Products Description
Round LPG Level Sensor for Right Multivalve
This round LPG level sensor is a resistive fuel-level sender for compatible right-hand LPG multivalves. It provides an electrical signal related to the remaining liquid LPG in the cylinder for use by a compatible autogas ECU or fuel changeover switch. DC 5V and DC 12V versions are specified, with customizable resistance characteristics.

How Does a Resistive LPG Level Sensor Work?
A resistive LPG level sensor converts the multivalve level indication into an electrical resistance signal. A compatible ECU or changeover switch interprets this signal to estimate the fuel remaining in the LPG tank.
The resistance characteristic must match the receiving system. Different ECUs and switches may expect different resistance ranges or empty-to-full signal directions.
This component measures fuel level, not LPG pressure. It should not be selected as a replacement for a gas pressure sensor or pressure regulator.
Electrical and Mechanical Compatibility
5V and 12V Electrical Options
The product specification lists DC 5V and DC 12V versions. The correct option must be selected according to the intended electrical circuit and sensor interface.
Custom Resistance Specification
Resistance can be specified for the intended application. Before production or replacement, confirm the required resistance at empty and full indication, the signal direction, and the ECU or switch input specification.
Right-Hand Multivalve Fitment
This circular sensor is intended for compatible right-hand multivalves. The mounting interface, orientation, connector and operating range should be checked against the original part.
Typical Applications
LPG passenger car conversion systems
Compatible right-hand LPG multivalves
Autogas fuel-level display systems
LPG changeover switch fuel indicators
Replacement of compatible level senders
OEM resistance-matching projects
Recommended Verification Before Installation
A correct installation requires more than matching the sensor shape. The electrical resistance curve, mechanical mounting and receiving circuit must all be compatible.
Confirm right-hand multivalve compatibility.
Check sensor mounting dimensions and connector configuration.
Identify the required 5V or 12V version.
Verify the specified resistance range and empty-to-full signal direction.
Have a qualified LPG technician verify the electrical installation and indication.
Inspection and Quality Requirements
For an OEM or replacement application, the relevant acceptance checks should include resistance measurement at specified indication positions, electrical continuity, connector inspection and mechanical fitment.
The actual test procedure, acceptance tolerances and certification documents must be confirmed for the supplied model. No specific test standard or certification is claimed here without supporting records.
Frequently Asked Questions
Can I use any round LPG level sensor on a right-hand multivalve?
No. The round shape doesn't tell you the whole story. Check the mounting, electrical connection and resistance curve. Two sensors can look identical and still give completely different readings.
Why does my LPG gauge show full when the tank is nearly empty?
Start with the sensor resistance setting. If the ECU expects a different resistance range or reversed signal direction, the display can be wrong. Also check the wiring and the multivalve level mechanism before replacing parts.
Can a 5V LPG sensor replace a 12V version?
Don't assume that. Check the electrical specification of the exact sensor and receiving circuit. The wrong version may give incorrect readings or cause electrical problems.
Does customizable resistance mean the sensor works with every LPG ECU?
No. Custom resistance helps match a particular system, but you still need the correct signal curve, connector and mounting arrangement. Get those details before ordering.
Is an LPG level sensor the same as an LPG pressure gauge?
No. One indicates the amount of liquid LPG remaining in the tank. The other measures pressure. They do different jobs and should not be treated as interchangeable.
