FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?
FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?

Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

  • Continuous Analyzer Integrated Data Validation
    Continuous Analyzer Integrated Data Validation

    Continuous analyzers are an integral part of the process to maintain quality, ensure compliance, and protect public health. Therefore it is imperative to ensure the analyzers are functioning properly and provide accurate and reliable data. This requires validation of the data provided by the analyzer on a routine basis. In addition some continuous analyzers incorporate internal data validation capabilities to inform the end user the reliability of the data provided by the analyzer. This paper discusses integrated data validation and how they may be integrated into SCADA systems.

Mazzei Degas Separators Selected For Wichita Aquifer Project Mazzei Degas Separators Selected For Wichita Aquifer Project

A key component of the water supply plan for the City of Wichita, Kansas, was recharging the large aquifer that lies under the region with water from the Little Arkansas River. The river basin contains substantial farming operations which, during rain events, spike the river water with the commonly used herbicide Atrazine. Atrazine concentrations in the river frequently rose forcing the city to shutdown the bank filtration system. Advanced oxidation process (AOP) was selected to remove the herbicide. The AOP reactor’s design limited the amount of hydraulic backpressure it could tolerate. Consequently, Mazzei was challenged by the project’s design team to remove the entrained gas bubbles that remained from the prior oxidation treatment at a “not to exceed” hydrostatic backpressure of 19 feet.
