Potentiometers 45 are designed to point to a foreign body that selects a certain amount that even small real echoes, if they are stretched in the direction transverse to the direction of movement of the interfering fog, have the gas discharge tube to the measuring vehicle, since the tip brings about several ignitions, so that this now continues to burn, curves occur, while with the stool 74 one and that up to the terminal c of the transmission pulse the io such transverse extent is apparently small or opens temporarily at the tube 50. So when the tube begins at this point. The tip 74 shows especially 44 is opened by the Edio, arises on the other clearly, that at this point the bottom echo secondary side of the transformer 54 is suppressed a sharper by the pre-echo. This suppression impulse, which corresponds to the use of the breakover voltage and so the bottom echo in the case of multiple registration, corresponds to the use of the echo. Expediently, the advantage that there can be no doubt is that this impulse is normally again amplified before it is fed to the writing device for which profile curve the small echo device is fed.

Claims

When setting up after net that the echo signal in per se known the main patent are Mehrfachecuos against it Way of a bistable flip-flop circuit is much more disruptive because there is echo between the ground, that caused by the first echo in one of the sta curves and the associated multiple echo curves bilen state and due to the transmission pulse in the io other ground echo curves occur., so that the another stable state is transferred, and clarity and clarity of the presentation is not that the differential quotient of the breakover voltage is more guaranteed. It is therefore necessary for this is fed to the registration device. Take care that the paper is below a

The invention is therefore based on the object, namely the multiple echoes and those with high sensitivity very long tail of the bottom echo, but not the weak ones preceding the bottom echo Suppress echoes. This is what makes this job

The subject of the main patent is a registering 40 that the echo sounder device for measuring water referred to in claim 8 of the main patent consists in the fact that the road has a bistable flip-flop circuit by recording longitudinal profiles, the plurality of transmitter Receivers that are distributed on a measuring ship through the first echo in the one stable state across its direction of travel and are assigned to the other stable state by the transmit pulse of the following plumbing period and to which just as many registrations are 45 in the other stable state are, which on a common that the differential quotient of the tilting voltage of the rotating girders in the running direction against each other is fed to a registration device,
There are already echo sounders for a single measurement profile curves with offset zero lines are known, which record from an integrating display on a common writing surface, or make use of a recording device, which is only characterized in that a single echo signal in each plumbing period verarbeider constant spacing of the registration elements smaller th can. There, a flip-flop circuit controlled by the first is as the difference echo measured on the recording scale and the following transmission pulse between the maximum and minimum value is used, which is a current of the water depth to be recorded. The latter means a pulse of constant amplitude is generated, the duration of which depends on the arrangement according to FIG.
