摘要： A pair of float operated sensors simultaneously detect inflow into the housing of an alarm assembly to actuate a buzzer and a lamp providing an early warning back-up alarm. One of the sensors remains actuated by the holding action of a magnet to continue operation signifying back-up recession. Under selective control, the buzzer is operated in by-pass relation to the sensors to indicate a low voltage condition of the battery powering the alarm assembly.

摘要： A sewer line backup detection device and alarm are provided which can be installed in place of the cleanout access cap in a conventional sewer line. The device comprises a housing having male connecting threads adapted to fit standard female receptacles which have been used in the past to provide cleanout access to sewer lines, the housing containing alarm means or alarm transmitting means actuated by a pneumatic switch. The pneumatic switch is actuated by a flexible diaphragm which is fitted snugly onto the lower end of the housing which extends into the sewer line. In the event of a blockage of the sewer line, the blocked material exerts pressure on the flexible diaphragm which closes the pneumatic switch thereby setting off an alarm, either locally or at a remote location such as the dwelling from which the sewer line exhausts. The alarm system is utilized especially advantageously in combination with a detention tank located in the basement or lower level of a high rise building. In such a situation, a blockage is detected virtually immediately upon occurrence providing time to issue warnings to upper level users not to use the sewer system, thereby preventing an overflow at the first floor level and avoiding the damage and aggravation caused by such an overflow.

摘要翻译： 提供下水道备用检测装置和报警器，可以在常规下水道中安装代替清洁通道盖。 该装置包括具有阳连接螺纹的壳体，该螺纹连接螺纹适合于过去已经使用的标准母插座，以提供对下水道线的清洁通路，该壳体包含由气动开关致动的报警装置或报警传递装置。 气动开关由柔性隔膜致动，柔性隔膜紧密地安装在壳体的下端延伸到下水道。 在污水管线堵塞的情况下，堵塞的材料对柔性隔膜施加压力，该压力关闭气动开关，从而在本地或在诸如下水道排放的住宅的偏远位置处发出报警。 警报系统特别有利地与位于高层建筑物的地下室中的滞留池结合使用。 在这种情况下，在发生事件时几乎立即检测到堵塞，提供向不使用下水道系统的上层用户发出警告的时间，从而防止在第一层楼层溢出并避免由这种溢出引起的损坏和加重。

摘要： A sewer back up warning system includes a pair of electrically-conductive probe rods fixedly securable within a sewer clean out pipe and being in electrical communication with a sewer back up alarm. An electrically-conductive float is hingedly attached to a free end of one of the rods, such float serving to rise in the clean out pipe as a sewer backs up so as to eventually come into contact with the second rod to thus complete the electrical circuit containing the back up alarm. A corrosion check device is also provided which essentially consists of a manually-operable chain pull for effectively bringing the metallic float into electrical communication with the second rod so as to determine the presence of corrosion build up which would prevent the operation of the alarm. The rods may either be retained in a non-metallic disk positionable within a sewer clean out pipe at the time a dwelling is constructed or alternatively, the rods may be inserted directly through the sewer clean out pipe cap in dwellings that have already been built.

摘要： The present disclosure relates to wastewater management that provides a method and a system for monitoring a sewer manhole from a remote location. The sewer monitoring system configured in a sewer manhole receives measured values from a level sensor and determines an accuracy error in the measured values for different conditions. The sewer monitoring system resolves the accuracy error in the measured values to obtain accurate measured values by either measuring a level of wastewater in the sewer manhole by setting a first range limit for the measured values dynamically based on an actual depth of the sewer manhole, or iteratively measuring the level of wastewater in the sewer manhole by setting unique a second range limit for the measured values dynamically. A risk associated with the sewer manhole based on the accurate measured values of the level sensor is determined, for monitoring the sewer manhole from a remote location.

摘要： The present disclosure describes systems and apparatus for detecting an impending sewer backup by detecting fluid undulations of predetermined magnitude inside a main body of a backwater valve. When at least a predetermined number of fluid undulations of predetermined magnitude are detected within a predetermined time period, an alarm can be triggered. Such undulations can be detected by monitoring a buoyant gate in a normally-open backwater valve to detecting instances of movement of the gate from a lowered position in which fluid flow from an inlet through the backwater valve is unobstructed by the gate toward but stopping short of a raised position in which the gate closes the inlet to obstruct fluid flow through the valve. For example, a sensor can be carried on the gate to detect movement of the gate. Alternatively, fluid levels inside the main body can be monitored directly.
