A septic system level detection system includes a means to detect a fluid level within a septic system that indicates a failure or possible impending failure of a septic system and means to communicate an alert of this indication via electronic messaging media. A digitized record of information related to the identified septic system is stored in a database. Upon receipt of a septic system failure alert, at least a portion of the digitized record of information is transmitted via an electronic communications system network, i.e., a network comprising a telephony network and/or the Internet, to a predesignated address of the network.

The invention relates to a submersible system (1) for measuring the density and/or concentration of solids in a dispersion, which can be in the form of a liquid, a mixture of multiple liquids, a suspension of solids in liquid, or a combination of these forms, inside of a reactor (11) into which gas in the form of bubbles is introduced, the system comprising: an open, pass-through gas exclusion device (4) having a tubular body (5) with a variable cross-section through which the dispersion without gas bubbles enters, the device coupling to an inlet tube (6); a scaled chamber (8) that has a means for measuring density, when the dispersion circulates between an inlet (14) of the sealed chamber (8) and an outlet (15) of the sealed chamber (8). The outlet (15) of the sealed chamber (8) is coupled to an outlet tube (7) through which the dispersion returns to the reactor (11) in which same is being processed. The system also comprises a transmitter (9) connected to a sensor, which generates an output signal proportional to the density of the dispersion without gas bubbles by means of the sensor located inside the sealed chamber (8); and a processing unit (10) that generates an output signal (16) proportional to the concentration of solids in the gasless dispersion, as well as the pulp density. The invention further comprises a method for obtaining the concentration and density of the pulp.

An apparatus and method of determining the level of a liquid in a reservoir having curved surfaces is described, where the measuring device comprises a support having a radius of curvature conformable to the curvature of the reservoir. A float assembly is captivated to the support so that it may move freely in the vertical direction, but is constrained in rotation with respect to the support by compatible asymmetrical structural features. The float assembly includes an element that can be sensed by a sensor assembly that is positioned along the support over the length of the support encompassing the range of fluid levels to be measured.

A liquid level detecting apparatus of a tank for a vehicle is provided. The apparatus includes a main detecting part that detects the liquid level of the liquid in a tank to output a liquid level detection signal corresponding to the liquid level and an auxiliary floater assembly that has an auxiliary floater provided to float on the liquid surface of the liquid in the tank. A gyro sensor is mounted to the auxiliary floater, and an angle detection signal corresponding to an inclined angle of the tank is output by the gyro sensor. A controller determines a final liquid level value by correcting a liquid level value obtained from the liquid level detection signal based on the angle detection signal.

A flood sensor apparatus configured to send a signal to a computing device causing the computing device to turn off a utility at a site experiencing a flood. The flood sensor apparatus may include a housing and a back cover which, when coupled together, form gaps along a perimeter of the flood sensor apparatus such that fluid (e.g., water) may quickly fill and drain an interior of the housing. These gaps may be large enough such that the fluid may quickly fill and drain the interior of the housing but small enough that debris may not clog the gap or enter the interior of the housing. The back cover may include a rib extending from an inner face of the back cover and that that runs along a perimeter of the inner face. The rib may prevent tampering of a flood sensor located in the interior of the housing by blocking any object that may be inserted into the gaps.
