FRESH WATER SUPPLY SYSTEM FOR A RAILWAY VEHICLE

摘要

A fresh water supply system for a railway vehicle has a fresh water tank, a feed line extending from the fresh water tank for fresh water consumers to be supplied, and a valve that is located within the feed line for metered dispensing of fresh water. The valve is disposed at a lower level than a fresh water outlet of the fresh water tank. A pressure sensor is disposed upstream of the valve and it has a signaling connection to an evaluation unit. Typical characteristic pressure values for the fresh water supply system are stored in the evaluation unit and the evaluation unit detects discrepancies between the characteristic pressure values and the pressure values supplied by the pressure sensor. From this, a fill level of the fresh water tank and/or a flow velocity of the fresh water are estimated.
