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.01/21/2013

This White Paper explains:
- What the 3S CoDeSys vulnerabilities are and what an attacker can do with them
- How to find out what control/SCADA devices are affected
- The risks and potential consequences to SCADA and control systems
- The compensating controls that will help block known attack vectors
A number of security vulnerabilities in the CoDeSys Control Runtime System were disclosed in January 2012. In October 2012, fully functional attack tools were also released to the general public.
While CoDeSys is not widely known in the SCADA and ICS field, its product is embedded in many popular PLCs and industrial controllers. Many vendors are potentially vulnerable, and include devices used in all sectors of manufacturing and infrastructure. As a result, there is a risk that criminals or political groups may attempt to exploit them for either financial or ideological gain.
This White Paper summarizes the currently known facts about these vulnerabilities and associated attack tools. It also provides guidance regarding a number of mitigations and compensating controls that operators of SCADA and ICS systems can take to protect critical operations.12/26/2012
Water conservation is becoming a major focal point, both in the public and private sector whether it is due to cost of water, availability of water, or environmental concerns.12/22/2012
Wastewater treatment facilities are generally installed for one purpose - to clean up dirty water so that clean water can be discharged back into the environment. Nearly all municipal treatment plants rely on biological processes for wastewater treatment whereby bacteria and other microorganisms, frequently called 'bugs,' do this job of cleaning up the water.12/20/2012
This white paper provides insight into the evolution of the modern SCADA system and looks to the very near future by discussing such timely topics as:
- Improving system efficiency and security
- Managing field data and
- Open standards
Some 66% of the process control systems now in use globally were installed before publication of today's commonly used safety standards, IEC 61508 and IEC 61511/ISA 84. Here's how to tell if you safety systems are up to snuff.12/13/2012
