The configurable NB-IoT/LTE-M/LoRaWAN device that counts pulses on four digital inputs.These pulses can be transformed to actual values.

The CHESTER Counter catalog application allows connecting up to 4 counters for measuring pulses. These pulses can be transformed to actual values for measuring flow of water, gas or LED pulses to check working state.

Four digital
input counters

Use digital NPN/PNP inputs to count pulses from electricity meters, water meters, gas meters, or PLCs.

wireless connectivity

The device transfers data over cellular networks (NB-IoT / LTE-M) or public/private LoRaWAN networks.

Reliable operation from a
single battery

CHESTER Counter is designed to operate on just a single primary lithium cell for a great period of time.

Fast deployment and
seamless integration

Use the HARDWARIO Manager iOS/Android app to set the behavior of each input and integrate its data from HARDWARIO Cloud.

Application areas

Typical use cases

Thanks to our meticulous design philosophy, you can remotely collect values from various electricity, water consumption and gas meters installed in hard to reach places.

By connecting CHESTER Counter to infrared gates you can log and monitor the number of people at various transition or transport stations to ensure smooth traffic and operation.

Among other applications, you can use CHESTER Counter to track the yield on production lines and thus ensure the overall production is always up to speed without downtime.
