A wavelength encoded liquid level switch and its fabrication is experimentally demonstrated using two inline fiber Bragg gratings (FBG). Cladding of one FBG is removed by etching and it makes the FBG to be refractive index sensitive. Thus FBG became an on-off switch sensor to control the liquid level. Another FBG is used for temperature compensation. The sensor has good repeatability.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
