Oorzaak:
Het gat in de tank is te klein waardoor de
kraag aan de onderzijde van de sensor op
de tankwand rust.
De sensor is aan de onderzijde vervuild.
De tank is hoger dan de maximaal te meten
hoogte.
vetus®
Ultrasonic level sensor - Analogue version
Introduction
The ultrasonic level sensor measures the liquid level in tanks without making any
contact. The sensor is suitable for drinking water, fuel (both diesel oil and petrol) and
dirty water (both black and grey water) and can be used in combination with every
Vetus level meter and with the control panel for dirty water (WWCP). The sensor
does not work when applied on metal tanks.
When the power is switched on the LED on top of the sensor will always flash
green!
Included in the delivery
1 Ultrasonic level sensor
1 Packing
5 Fixing screws
1 Installation instructions
Installation
N.B. If the sensor is installed in a tank that is full or partly full it must be cali-
brated before it is installed.
Install the sensor first if the tank is empty.
Cut a fitting hole in the highest horizontal surface of the tank at least 5 cm away from
walls and wash bulkheads as shown in the drawing.
The sensor has a 5-hole SAE fitting flange. Clean the inside of the tank after cutting
the fitting hole.
Fit the sensor using the packing and screws provided so as to obtain a vapour-proof
seal. If screws other than those supplied are used the maximum diameter allowed
is 5 mm!
Connect the sensor to the level meter as shown in the wiring diagrams and carry out
the calibration procedure.
Calibration
The sensor has to be calibrated for the internal height of the tank.
Only for a filled tank or a tank without a flat bottom (for example a V-shaped
tank):
Measure the internal height of the tank; set up the sensor horizontally above a
hard, flat surface. The height of the sensor to the surface must be equal to the
internal height of the tank. Connect the sensor temporarily as shown in the wiring
diagrams.
1 Switch on the power. The sensor will now begin to measure. The LED on the top
of the sensor will flash green.
2 Contact the plus (+) of the power supply briefly with the yellow wire.
The LED will flash red/green.
When the LED stops flashing red/green calibration has been completed.
3 Check: If the calibration has been carried out correctly, the level meter or the
control panel for dirty water (WWCP) will indicate that the tank is empty.
