10.11 Ullage/Interface verification
The sensitivity of the instrument in ullage /
interface cannot be adjusted. Both ullage and
interface levels are set at the factory.
Checking ullage and interface level detection
The test liquid should be the one to be gauged.
Fill in a container with appropriate liquid.
Switch on the unit. The buzzer shall beep every 2
sec.
If the liquid is conductive (alcohol, water, ...)
- Check
the
ullage
by immersing the ultrasonic
gap sensor but not the electrodes (position A);
The buzzer shall beep continuously.
- Check the
interface
by immersing the
interface electrodes (position B). The buzzer
shall beep intermittently.
If the liquid is non conductive (gasoline, oil, ...)
- Check the
ullage
by immersing the sensor
(position B); The buzzer shall beep
continuously.
- Check the interface by immersing the sensor
(position B) in water. The buzzer shall beep
intermittently.
