New radiometric density system

June 2018 Analytical Instrumentation & Environmental Monitoring

DuoSeries LB 475 is the new radiometric density system from Berthold, especially designed for the cementing and hydraulic fracturing industry.

The system stands out through excellent all-round performance with high accuracy and repeatability. Depending on customer needs, the transmitter output can be configured for units of specific gravity (SGU), ‘pounds per gallon’ (PPG), or a calculated ‘pounds proppant added’ (PPA). The DuoSeries easily connects to the FracSENS LB 6770 detector and links directly to the customer’s control system. No calibration or complex mathematics is required in the data system. The density gauge is used to translate the measured count rate into the specified output values either in low or in high pressure applications.

The density transmitter is state-of-the-art with a robust 3,5” TFT touch panel, powerful Dual Core CPU, and a diverse range of interfaces. Operators benefit from the new simplified HMI where calibration is kept as simple as possible. Only two points – a low and a high density, e.g. air and water – have to be acquired by the customer. Advanced self-diagnostics and monitoring features ensure safe functioning of the system. Operators also benefit from the new service functionalities like data-logging, which can be accessed either remotely through Ethernet connection or through the USB port on the front panel of the system.

Berthold Technologies’ radiometric instruments are used in the oil production industry worldwide to control and monitor level, interface level, emulsion layers and density. The measurement systems are installed offshore and onshore on drilling rigs, production platforms, FPSO, hydraulic fracturing, in oil terminals as well as in the Canadian oil sands, providing highly accurate and reliable process information for optimised process control. All products are internationally renowned for their high quality and reliability. The quality management system is certified according to DIN EN ISO 9001:2008, ISO 14001:2004, BS OHSAS 18001:2007 and KTA 1401.
