  • Non-Contacting Solution for Plugged Off Flow Meters in The Oil Patch

    For years Petrobakken Energy Ltd. used inline turbine flow meters to track the flow rate of oil recycled to treaters. But with a high concentration of wax and sand in the oil, the turbine meters were quickly plugging off. The line had to be shut down at least once a day and the turbine flowmeters disassembled for cleaning. This was troublesome and expensive. Petrobakken knew there had to be a ...

  • Open Channel Flow - The use of Level sensors for open channel flow measurement

    Open Channel Flow - The use of Level sensors for open channel flow measurement Level sensors from SolidAT are implemented in Open Channel Flow applications. In these types of applications, the level sensor is installed above a special water flow structure and accurately measures level of flowing water or wastewater. The sensor then calculates flow through the structure ...

  • Portland Cement Manufacturer Upgrades Technology,Improves Operation and Reduces Costs

    One of the largest Cement factories in America was interested in reducing frequent visual emissions inspections mandated by new Portland Cement (MACT) rules in effect since June 2002. A second issue was the need to measure solids flow in the finish mill operation to determine the rejects flow rate. During a recent upgrade to the finish mill circuit, the rejects flow, which is traditionally ...

  • Comparing Capacity Expansion and Waste Minimization Options at a Chemical Manufacturing Facility

    ABSTRACTIndustrial wastewater treatment facilities that are nearing their capacity limit often have a relief option that typically is not available to municipal treatment facilities. That option is to reduce waste loads coming from the production areas by optimizing manufacturing processes so that less waste is generated per pound of product made. In making the decision between reducing waste ...

  • Two Technologies for Flow Measurement from Outside a Pipe

    Doppler and Transit Time are two very popular types of flow meter for non-invasive measurement of flow in full pipes. We tend to confuse these technologies because they are both ultrasonic and both measure flow by using sensors clamped onto the outside of a pipe. In the real world they actually work best in opposite applications. Success in your installation depends on understanding the ...
