with the dead zone, the device will not measure properly.
f) If the maximum level in the tank gets into the dead zone, the device shall be mounted into a higher installation
neck. The tank can be then filled nearly up to the maximum volume. The neck’s inner surface shall be even and
smooth (without edges and welded joints), the inner edge should be rounded in the spot where the ultrasonic wave
leaves the pipe. Choose the largest possible neck diameter, but keep the neck height as low as possible. The
recommended dimensions of
a) The device is installed in a vertical position into the upper lid of the tank or reservoir using a lug, a fastening nut or
a flange in such a way that the axis of the device is perpendicular to the surface level of the measured liquid (Fig. 1).
Tightening of the level meter in the welding flange (or. by the fixing nut) is done by hand *. The device shall be
installed in places with no risk of mechanical damage to the front of the sensor.
b) The minimum dimensional parameters when installing into the lid or
the ceiling of the tank are listed in Fig. 3.
c) When installing in an open channel (sump, drain, etc.),
install the device onto a console as close as possible to the expected
maximum level.
d) The reference plane for the measurement is the lower
edge of the transducer (Fig.2). In compliance with the measuring
principle, no signals reflected in the area directly below the device (dead
zone) can be evaluated.
The dead zone (Fig. 2) determines the minimum distance possible
between the device and the highest level. The minimum distances to the
medium are listed in the chapter "Technical specifications".
e) The device shall be installed so that the surface does not interfere with
the dead zone when the tank is filled to the maximum. If the measured
surface interferes
