1. A data logger device for connection to an air pressure supply line to an air motor driving a flexible cleaning lance hose drive apparatus, the device comprising:
a housing removably fastenable to a pressurized air supply line to an air motor driving a flexible lance hose drive apparatus;
a pressure transducer operable to continuously monitor air pressure within the air line in real time; and
a datalogging processor and memory communicating with the transducer for recording data from the transducer and providing an input to automated lance hose drive control circuitry that initiates one or more of (a) automated lance reversal operations upon sensing an obstacle in a tube being cleaned by a cleaning lance driven by the drive apparatus and (b) cleaning fluid pressure dump operations upon sensing an unexpected event.
