Keep the meters you have
A utility meter with a pulse output is already measuring what you need. The ZPC reads that output and puts the consumption on the network, so nothing is replaced, no supply is interrupted, and no meter has to be recertified.
Pulse Counter
ZPC-2X
Reads the pulse output of a water, gas, oil, heat or electricity meter and sends the count over the Zigbee mesh, so the meter stays where it is. Battery models count up to 4 Hz, mains models up to 40 Hz, on one channel or two.

Features
Meters it can read
- Water
- Gas
- Oil
- Heat
- Electricity
40 Hz maximum pulse rate, mains models
ZPC-20 and ZPC-22 catch pulses as short as 10 ms, on inputs rated up to 35 V DC.
Power
ZPC-10 and ZPC-12 run on battery, counting up to 4 Hz. ZPC-20 and ZPC-22 take a mains supply of 85–264 V AC.
Sealed against water and dust
An IP67 polycarbonate enclosure, rated to operate from −25 °C to 55 °C.
One ZPC, two meters
Dual-channel models, ZPC-12 and ZPC-22, count two pulse outputs at once. Counts are held in flash on the device until the Gateway has them.

Engineering tools
Used in
-
Water consumption monitoring for commercial buildings
Bring main and branch water meters into Edge through a Pulse Counter, keep each meter’s units and totals, and compare like-for-like periods. -
Boiler performance monitoring
A pulse counter on the fuel meter coming in, a heat meter on the way out, and the firing state that tells you which periods are worth comparing. -
Pulse meter remote monitoring
A counter on the meter's existing pulse output, the pulse weight recorded once, and a totaliser reading that lets you prove the counts later. -
Tenant submetering and cost allocation
Meter each tenancy, the landlord supply and common services, and export a dated record that reconciles with the main meter. -
Multi-site energy monitoring
A Gateway on every site reads the meters that are already there, applies one point list, and keeps the readings when the connection drops. -
Modbus meter integration for a BMS or SCADA system
A Modbus interface reads the meters and instruments on site, and Edge serves what it collects onward over Modbus TCP, MQTT or HTTP to the system that needs it.
Questions engineers ask
Battery or mains?
Battery or mains?
Battery models (ZPC-10, ZPC-12) count up to 4 pulses a second and need no supply. Mains models (ZPC-20, ZPC-22) count up to 40 a second. Choose mains when the meter can pulse faster than 4 Hz at peak flow.
Does it work with volt-free and active outputs?
Does it work with volt-free and active outputs?
Check which your meter has before you wire it: a volt-free contact or an active signal. The mains models take pulses up to 35 V DC, as short as 10 ms with 10 ms between them.
How is a pulse turned into litres or kWh?
How is a pulse turned into litres or kWh?
Each pulse is worth what the meter says on its plate or in its datasheet, such as 10 litres or 1 kWh. That value is set when the channel is commissioned, and the count is allocated to each reporting period to within ±1% at 60-minute intervals.
Can it go in a hazardous area?
Can it go in a hazardous area?
No. The ZPC is not Ex rated, so it must be installed outside any hazardous zone. Run the pulse cable out to it from the meter where the meter is in a zone.
The datasheet says Digital Signal Sensor. Why?
The datasheet says Digital Signal Sensor. Why?
The same datasheet covers the ZDI-20 and ZDI-22, digital-input models that report an open or closed state, from a door contact for example, instead of counting pulses. Ask us about the ZDI.
Can one ZPC read two meters?
Can one ZPC read two meters?
Yes. The dual-channel models, ZPC-12 and ZPC-22, count two pulse outputs at once and report each as its own channel.
