A self-installable radar monitor with built-in connectivity, so you can check levels remotely and stay informed without needing to be near the tank.
Built for locations where regular remote visibility matters.
SENTRi is for users who want more than local checking. It is built for remote visibility, autonomous updates, and dependable access to level information without relying on someone being nearby with a phone.
SENTRi is a strong fit for farms, remote properties, holiday homes, distributed assets, mobile tanks, and business-critical sites where regular remote updates are important. It is also the right option when businesses want autonomous monitoring across multiple customer sites.
SENTRi makes it easier to keep track of tanks from wherever you are. With remote app and dashboard access, you can view level, usage, alerts, and changes without needing to be near the tank.
SENTRi has been designed to keep installation simple, much like HAWKi. The key difference is that, because SENTRi is a connected remote monitor, setup includes a signal-check step to make sure the device is installed in the right place for dependable network performance. Beyond that, the aim is still quick, straightforward setup.
SENTRi sends data automatically using supported low-power cellular networks, so users can monitor tanks remotely without relying on a nearby phone or local Wi-Fi. This makes it especially useful for remote, unattended, or operationally important sites.
SENTRi is built to support both plastic and metal tank configurations, with installation approaches that make it practical across domestic, agricultural, and commercial scenarios, including peel-and-stick / pre-drilled options for plastic tanks and 1.5" / 2" BSP adaptor compatibility for metal tanks.
For applications where knowing where the asset is matters as much as knowing how much product is inside it, the optional GPS version of SENTRi combines radar-based level monitoring with location tracking in one device.
This is especially relevant where tanks move between sites, are deployed temporarily, or need both contents visibility and location visibility at the same time.
SENTRi combines remote connectivity with radar-based sensing, giving users the benefit of autonomous monitoring without losing the accuracy and stability that make the Magnus system useful in the real world.
One of SENTRi’s biggest strengths is that it keeps working in the background. It is designed to provide regular updates and support more dependable alerting, helping users stay aware of low-level conditions, unusual changes, or issues that matter operationally.
SENTRi works well as a standalone remote monitor, but it also fits naturally into the Magnus platform for businesses that need visibility across multiple customers, sites, or assets. The same system that helps an individual user stay informed can also help a service provider monitor and plan at scale.
The comparison document states that HAWKi and OMNi/SENTRi work on the same device-agnostic platform with the same forecasting and alerting logic.
