A sensor for measuring fluid level is provided that includes a float, which may be steel or another material that affects magnetic flux. The sensor further includes a housing defining a cavity configured to receive the float. The housing may be, but need not be, tubular, and the cavity may be cylindrical. At least one magnetic coil is wound to the housing along the cavity. The coil may be wound around the housing. The float is positionable in the fluid to move within the cavity in relation to fluid level.
