CHESTER wM-Bus is a remote energy metering device with wireless connectivity (NB-IoT/LTE-M/LoRaWAN). It enables efficient data collection from meters using the Wireless M-Bus protocol.
Applications: remote meter reading, water consumption monitoring, gas consumption monitoring, etc.
Battery-friendly wireless connectivity
The device transfers data over cellular networks (NB-IoT/LTE-M)
Configured wM-Bus sensors reading
CHESTER wM-Bus listens for configured wM-Bus T1 and C1 devices, aggregates the raw received packets and send them to cloud
10+ years of battery lifespan
From two Saft LSH 20 cells (size D), the device can run for a long time with one reading per week
Fast deployment and seamless integration
Use the HARDWARIO Manager iOS/Android app to set the device and integrate its data from HARDWARIO Cloud
In plastics production, conveyors are often used for granulation, where the granulate is transferred through a pipe directly from the hopper. In this case, a scale can be placed under the hopper and monitored to see precisely how the material in the hopper is decreasing.
In production, it is also possible to weigh crates of products or entire pallets. This makes it possible to identify whether all products are on the pallet or if any are missing. Thanks to continuous measurement, predicting when the pallet is full and needs to be replaced with an empty one is possible. For example, this method is also used when packaging various products with many smaller components.
Another use of the HARDWARIO CHESTER Scale is weighing gas cylinders. Even if the cylinder is heavy, regular measurements can show differences in filling loss. This makes it possible to predict when the cylinder will be empty and must be replaced.
Thanks to the innovative design of CHESTER wM-Bus, you can easily monitor gas, heat, electricity, and water consumption in apartment buildings and homes.
In addition, CHESTER wM-Bus can also help to measure apartment building energy bills accurately and precisely.
To avoid any gas leaks or backflow of water, CHESTER wM-Bus will continuously monitor any anomalies and report them back.
