Manual

Standpipe:
l Product speed: very fast filling and emptying
l Vessel:
- Vent hole
- Joins like flanges, weld joints
- Shifting of the running time in the tube
l Process/measurement conditions:
- Condensation
- Buildup
Bypass:
l Product speed:
- Fast up to slow filling with short up to long bypass tube
possible
- Often the level is hold via a control facility
l Vessel:
- Lateral outlets and inlets
- Joins like flanges, weld joints
- Shifting of the running time in the tube
l Process/measurement conditions:
- Condensation
- Buildup
- Separation of oil and water possible
- Overfilling into the antenna possible
Plastic tank:
l Vessel:
- Measurement fix mounted or integrated
- Measurement depending on the application through the vessel
top
- With empty vessel, the measurement can be carried out
through the bottom
l Process/measurement conditions:
- Condensation on the plastic ceiling
- In outside facilities water and snow on the vessel top possible
Transportable plastic tank:
l Vessel:
- Material and thickness different
- Measurement through the vessel top
l Process/measurement conditions:
- Measured value jump with vessel change
Open water (gauge measurement):
l Gauge rate of change: slow gauge change
l Process/measurement conditions:
- Distance sensor to water surface to big
- Extreme damping of output signal due to wave generation
