A simple fiber optic technique is developed for the remote measurement of the liquid level. It utilizes the static pressure, applied by the liquid, to measure the liquid level. A diaphragm type basic sensor is used to convert the pressure into deflection and deflection of the diaphragm is used to modulate the light falling on it. The resulting optical signal, containing information about the liquid level, travels through the optical fiber up to the earth station where it is converted into electrical signal, by the receiver, based on photo diode. It has been calibrated up to 70 cm depth in a water tank when the receiver is kept at a distance of 20 meters..

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.
