Vessel speed detecting device |
摘要 |
A vessel speed indicating device including a semiconductor pressure detector that detects dynamic pressure and outputs a signal indicative of this pressure. A speed indicator and calculator is incorporated which senses when the speed is below a speed at which high accuracy can be expected and outputs a warning signal in the event of that condition. Alternatively, when the device is operating in a range where the speed signal is accurate, actual speed is indicated.
