Claim Text:
1. A fluid level sensor for measuring a fill level of a hot melt adhesive within a receiving space that is at least partially defined by a sidewall and configured to receive adhesive to be melted, the fluid level sensor comprising: a plate element having an electrically driven electrode and a ground electrode operatively connected for measuring a dielectric capacitance of air and adhesive acting as a dielectric between said driven and ground electrodes, said ground electrode adapted to be electrically connected to the sidewall such that the sidewall forms at least a portion of said ground electrode; and at least one fastener mount connected to said plate element and adapted to receive a fastener for coupling said plate element into adjacent relationship with the sidewall, such that the dielectric capacitance measured by said plate element varies with the fill level of the adhesive.
