FQ4510 Low-Range Submersible Liquid-Level Pressure Transmitter

Low-range submersible pressure transmitter for 1–15 PSI liquid-level measurement where shallow tanks, canals, and low head pressure require higher sensitivity.

The FQ4510 extends the submersible liquid-level platform into lower pressure ranges for shallow tanks, canals, and lower head-pressure applications. It uses the same sealed, vented-cable construction as the FQ4500, with ordering ranges optimized for low-level measurement.

FQ4510 Low-Range Submersible Liquid-Level Pressure Transmitter
Best For
  • ▶Shallow tanks, canals, and low head-pressure liquid-level measurement
  • ▶Groundwater and irrigation channels
  • ▶Low-range submersible applications from 1 to 15 PSI
  • ▶Wastewater and process tanks requiring higher level sensitivity
  • ▶Lower liquid columns where FQ4500 ranges are too high

For higher liquid-level ranges from 20 to 100 PSI, review FQ4500 Submersible Liquid-Level Pressure Transmitter.
