CHESTER
Range

CHESTER Range is a configurable distance sensor with wireless connectivity (NB-IoT/LTE-M/LoRaWAN). It measures distance using an ultrasonic sensor - ideal for monitoring the level of liquids or bulk materials.

Applications: tank level measurement, bulk material height monitoring, object presence detection, etc.

Ultrasonic probe

Up to 4 external thermometer/humidity probes

Wireless data collection

Long battery lifetime

Typical use cases

Measurement in storage tanks is a big topic across agriculture. For example, measuring the bin level of wheat, corn, and other types of crops is very common. This makes it possible to know precisely how much is in the bin, allowing for better planning of subsequent supply or monitoring of the commodity due to online commodity exchanges.

Similarly, water in storage tanks or other liquids can be monitored. For rainwater harvesting, for example, it is beneficial to know how much water can be harvested at which times of the year, as this can be used to plan for possible expansion of storage tanks or to plan cash flow for water purchases, especially for larger farms where water consumption is high. Such a reservoir does not necessarily have to be a closed container because, with CHESTER Range, you can measure the water level in a pond or artificial reservoir.

A separate category of reservoirs is waste pits. These are polluted environments where robust sensors are needed. Ultrasound is an excellent choice in this respect. Measuring a sump is not just information for the owner of the sump. However, in the case of online monitoring, which is passed on to the companies that deal with the export of sumps, the export route can be planned as efficiently as possible, and, as a result, all involved can save money.

A completely different area where distance measurement can be used is monitoring natural areas and their displacement. This could be, for example, monitoring the height of snow for avalanche analysis. With CHESTER Range, critical areas can be observed very well and know in time if the snow cover in specific areas increases above the risk level.
