The AHD-SW I and AHD SW II tank overfill warning indicators facilitate the fuel intake process. Installed within sight of the tank filler neck, they can significantly minimize the risk of overfilling during refueling. The indicator modules thus make an effective contribution to water and environmental protection. The AHD SW II variant has identical dimensions and is designed for monitoring two tanks.
The quantitative tank level is continuously displayed via an LED scale. If a configurable warning limit is exceeded during refueling, the yellow LEDs on the front flash and an interval signal tone is triggered. When the maximum fill level is reached, the red LEDs flash and the acoustic signal switches to a continuous tone. After an alarm has been triggered, the signal tone can be muted using the button on the front. If a tank can be filled from several locations, the devices can also be connected in parallel so that the fill level can be read at each tank nozzle.
The AHD-SW I and AHD SW II display modules work in conjunction with the AHD-SAS 15 analog data station, which records the tank sensors. This means that all messages can also be visualized on the existing display panels of the ship alarm system. As part of modern yacht equipment, AHD-SW I and AHD SW II offer an innovative and useful extension to the Böning ship alarm system.
