The LT-420 is a unique device used for water level indication on Section I boilers and other boiler feedwater applications.
The unit combines several standard features in order to satisfy modern boiler code requirements, and at same time address challenging aspects of water/steam level applications. ASME BPVC.I-2019 PG-60.1.1 requires a Remote Level Indicator (RLI), to continuously measure, transmit and display the water level in the control room. The RLI is a discrete system that monitors the water level, independent of the DCS. Paired with a GWR transmitter, the LT-420 provides a reliable solution for water level indication.
