A method for tightness control of a filling-sealing unit (1) for containers (9) is described. According thereto, a pressure chamber formed at the filling-sealing unit is sealed by way of a first seal around a sealer that is movable therein and by way of a second seal around a pressure supply that is movable therein. According to the invention, a third seal formed for sealing the pressure chamber around a container neck finish is sealed from the outside with an attachment, a positive pressure and/or negative pressure is generated in the pressure chamber, the pressure line used for this purpose is closed, and then a pressure profile in the pressure chamber is measured. This allows a leakage to be selectively detected at the first and/or second seal and be distinguished from a leak at the third seal.

Determining a sealing integrity of a steering assembly determining when the steering assembly is performing a steering event, determining an expected pressure change associated with the steering event, and receiving data from the pressure sensing member. During performance of the steering event, the controller analyzes the data from the pressure sensing member and determines when the pressure sensing member detects the expected pressure change and reduces an incident counter. When the pressure sensing member does not detect the expected pressure change, the incident counter is increased.

A gas-detecting apparatus, having a gas inlet and a gas outlet, for detecting a false alarm is disclosed. The gas-detecting apparatus comprises a control module, a sensor module, and an air chamber. In an example embodiment, the sensor module is electrically connected with the control module. The sensor module has a sensor inlet and a sensor outlet. The sensor inlet is fluidly coupled to the gas inlet of the gas-detecting apparatus. The air chamber has an air inlet and an air outlet, wherein the air inlet is fluidly coupled to the gas inlet of the gas-detecting apparatus and the air outlet is fluidly coupled to the gas outlet. The control module is configured to receive a first sensing signal for a first level of gas from the sensor module and determine whether magnitude of the first sensing signal is higher than a first threshold value. In an instance when the magnitude of the first sensing signal is higher than the first threshold value, the control module causes the air chamber to supply ambient air to the sensor module through the sensor inlet of the sensor module.

A system that monitors toilets for leaks using in-toilet monitors with pressure sensors that are placed underwater in toilet tanks. Monitors can be dropped into tanks without additional wiring or installation; they may be battery powered and may transmit data wirelessly. Data may be analyzed by a server that detects leaks or other malfunctions. Pressure data may be filtered to remove the effect of barometric pressure, to measure the height of water in the tank. The system may learn the flush pressure change pattern for each toilet; pressure changes that do not match this pattern may indicate problems such as leaks. Data may indicate the type of leak, such as an open flapper or a leaking valve. Toilet monitors may measure temperature, and the system may generate alerts when freezing appears imminent. The system may keep flush counts for each toilet to support maintenance and water consumption measurement.

A system for monitoring pressure within a volume defined by a wall has a housing and a manometer coupled to the housing having fluid therein. The manometer is coupled to the volume and has a fluid level corresponding to a pressure within the volume. A pressure sensor is coupled to the housing and is coupled to volume. The pressure sensor generates a pressure signal corresponding to the pressure within the volume. A controller is coupled to the pressure sensor and is programmed to compare the pressure signal to a threshold and programmed to generate an indicator based on comparing.
