A portable generator is disclosed including a mounting arrangement for positioning a wireless communication device on a control panel of the portable generator. The mounting arrangement includes a mounting platform formed from a composite material where the mounting platform is secured to a rear surface of a front panel of the control panel assembly. The front panel includes a transmission cutout. The mounting platform includes a transmission window such that a wireless antenna of the wireless communication device can be aligned with the transmission cutout. The portable generator further includes a fuel sensing device that generates both a visual indication and an output signal indicative of the level of fuel in a fuel tank. The output signal can be transmitted by the wireless communication device to a remote location for remote fuel monitoring.

A liquid surface detector includes a terminal, a covering portion, and a sealing film. The terminal includes a ridge portion between a first wall face and a second wall face. The terminal sends an electric signal relating to detection of height of a liquid surface. The covering portion covers the terminal. The sealing film is formed between the terminal and the covering portion and is put into close contact with the terminal and the covering portion. The terminal further includes a groove and two second slant faces. The groove has a V-shape in cross-section and includes two first slant faces. The groove cuts off in the V-shape the ridge portion of an area of the first wall face covered with the sealing film. The two second slant faces respectively connect together an area of the second wall face covered with the sealing film and the two first slant faces. A boundary portion formed by contact between the two second slant faces which are opposed to each other is continuous with a top portion of the groove.
