NDTV-2 Drum Water Level TV Monitoring System
1. Overview
NDTV-2 drum water level television monitoring system can monitor all kinds of boiler water level direct-reading, the images will be directly fed into the central control room, providing a reliable data for boiler operators to accurate operation. The system can also monitor the boiler furnace externally, and reflect the true position of drum water level.
