What is Pulse Counting
Pulse Counting is the measure of electrical pulses during a specific amount of time, by a mechanical contact (a sensor, digital input, reed switch) on a device. This feature is common on meters that detect flow – gas meters, electrical meters, and water meters, such as a rain gauge to monitor rain rate and total rainfall.
Pulse counting is supported on the following Digital Matter devices*:
Eagle
Falcon
SensorData LoRaWAN®
SensorNode LoRaWAN®
How does Pulse Counting work?
The mechanical contact is generally open and will close when a magnet is close enough in proximity. In a rain gauge, this will activate (open and close) when water passes through the meter. The closure and opening of this switch creates an electrical signal, which is considered a single ‘pulse’. For example, in a water meter each of these pulses represents a predetermined volume of water passing through the meter.
Our devices report the pulse count and will store the records in our non-volatile flash memory, meaning that if there is a network error, records will not be lost. The count is also maintained across a device power outage – meaning you never lose important data. The devices also have industry-leading battery life and reliability of up to 7 years, so they are ideal for long-term monitoring.

*The pulse counting feature is also available on the Dart2, G62, and G120, however it is not standard.
