November 28th – Oh my, this is a geeky thing. I spotted on the pavement near the Warwick Road near Sparkbrook. It’s a small, orange box with a radio antenna, and some kind of display. From it, there’s a signal cable popped through the access cover of a fire hydrant. There was nobody in sight and it just sat there, protected by a road cone.

This is actually part of a very clever water leak detection system made by SebaKMT, a measurement technology company. This rechargeable device is one of two recorders placed near a suspected water leak. An audio sensor is attached to the pipe beneath the cover from each recorder, and both units ‘listen’ to the noise made by the escaping water transmitted up the pipework.

The data from each is broadcast wirelessly to a third device, held by a technician, and that calculates the exact distance of the leak down the pipe from the sensors, by time lag in the audio signals recorded.

By taking several measurements, it can pinpoint within centimeters the place where engineers should dig to fix a leak that may not e evident on the surface. Such devices can save a huge amount of time and money to utility companies.

6th December – Today didn’t start well. A really, really bad journey to work saw me leave the house, return, leave again, just make the train, then sit for ages on it going nowhere just outside Birmingham New Street. When I finally got to Moor Street, the trains there were also not running, so I cycled into Tyseley. Instead of going via Small Heath, I chanced my arm at Camp Hill-Sparkbrook- Sparkhill, which seemed a decent route. 

There is some really great architecture in this corner of south east central Brum. I noticed particularly this old pub on the corner of Shakespeare Street and Warwick Road. I think it must be all flats now, but the terracotta brickwork, architraves and panels are a thing to behold. Sadly, the elegant clocks on the tower are stopped. Few things speak more eloquently of urban decay than a static public clock.
