Anton Paar produces high-quality process sensors and laboratory instruments for the analysis of liquids. Its instruments are known for having the highest precision and being extremely robust. They are successfully used worldwide in industry and research. Anton Paar's solutions for the petrochemical industry include online density sensors, sound velocity sensors and viscometers.
Continuous monitoring of density, concentration, API gravity and viscosity
Anton Paar's online instrumentation ensures the continuous control of density, product quality and product specifications within tight tolerance limits. A variety of wetted parts, materials and process connections are available to suit each application.
A team of application specialists provides expert advice based on long experience, and assists in solving new application tasks.
Online density sensors for petroleum products
Anton Paar's L-Dens 427 series of density sensors combines high accuracy in a compact design. They continuously measure density, concentration and API gravity to optimise production processes and ensure a consistently high-quality product. The small and compact design allows for easy integration into measuring stations, for example, for mass flow rate measurement. L-Dens 427 is used at refineries, ethanol production plants, and in the storage, transport and delivery of fuels and ethanol products. It measures all low-viscosity, non-corrosive fluids such as the intermediate and end products of refineries, crude oil, LPG, lubricants, ethanol and biodiesel.
The L-Dens 427 series provides a hazardous area rating according to ATEX and FM, process connection and communication signal to suit your plant.
Online density sensors for aggressive liquids
Anton Paar's DPRn series of density sensors are used for the measurement of aggressive liquids, liquids with high temperatures or whenever the highest accuracy is needed. They continuously measure density, concentration and API gravity to optimise production processes and ensure a consistently high quality of product.
DPRn is used at refineries and in the petrochemical and chemical industries. It measures all fluids such as products of refineries, acids, caustics and many more chemicals. Intrinsically safe versions are available for use in hazardous areas as well as a model for high-temperature measurements.
Sound velocity sensors
Anton Paar's SPRn series of sound velocity sensors are used for concentration measurement and phase separations. They continuously measure the sound velocity and calculate the concentration to optimise production processes and ensure a consistently high-quality product.
SPRn is used in the petrochemical and chemical industries. It measures the concentration of acids, caustics and many other liquids. Another application is the phase separation of crude oil and brine or the monitoring of a splitter.
The measurement is direct in the pipework or tank so no bypass is required. Intrinsically safe versions are available for use in hazardous areas.
L-Vis 510 is an inline viscometer from Anton Paar, which uses a completely new measuring principle. It is immersed directly in the production liquid in the pipework or tank so no bypass is required.
L-Vis 510 continuously measures and displays the viscosity and temperature, allowing 24hr monitoring of lubricants, suspensions and many more process liquids. Drops in pressure or flow rate do not affect the measurement results.
Portable intrinsically safe density meters
Anton Paar also provides portable intrinsically safe density meters for on-site API gravity determination and laboratory density meters, which measure samples with high viscosity and/or high melting point or softening range, such as bitumen and pitch. It also provides a benchtop viscometer, which determines the dynamic and kinematic viscosity and density according to ASTM D7042.
