Overview
The Blue Sea Systems 1811 is a gasoline tank sender for the Vessel Systems Monitor VSM 422. It uses non-contact ultrasonic sensing, can be calibrated for the individual tank through the monitor, and is intended for tank depths up to 24 inches.
This setup works well on boats where fuel is constantly moving in the tank. Digital filtering helps calm the reading when fuel sloshes in chop or during acceleration, and the lack of mechanical moving parts avoids the wear points that come with float-based arrangements.
Compatibility is straightforward: this sender is matched to the VSM 422, so the first fit check is the monitor already installed on the boat, followed by the tank type and depth.
Key features
- Made for gasoline tank level monitoring with the Blue Sea Systems VSM 422
- Non-contact ultrasonic sensing with no mechanical moving parts in the sender
- Per-tank calibration through the monitor for readings matched to the tank
- Digital filtering helps steady the displayed level when fuel moves inside the tank
- Suitable for tanks up to 24 inches deep
Compatibility and fit
Before ordering, confirm that the boat is using a Blue Sea Systems VSM 422 and that the gasoline tank is within the 24 inch depth limit. This sender is for fuel level monitoring on gasoline tanks, not for water, waste, or diesel applications.
Installation and setup
Installation centers on mounting the sender on the tank and then calibrating it through the VSM 422 so the displayed level tracks the actual tank shape and usable fuel volume. That calibration step matters most on boats with tanks that are not simple rectangles, where a generic level reading can be less helpful near the top or bottom of the range.
Use on board
This sender is a sensible match for owners already using the VSM 422 to keep several onboard readings in one place and who want fuel level feedback without a float mechanism. It also makes practical sense on cruising boats, fishing boats, and other hulls that spend time underway, where fuel movement can make unfiltered readings harder to trust.
