A flexible scintillation-type level detector (), in which the scintillator () is made from a flexible tube () substantially filled with a liquid scintillating material () to provide flexibility in at least two, and preferably three, dimensions. At least one end () is aligned for operable connection to a photodetector (). Outer surfaces of the flexible tube () may be covered with an inwardly-facing light reflective material () and/or light-excluding material or flexible armored casing(). The scintillator () may include a variable-volume expansion chamber () to compensate for thermal expansion and contraction of the liquid scintillator material ().

A detector assembly includes an elongate structure and a scintillation detector. The elongate structure defines a detector cavity having an axial dimension extending along a longitudinal axis. The scintillation detector is disposed at least partially within the detector cavity. The detector system can also include a cabinet which can be coupled with an end of the elongate structure, and which can define a cabinet cavity for retaining a junction board, a display screen, a microprocessor unit, and/or other components. The detector assembly can have an explosion-proof rating. A detector system including the detector assembly and a detector unit is also provided, such as for use in applications requiring an explosion-proof rating.

Shown is a flexible scintillator, or scintillation-type level detector, in which the scintillator is made from a plurality of elongated, relatively thin layers of plastic scintillator material stacked in close proximity to one another in a slidable relationship to provide flexibility in at least two dimensions. The layers of at least one end are aligned for operable connection to a photodetector. Optionally, an anti-friction material, such as PTFE, may be placed between layers of the plastic scintillator material. Edge and outer face surfaces of the layers of the scintillator material may be covered with an inwardly facing light reflective material and/or light-excluding material.
