Telemetry Water Level - this was used by the water company to automatically indicate the height of water in a reservoir. The water company central office would dial the access number and listen to this cacophony coming from the pump house at the reservoir. The bell indicates 'feet' and the fart indicates 'inches'. The device at the reservoir was not electrically connected to the telephone line. It was a mechanical device which actually lifted a telephone receiver to answer the call and then made the noises into the handset! This overcame any legal problems with interconnection.
