No more blind spots in complex or constrained tanks.
FoxPressure Gen 4 uses hydrostatic pressure sensing to cover deep, narrow, and geometrically complex tanks where radar cannot deliver stable readings — extending your planning data to every tank in the network.
Built for distributors operating tanks where radar measurement is not feasible.

Hydrostatic Monitoring for Demanding Tank Environments
FoxPressure (Gen 4) is a hydrostatic pressure-based level sensor for deep, narrow, or geometrically constrained tank installations. It is used where radar-based sensing cannot deliver stable, reliable readings — enabling accurate level data in tanks that would otherwise be difficult or impossible to monitor.
It integrates into FoxPortal to support consumption-based forecasting, refill planning, and portfolio-wide visibility.
Core Capabilities
Measurement & Hardware
- Accurate level data from tanks that would otherwise be invisible — deep, narrow, or geometrically constrained
- Hydrostatic pressure measurement works regardless of tank shape, internal obstructions, or line-of-sight
- Stainless steel probe rated for long-term submersion in industrial liquids — IP68 throughout
- Weatherproof housing for demanding outdoor and underground installations
- On-device display for instant on-site level checks without opening the app
Connectivity & Power
- Multi-network connectivity adapts to any site infrastructure — NB-IoT, LTE-M, 2G, Wi-Fi, or Bluetooth
- Integrated eSIM eliminates SIM card logistics across large fleets
- Long battery life even in hard-to-access or underground locations
- 5 m probe cable reaches the base of most heating oil and diesel tanks
Where FoxPressure Gen 4 Fits
FoxPressure Gen 4 is the right choice when tank geometry or installation conditions prevent reliable radar measurement.
- T-piece installations — radar produces erratic or incorrect readings in this configuration
- Deep or narrow tanks where radar line-of-sight is not achievable
- Tanks with internal cross-bracing, edges, or obstructions
- Underground fuel storage with constrained or angled access
- Heating oil tanks with complex internal geometry
- Industrial fluid storage where mounting constraints prevent radar use
Industry applications: Heating Oil · Diesel · Lubricants
Ideal Use Cases
- Heating oil and diesel tanks with complex geometry, T-piece connections, or deep profiles
- Underground tanks and sites with constrained or angled access openings
- Installations where radar cannot deliver stable, reliable readings
- Distributor portfolios requiring complete tank coverage across all tank types
Deployment Requirements
- Requires a suitable threaded opening or compatible adapter for probe insertion
- Standard probe covers approximately 3.5 m depth for heating oil and diesel (0–300 mbar)
When to Use a Different Sensor
FoxPressure Gen 4 is not the default sensing option. Consider an alternative when:
- Radar measurement is stable and feasible for the tank type (→ use FoxRadar Gen 4)
- No suitable threaded opening exists for probe insertion
- Installation constraints favour fully contactless measurement
- The environment requires ATEX/IECEx certified hardware (→ use Pressure EX)
Role Within the FoxInsights System
- Accurate level data from complex and constrained tank installations
- Data transmission to FoxPortal for consumption analysis
- Full inclusion of difficult tanks in consumption-based forecasting
- Reliable planning input across all tank types — not just standard ones
Execution remains with your operations team.
Integrated with FoxPortal
