Tank Level Monitoring

Solution description

Properly monitoring and managing levels inside tanks or reservoirs can help owners and asset managers increase productivity and profitability.

Level monitoring is a solution for level and volume monitoring of non aggressive, aggressive fluids and fuels based on ThingsLog low power data loggers and specially designed submersible level sensors.

The solution allow you to keep track of the exact levels in your tanks or reservoirs at any time. Customers are able to monitor if levels are increasing or decreasing and receive alarms whenever certain thresholds are reached. Theft or leakage thus can be immediately detected. At the same time it streamlines your service operations by allowing you to refill/empty only when needed.

How does it work?

Sensor details

Sensor is submerged on the bottom of the tank/reservoir. Depending of the type of the liquid there is ventilated/copper cable or stainless steel body from the sensor to the data logger.

Data logger operation

is waking up on configurable interval of time, provides power supply to the sensor, reads the measurement and records the value in memory. Logger wakes on configurable transmission interval and transmits the recorded readings.

If the reading is bridging a preconfigured low/high power threshold values the logger wakes up and transmits an instant alarm. Alarms are forwarded to the subscribed users through an email, mobile notification or an API message.
