        Level Switch

        Level switch applications are found in all types of production, including the food industry, for monitoring one or more high/low levels on fluids or bulk material. This is applicable on all kinds of vessels such as

        • Storage tanks
        • Hot product bunkers
        • Stirrer vessels cyclones
        • Slices
        • Feeder chutes etc.

        Measuring Principle
        The level switch system is based on the physical law of the attenuation of gamma radiation as it passes through matter. In case, there is product in between the source and the corresponding detector, the detected radiation decreases by a considerable extend. This effect corresponds to the product's presence or absence and therewith it is signalised whether the surveyed level is reached or not. The measurement is independent of high temperature, high pressure or vacuum, volatile & biohazard material, corrosive material, agitators, baffles, coils, build up on vessel walls, physical and chemical properties of the product and the process.

        Advantages
        • Contact less measurement
        • External mounting without modification of the existing vessel
        • Lowest source activity
        • Decay compensation
        • Independent from chemical composition and most physical properties

        Continuous Level Measurement

        The external mounting and the non-intrusive arrangement of a continuous level measurement are the outstanding advantages that determine it for various applications like:

        • High- and low-pressure reactors
        • Agitated vessels
        • Bunkers
        • Autoclaves
        • Hot material containers, etc.

        Measuring Principle

        The nucleonic continuous level measurement operates according to the physical law of attenuation of gamma radiation, while it is passing through the matter. 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 transferred 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. The measurement is independent of high temperature, high pressure or vacuum, volatile and biohazard material, corrosive material, agitators, baffles, coils, build up on vessel walls, physical and chemical properties of the product and the process.

        Advantages
        • Non-contact, continuous measurement of the filling level

      Density Measurement

      The contactless and continuous measurement of the density of liquids or bulk material is requested in even more than the following applications:

      • Concentration measurement of acid, alkali, saline solution and suspension
      • Crystallisation and polymerisation monitoring
      • Determination of the solid matter content in slurries, in flue gas desulphurisation suspensions, in aluminium production and in mining
      • Measurement of the bulk density in washing powder and clinker

      Measuring Principle
      The density measurement operates according to the physical law of attenuation of gamma radiation, which is dependent from the radiation energy, the measuring path length and the density of the irradiated product. Through keeping the energy constant and since the measurement takes place in a pipeline, so the measuring path’s length is also constant, the attenuation is only dependent from the applicable density of the measured product. The radiation intensity, received from a sealed and shielded source is measured by a most sensitive scintillation detector and this measuring signal is then converted to a density or concentration measurement signal by the corresponding evaluation unit. Dependent from the desired measuring range and accuracy and the products specification, the ideal irradiation angle is selected or a measuring path is used. Measurement is independent of colour, viscosity, conductivity and most chemical properties of the product.

      Advantages
      • Non-contact, continuous measurement of density or concentration
      • Adaptable to all pipelines from 25 to 1000 mm
      • Most simple installation on existing pipelines

      Bulk Flow Measurement

      The contact less measurement and the lack of moving parts, allow a precise determination of the mass flow without any wear to the systems components. This outstanding advantage is applicable on various mechanical conveying systems like:

      • Belt conveyors
      • Screw conveyors
      • Troughed chain conveyors
      • Steel plate conveyors
      • Bucket conveyors
      • Free fall in chutes or pipes

      Measuring Principle
      The intensity of radiation, coming from a specially designed radiation source, is measured by a scintillation counter after it has passed the material and the conveying system. From the resulting measuring signal, which is dependent from the loading on the conveyor system and the product speed, the evaluation unit calculates the mass flow rate. The measurement is independent of high temperature, high pressure or vacuum, volatile and biohazard material, corrosive material.

      Advantages
      • Contact less measurement
      • External mounting without modification of the existing conveyor system
      • Lowest source activity

      Neutron Moisture Measurement

      For the continuous determination of moisture in bulk solids, the neutron moisture measurement gives a representative moisture signal on applications like:

      • Sand moisture
      • Coke moisture
      • Sinter moisture
      • Calcareous limestone

      No matter, what the temperature, pressure, pH value and colour of the material is.

      Measuring Principle
      The neutron moisture measurement is based on the principle that fast neutrons are slowed down (or moderated) through their collision with hydrogen nuclei. Thus, a cloud of slow neutrons is created around a source of fast neutrons coming from an americium/beryllium source, while the concentration of slow or thermal neutrons depends only on the hydrogen content in the measuring volume. The Nuclear measurement will not change the products being measured. The measurement is independent of

      • High temperature
      • High pressure or vacuum
      • Volatile and biohazard material
      • Corrosive material
      • pH value and colour of the product

      Advantages
      • Continuous measurement of moisture content
      • Detection of all water molecules, irrespective of their physical or chemical bond
      • Simple installation in or on existing tanks, vessels or conveyors
      • Large measuring volume, ensuring representative moisture determination
      • Lowest source activity due to the use of most sensitive He-3 counter
      • On line measurement
      • No moving parts
      • Reliable technology
      • Low maintenance
      • Easy to calibrate

        Concentration Measurement via Microwaves

        The Berthold Technologies LB 566 Micro-Fluid is a continuous, on-line concentration-measuring gauge that determines the water-content or dry mass of suspensions, solutions, or pastes. It is installed directly into existing pipe systems via a stainless ‘flow cell’. All wetted parts are PTFE lined. The Micro-Fluid LB 566 is suitable for numerous applications in the food industry where the water-content of pastes, milk products or vegetable oils is an important process variable for consistent manufacturing and quality control purposes. Similarly, the Micro-Fluid LB 566 concentration monitor may be employed on a wide range of industrial processes.

        Measuring Principle
        Wave-guides fitted diametrically opposite to each other on the ‘flow cell’, facilitate the transmission of microwaves through a product flowing through the pipe (-see diagram). The microwaves are reduced in intensity (attenuation) as well as in propagation speed (phase shift) by the product, subject to the dielectric properties of the product. The strong dielectric characteristic of free water molecules relative to other liquids or dry matter allows a determination of the water content of the product by measuring the attenuation and/or phase shift of the microwaves. Based on this measurement principle, the micro-fluid LB 566 supplies a process signal proportional to the concentration / water-content / dry mass of the product measured.

        Measuring Arrangement
        The ‘flow cell’ [1] is preferably installed in a vertical pipe with upward flow direction and slight overpressure. The process connection is via flange or optionally screw neck or tri-clover fitting. The evaluation unit [2] is installed immediately adjacent to the ‘flow cell’. The HF-measuring cables [3] connect the evaluation unit and the ‘flow cell’. The HF-reference cable [4] is a loop circuit, which is used to compensate for changes, like environmental temperature changes, that may effect the signal in the measuring cable, and hence the quality of measurement.

        Advantages
        • Representative measurement as a result of the microwaves being transmitted through the entire cross section of the ‘flow cell’
        • Reliable measurement signal due to continual software plausibility checks of process signal parameters and compensation of varying environmental temperature
        • Continuous, on-line measurement
        • ‘Flow cell’ available in different pipe diameters
        • Low maintenance
        • Uncomplicated calibration
        • Trouble-free installation on existing pipelines
        • No moving parts or parts protruding into the flow stream.
