  • Electronic Flow Control Valve (EFCV) with Pressure Compensation Capability

    A new concept for an Electronic Flow Control Valve (EFCV) with pressure compensation capability is introduced. Based on its embedded sensors and micro controller, the EFCV can provide flow control without the need of load/displacement/speed information from the power elements, like hydraulic cylinders or hydraulic motors.

  • Discussion of Flowmeter Accuracy Specifications

    Understanding the accuracy of a given flowmeter is an important field but it can also be misleading as different specifications are used to explain how accurate a flowmeter measurement actually measures. This paper discusses the different specifications and interprets the impact of them.

    Why deal with accuracy?

    The reasons for dealing with flowmeter accuracy specifications are many-folded. One important reason is from an economical point of view. The more accurate a flowmeter can measure, the more money you will save as the medium is measured with only very little inaccurately.

    Another reason is in terms of dosing, where a given amount of a medium is added. This must be done with a high level of precision and the accuracy is thus important in order to dose correctly. This is critical in certain industries such as in pharma or chemical.

    A third reason is in terms of billing purposes. By performing with good accuracy, you know exactly how much fluid flows into the process. Thereby, you are able to determine the right price of the product and thereby bill the customers correctly.

    Therefore, knowing how much that flows through your system is paramount in order to make a profitable and solid business. You need to rely on a precise measurement with good accuracy. However, good accuracy must be obtained not only in one measurement, but in all measurements independent of the time.

  • Virtualization Is a Reality

    Thin clients are performance heavyweights in industrial applications, cutting up-front and lifecycle costs while improving reliability and security. Virtualization and thin clients are two of the leading trends in computing, both in the commercial and industrial sectors. For industrial applications, virtualization and thin clients intersect when thin clients are used as a key component in virtualization strategies for process control and MES. In this white paper, you will learn about the benefits of virtualization, the interrelationship between both virtualization and thin-client technologies, why the thin-client approach is often the least expensive solution, and advantages of thin clients over PCs.
