Black Hill Transmitter is a facility for FM and TV-broadcasting at Black Hill, Scotia (national grid reference: NS828647 ) on the eastern outskirts of Glasgow, Scotland. It uses as antenna mast a guyed mast approximately 305 metres tall, which was built in 1961. Glasgow (or Glaschu in Gaelic) is Scotlands largest city and unitary council, situated on the River Clyde in the countrys west central lowlands. ...

intelligent d/p transmitters can--based on their own measurements--automatically switch ranges between two calibrated spans (one for 1-10%, the other for 10-100% of FS d/p), it should be possible to obtain orifice installations with 1% AR inaccuracy over a 10:1 flow range.
Segmental wedges can measure flow in both directions, but the d/p transmitter must be calibrated for a split range, or the flow element must be provided with two sets of connections for two d/p transmitters (one for forward and one for reverse flow).
Transmitters usually detect the float position through magnetic coupling and are often provided with external indication through a rotatable magnetic helix that moves the pointer.
Scottish naturally were interested when they heard that the ITA had a transmitter near Perth in their considerations, and tried to lay claim to it.
Although the transmitters themselves were expected to be available at the same time, give or take a week, linking them together, and to the network in Glasgow proved to be problematic.
The BlackHilltransmitter had at more or less the same time finally been improved, and their reception was no longer sub-standard.
