Oil on water monitoring with model FLUCOmat: The device is used for continuous monitoring of water surfaces. It detects floating oil films with extreme high sensitivity.

The Oil in Water Measuring System Model FLUORImat is used for continuous monitoring of water / condensate. It detects any oil contamination in water with high sensitivity. Fluorescence principle: Organic substances such as fats and oils are fluorescent. When they are irradiated with UV light, they begin to glow. Electronically excited molecules release energy and return to their ground state. This process is known as fluorescence. The emitted radiation has a longer wavelength than the radiation used for excitation.

Turbidity describes the characteristic of a transparent product, to scatter or absorb light. A focused light beam will be attenuated and scattered in hazy products, so that this product can become practically opaque in bigger layers. Turbidity is caused by particles in transparent products. A particle is defined as something with a different refractive index as the carrier liquid. Some examples of particles are minerals, yeast cells, metals, oil drops in water, milk in water, gas bubbles and aerosoles.

Most turbidity, concentration or colour transmitters are capable of handling only one probe connected to them. In situations where a number of sensors are required, the cost of multiple transmitters can be high. The Messenger addresses this by allowing up to 4 inputs into one transmitter. All inputs are discrete, allowing control of the sensor and transmission of data on a completely individual basis. One transmitter controlling up to 4 detector signals keeps the cost per data point very low. Also, the Messenger is available in three different versions. Version 1: Panel PC with Touch screen; version 2: 4 line LCD- display; or version 3: with no display. This allows for a cost saving configuration related to your specific application.

The turbidity sensor Model MoniTurb-F uses the principle of 12° forward scattered light to detect suspended particles in liquids. The transmitter model Messenger is required to use this sensor. The system has been designed for continuous operation with long life time. A ratio measurement of direct- / scatter light assure highly reliable and repeatable measurement results. Inaccuracies caused by product colour, lamp ageing or window coating will be compensated. The forward scatter measuring results are nearly independent of particle size and will correlate to product concentration. Calibration can be done in multiple ranges and measurement units like EBC, ppm, mg/l, etc.. The sensors can be installed into almost any type of pipe. Process connection, pressure, temperature, gasket material, etc will be application specific. Optional cleaning jets will allow a cleaning of the sapphire windows in determined intervals.

The laboratory turbidimeter model TurbiLab-FS uses the principles of 12° forward- and 90° side scattered light, to detect suspended particles in liquids. The instrument detects the turbidity of the liquid only, product- or bottle colour will not affect the measuring results The measurement will be done directly in a bottle or in a cuvette. The bottle respectively cuvette, turns around its own axis during the measurement cycle. The water inside of the measurement chamber equalizes scratches and unevennesses of the bottles. The measurement result is calculated from average of 200 measurements per bottle rotation.

The probe model AP2 uses the principle of near infrared light absorption to detect turbidity in liquids. The basic version of the probe allows for process temperatures of max. 45°C. The optional high temperature version allows for 105°C permanent temperature. The transmitter model Messenger or CCAb is required to use the AP2 probe. The system has been designed for continuous operation with long life time. The 19mm probe design allows insertion to laboratory fermentation tanks. Different flanges, TH- Varivent adaption, Tri Clover adaption or ball valve installation are available to allow application specific insertion of the probe in nearly any process pipe.

The sensor model LAS uses the principle of light absorption to detect dissolved or suspended particles in liquids. The transmitter model Messenger or CCAb is required to use this sensor. The system has been designed for continuous operation with long life time. The use of metal melted measurement windows without any additional gaskets guarantee for a perfect hygienic design. The installation by using TH-Varivent plates offers a cost saving process installation via standardized flow cells. The implemented calibration filters allow the calibration of the system without using liquid calibration standards. The absorption caused by turbidity will be detected at a wavelength of 850nm. Therefore the measurement results are not affected by product colour.

The sensor model TURBImat-A uses the principle of NIR- light absorption to detect dissolved or suspended particles in liquids. The transmitters model Messenger or CCAb are required to use this sensor. The system has been designed for continuous operation with long life time. Calibration can be done in multiple ranges and measurement units like FTU, ppm, etc.. The sensor detects the absorption of infra red light. Therefore the measurement results are not affected by product colour. Ranges of 0-50FTU up to 0-20000FTU are possible, due to the availability of multiple optical path lengths (2mm up to 60mm). The sapphire windows of the sensor are accessible via GF- fittings, this allows a very fast window cleaning if required.

The sensor model UVS-1 is used to detect UV- absorbing substances in liquids at wavelength of 254nm or 280nm. Other wavelengths are available on request (240 – 880nm). The lifetime of the LED- light sources is between 2 and 5 years (depending by wave length and application).
