Why Does My Car's Fuel Gauge Show False Readings on Hills?

Click For Summary
SUMMARY

The discussion centers on the issue of inaccurate fuel gauge readings in vehicles when driving on hilly terrain. The user seeks a solution to obtain accurate fuel level readings using a gyro and known resistance from the fuel tank. A recommendation is made to explore various fluid level measurement methods, with the sight gauge being highlighted as the most reliable option for consistent readings.

PREREQUISITES
  • Understanding of fuel gauge mechanics
  • Familiarity with gyroscopic sensors
  • Knowledge of resistance measurement techniques
  • Basic principles of fluid level measurement
NEXT STEPS
  • Research fluid level measurement techniques, focusing on capacitive and ultrasonic sensors
  • Explore the implementation of gyroscopic sensors in automotive applications
  • Learn about the design and functionality of sight gauges
  • Investigate calibration methods for fuel gauges in vehicles
USEFUL FOR

hello
i am new here. I am facing a problem in fuel gauge that when i drive for a long time on hills it start to show false value. I decided to solve this problem i have a gyro and known resistance from fuel tank of my car and now i want to have true value all the time please help me with it or suggest any other method.

How about this? http://www.sensorsmag.com/sensors/leak-level/a-dozen-ways-measure-fluid-level-and-how-they-work-1067

You should do your own research before posting questions here.

Edit: In addition to the dozen methods above, l should mention the most reliable of all methods. I use it on my boat -- the sight gauge.
