Continuous Level Measurement

|
|
The external mounting and the non intrusive arrangement of a continuous level measurement are some of the outstanding advantages, that determine it for various applications like:
- high- and low-pressure reactors
- agitated vessels
- bunkers
- autoclaves
- hot material containers, etc.
No matter, what the physical- and chemical properties of the measured product are nor what the shape of the vessel is.
Measuring Principle
The continuous level measurement operates according to the physical law of attenuation of gamma radiation, while it is passing through matter. Practically, the product to be measured is shielding the radiation coming from a radioactive source and according to the height of the product, more or less of the original radiation is reaching the detector. This measuring signal is then transfered to an output signal which directly correlates to the actual level of the product.
Depending on the measuring arrangement, either a rod shaped detector or one of minor size is selected, both using the most efficient scintillation principle, which allows the use of lowest possible source activities. Under extraordinary conditions, even the use of a rod shaped detector in combination with a source of the same length is possible and will give the most accurate level reading.
Nuclear measurement will not change the products being measured!
The measurement is independent of:
- High temperature
- High pressure or vacuum
- Volatile & biohazard material
- Corrosive material
- Agitators, baffles, coils etc.
- Build up on vessel walls
- Physical and chemical properties of the product and the process
Advantages:
- Non-contact, continuous measurement of the filling level
- Adaptable to all vessel shapes
- Level- or volume-proportional arrangement
- Measuring range up to more than 10 m
- Lowest source activity automatic decay compensation
- Choice between Co-60 or Cs-137 as radiation source
- On line measurement
- No moving parts
- Reliable technology
- Low maintenance
- Easy to calibrate
