Auto Fluid Level Sensor

General fluid level sensor hub

Non-SCR fluid level sensors for coolant, washer, fuel, oil, hydraulic and industrial tanks

Use this page for general automotive and industrial level sensing. DEF / AdBlue / urea SCR tank sensors are kept on a dedicated hub and catalog to avoid mixed buyer intent.

Included scope

  • Coolant, washer fluid, fuel, oil and hydraulic level sensors
  • Marine, industrial, BEDIA and reed-switch level monitoring sensors
  • OE/photo confirmation for replacement and project sourcing

Separated scope

  • AdBlue / DEF / urea SCR tank level sensors
  • Reductant quality-level headers and SCR tank modules
Automotive / Industrial Fluid Level Sensor

General fluid level sensors for coolant, washer fluid, fuel, oil, marine, industrial, and heavy-duty tanks.

This page is the main directory for non-SCR fluid level sensing. Use it for coolant level sensors, washer fluid level sensors, fuel / oil / hydraulic monitoring, reed-switch float sensors, BEDIA industrial level monitoring sensors, and other automotive or industrial tank-level applications.

How this page differs from AdBlue / DEF

  • Included here: coolant, washer fluid, fuel, oil, hydraulic, marine and industrial level sensors.
  • Included here: reed-switch float sensors, conductive probes, industrial level monitoring modules and general replacement sensors.
  • Excluded here: AdBlue / DEF / urea SCR tank level sensors, which have their own dedicated page.
Looking for SCR / DEF tank parts?

AdBlue / DEF / urea level sensors are separated to avoid mixing search intent and buyer requirements.

General fluid level sensor selection details

  • Tank medium: coolant, washer fluid, oil, fuel, hydraulic fluid, water, or industrial liquid
  • Sensor length, float travel, mounting thread/flange, connector and cable orientation
  • Output type: switch, resistive, analog, conductive, reed-switch, or custom signal
  • Environment: temperature, vibration, chemical compatibility, and installation position
