How to Measure Hot Oil or Chemicals When Standard Sensors Cannot Handle High Temperature? This is a common challenge in industrial plants:
Hot fuel oil (FO) Thermal oil systems Chemical storage tanks Low-height tanks High-temperature process vessels Many standard level sensors fail in these applications because of:
Temperature limitations Unstable readings Sensor damage Heavy contamination Incorrect measurement technology The CapFox EFT 20 AFRISO is designed specifically for these difficult environments.
CapFox EFT 20 AFRISO high-temperature capacitive oil level sensor CapFox EFT 20 AFRISO provides continuous oil level measurement with 4-20mA output for industrial tanks.
How Does CapFox EFT 20 AFRISO Work? CapFox EFT 20 works based on capacitive level measurement technology .
As the liquid level changes, the capacitance between the probe and the tank wall changes.
The internal electronics convert this change into:
4-20mA output 0-10V output This signal can be sent directly to:
PLC HMI SCADA AFRISO DA12 display unit Unlike hydrostatic transmitters, capacitive measurement does not depend on liquid column pressure.
This makes it highly effective for low tanks and hot media.
Working principle of CapFox EFT 20 AFRISO capacitive oil level sensor CapFox EFT 20 measures liquid level by detecting capacitance changes.

CapFox EFT 20 vs Hydrostatic Sensor DMU08 Criteria
CapFox EFT 20
DMU08
Technology Capacitive Hydrostatic High temperature Excellent Limited Low tank measurement Excellent Moderate Hot fuel oil Excellent Limited Calibration required Yes Minimal PLC integration Yes Yes
CapFox is generally better for more difficult industrial applications.
Comparison between CapFox EFT 20 AFRISO and DMU08 AFRISO CapFox offers better performance in high-temperature and chemical applications.
Practical Experience From practical field experience:
If the application is standard diesel storage:
→ DMU08 is usually more economical.
If the application involves:
Hot fuel oil Thermal oil Chemical liquids Low-height tanks → CapFox is the safer and more reliable choice.
Choosing the wrong measuring principle often leads to repeated failures and higher maintenance costs.
