Abstract: A sensor unit support structure for supporting a sensor unit in a manhole. The support structure comprises an elongate beam adjustable along its length to span a width of the manhole and support the sensor unit within the manhole. The support structure further comprises first and second mounting brackets associated with respective first and second ends of the beam, each mounting bracket being configured to fasten the beam to an inner surface of the manhole. The support structure further comprises first and second temporary brackets associated with respective first and second mounting brackets. The first and second mounting brackets are configured to be removably coupled to the respective first and second temporary brackets, each temporary bracket being configured to engage a rim of the manhole to allow the first and second mounting brackets to be positioned in the manhole and temporarily supported in position until the mounting brackets are fastened to the inner surface of the manhole.

Abstract: A monitoring system for an access chamber to a pipe network. The system includes at least one sensor for determining a fluid condition associated with fluid in a conduit of the pipe network and at least one threshold level indicator for determining a threshold fluid level in the access chamber, the at least one threshold level indicator being associated with the at least one sensor. The system further includes a controller for receiving output signals from the at least one sensor and the at least one threshold level indicator and for controlling supply of power to the at least one sensor and a wireless transceiver in communication with the controller to allow the controller to communicate with a remote server over a communications network. The controller is arranged to supply power to the at least one sensor in response to receiving an output signal from the at least one threshold level indicator indicative of the fluid level having exceeded the threshold fluid level.
