THMYL was a prototype telemetry station installed in 1959, using a mechanical chart recorder and early solid-state pressure transducers. “WATS” denoted the Wye-Aber Telemetry String – a pre-digital network of 12 stations. Llandrwyd was node 4, sensor suite 4 (turbidity + temp), with alarm threshold 2 (critical).
