pulses, a pulse logger turns any pulse-output device into a complete data-recording system — ideal for flow-rate monitoring, utility sub-metering, energy audits, traffic and event counting, air-speed logging and frequency recording.
Pacific Sensor Technologies supplies a full range of pulse counters and pulse data loggers for Australian industry, from compact single-channel units to multi-input industrial recorders. Choose a wired USB pulse logger for stand-alone deployments, or a wireless pulse logger with NB-IoT or Bluetooth for remote and IoT monitoring. Leading brands in stock include MadgeTech (Pulse101A, RFPulse2000A, Titan S8), COMET (U7844, M1300 series) and EFENTO wireless pulse sensors.
Typical applications include water-meter pulse logging, flow-meter data logging, energy / kWh metering, gas metering, rainfall tipping-bucket counting and machine-cycle event counting.

Most electricity, gas and heat meters provide a pulse output — a contact closure or voltage pulse emitted once per unit consumed, usually expressed as impulses per kWh. Connecting an energy meter data logger to that output turns a meter you already own into a complete consumption-recording system, with no need to replace the meter or interrupt supply.
Using a power meter data logger to capture those pulses gives you an independent, time-stamped record of consumption — the basis for sub-metering, audits and demand analysis:
Four things determine the right choice. First, your meter’s pulse constant (impulses per kWh) — this sets how fast pulses arrive and how the logger converts counts back into kWh. Second, the output type, either a contact closure (reed or solid-state) or a voltage pulse. Third, how many meters you need to record at once. Fourth, how you want the data — downloaded on site, or sent automatically from a remote location.
For a single meter logged on site, the MadgeTech Pulse101A is the simplest option. For remote or hard-to-reach installations, the EFENTO Pulse loggers report wirelessly over NB-IoT or Bluetooth. Where several meters or mixed measurements are involved, the COMET U7844 offers two pulse plus two dry contact inputs, while the COMET M1300 records current, voltage and pulse over Ethernet — useful when energy pulses sit alongside other electrical signals.
Not sure which suits your meter? Send us the pulse constant and output type from your meter’s data plate and our Australian technical team will match a logger to it.
Choosing the right pulse data logger comes down to four things: the type and speed of your meter’s pulse output, whether you need wired or wireless data collection, how many inputs you’re logging, and the environment the logger will live in.
Start by checking your meter’s pulse specification — the pulse rate (pulses per litre, m³ or kWh) and whether it uses a contact-closure (reed switch) or voltage pulse. Then match it to a logger with a high enough maximum pulse rate and the right input type.
For remote sites, choose an NB-IoT or 4G wireless models; for stand-alone audits, a wired or Bluetooth logger is simplest and most cost-effective.
A pulse data logger is a recording device that counts and time-stamps the pulse-output signals from meters and sensors — for example one pulse per litre from a water meter or one pulse per kWh from an energy meter. It converts those pulses into a stored data record of flow, consumption or events over time.
It connects to a device’s pulse or contact-closure output. Each time the meter sends a pulse, the logger increments a count and records the timestamp. Software then converts the pulse count into engineering units (litres, m³, kWh, etc.) and shows totals, rates and trends.
State loggers record on/off status changes, event loggers record the time each event occurs, and pulse loggers count high-frequency pulses within each interval — best when pulses arrive too quickly to log individually. See our detailed guide ‘Choosing between state, event and pulse data loggers’ for examples.
Yes. Water-meter pulse logging is one of the most common uses. As long as your water meter has a pulse or reed-switch output (e.g. 1 pulse per litre or per 10 litres), a pulse logger will record consumption for sub-metering, leak detection and billing verification.
Yes. Most electricity and gas meters provide a pulse output proportional to consumption. A pulse logger records these for energy audits, tenant sub-metering and demand profiling. Match the logger’s maximum pulse rate to your meter’s output frequency.
Wired/USB pulse loggers (e.g. MadgeTech Pulse101A) are downloaded on-site and suit stand-alone use. Wireless pulse loggers send readings automatically — EFENTO and COMET offer NB-IoT and Bluetooth models for remote, real-time and IoT monitoring without manual downloads.
Different models support different maximum pulse rates, contact-closure and voltage-pulse inputs, and channel counts. Check each product’s specification, or contact us with your meter’s pulse rate and output type and we’ll recommend a suitable logger.
Our pulse loggers range from around $128 to $3,925 depending on channels, connectivity and accuracy. All models are stocked and supported locally in Australia with fast delivery and technical assistance from our team.
Yes. Most electricity meters output a pulse proportional to consumption, stated on the meter as impulses per kWh. A pulse logger counts and time-stamps those pulses, so the readings convert directly back into kWh for sub-metering, energy audits and demand profiling. Check your meter's pulse constant and whether it uses a contact-closure or voltage output, then match a logger that supports that input type.
