will now indicate the current level in the tank or well
(0 m immediately after initial startup) and is now in service
as a regular level meter, i.e. without the use of the relays and
the analog output for control / alarm.
See the next section for basic settings.
35 cm from sensor
Level read-out = distance
between sensor and bottom
- (minus) the distance be-
tween sensor and surface.
At the same moment Shuttle
®
registers an echo, the zero point is automatically set to the
level that is present in the tank or well.
Furthermore, the mA output is set to 4 mA at the current zero point and 20 mA at a level cor-
responding to a distance of 35 cm from the ultrasonic sensor.
