What Are The Advantages And Disadvantages Between A Mechanical Flow Meter And A Magnetic Flow Meter? (Part Two Of Two)
2016-02-16 15:02:20| chemicalonline Downloads
In Part One of this series, we started the discussion of magnetic flow meters versus mechanical flow meters. We talked about the differences in construction and how a meter with moving parts can affect the total cost of ownership through maintenance and reduced performance. In this article, I want to address some of the mounting, accuracy and process considerations of mechanical meters compared to mag meters. Let’s look at process considerations first. Mag meters are suitable for the measurement of conductive liquids. What do we consider a conductive liquid? For conductive liquids, we are specifically looking at liquids with conductivity of 5 microsiemen/cm or greater as suitable. Mag meters are also suitable for liquids with either suspended solids or slurries. This makes them ideal for water-based products and most acids and bases as well as slurries like the ones you find in wastewater treatment, mining, and pulp and paper applications. Mag meters are also very flexible when it comes to viscosity, but they are not suited for hydrocarbon-based products, gases or steam. With hydrocarbon-based products, there is just not enough conductivity present for a mag meter to work.

There has been a lot of discussion on using mechanical meters versus magnetic meters for the measurement of conductive liquid. While both flow meters offer benefits, is one more efficient and effective for you to use? The purchasing price is certainly a consideration, but it’s not the only thing that you should consider when looking at upgrading your system. What Are The Differences Between The Two Flow Meters? The primary difference between a mechanical meter and a magnetic meter is that a mechanical meter has moving parts and a mag meter doesn’t. Typical examples of mechanical meters are target meters, where liquid hits a spring loaded plate and the amount of movement of that plate relates to velocity, and turbine meters, where liquid flowing over a set of angled blades causes those blades to rotate and that velocity is used to determine flow rate. Another example would be a positive displacement (PD) or oval gear meter where a set amount of material moves through chambers and the amount of material that moves through these chambers as they rotate is counted and converted to flow rates. There are other mechanical designs, but you get the picture. A mag meter works by having a conductive liquid flow through a lined flow tube and of the flow passing through a magnetic field generated as part of the flow tube design causes a voltage to be created. This voltage increases or decreases based on velocity. So, as long as the material meets the minimum conductivity level, there are no moving parts (mechanical motion) in the flow meter itself required to measure the flow rate through the meter. Okay, now that we have a basic concept of each flow meter, what are the advantages and disadvantages?
Liberty Global targets acceleration in cash flow growth
2016-02-16 08:44:00| Telecompaper Headlines
(Telecompaper) Cable operator Liberty Global reported a strong finish to 2015, with net additions of 344,000 revenue-generating units in the fourth quarter. Revenues were up 4 percent and operating cash flow 6 percent higher on an organic basis in Q4, led by Virgin Media in the UK and Unitymedia in Germany. CEO Mike Fries said the company saw a stronger second half of 2015 than the first six months, and Liberty Global expects the growth to improve further in 2016. The growth will be driven by the 'Liberty 3.0' plan, to enhance revenue and operating cash flow by focusing on B2B, mobile, network expansion and cost controls over the next three years. The company expects to deliver 5-7 percent organic OCF growth in Europe in 2016, excluding the Dutch business Ziggo, which is being merged with Vodafone Netherlands, and the recently acquired Belgian mobile operator Base. Over the next three years, operating cash flow is expected to grow at an organic rate of 7-9 percent.
