| In
many installation there is no accurate measurement of flow, or the
pumps may be valved back slightly to control the water flowrate. As
soon as you start restricting the flow from a pump you are wasting energy, and the amount
of energy wasted can be considerable. For example, if we take a
situation in which a pump is valved back to 90% of its water flow, the
energy savings relate to an inverse cub law. For example a 10%
reduction in flow, equates with an energy saving as follows;
100 - (0.9 x 0.9 x 0.9 x 100) = 27.1% energy saving. ( 0.9 = 10% reduction in flow, 0.8 = 20% reduction and so on) If you have 15 kw pump and can save 27% of energy, this equates with 4 kw of energy, at 0.07 pounds UK per kw, this equates with a saving of 2452 pounds UK per year. This will cover the cost of the inverter variable speed drive and the flow monitor, there will be control panel and installation costs, however in general you will be able to achieve a return in capital in 2 to 3 years. The Magnetic Flow meter is a flange mounted flow monitor for the measurement of a wide range of water types, we work in partnership with Siemens for the supply and installation of magflow meters. for a wide range of applications in industry, especially when pressure filtration systems using AFM or sand are employed. |

| remote wall mount box for Mag6000 | Mag 6000 transmitter, 230v 50 hz, may be mounted on a wall or the electrode | Standard electrode approved for drinking water | Electrode shown with transmitter mounted on top | Panel mounted Mag 6000 transmitter is also available |
| A flow monitor
comprises of a electrode and a transmitter, you have an option of mounting
the transmitter directly on the electrode, or remotely if you use the wall
mount kit, alternatively a panel mount transmitter may be used. The head can be mounted remote from the flanged pipe fitting, or it can sit on top of the pipe as shown in the photograph above. If remote displays or logging are required, the standard unit has a two wire 4 to 20 mamp analogue output. The analogue out can also be connected to our pump inverters to vary the speed of the pump and hence water flowrate. With filtration systems it is very important to achieve the correct flowrate, with the feed back control system you just dialup the water flow required and the system will give you a very accurate flow without the need to valve back pumps. This can save a huge amount of energy, and also allows you to operate the system at the correct water flow for both the run phase an back-wash mode. The enclosure is rated at IP67 for out-door use, but it can be upgraded if required to underwater IP68 status, by using the potting kit. The electrode is contained in the flanged fitting and is manufactured with stainless steel hastalloy electrode in an EPDM liner. These are probably the best flow monitors suitable for a wide range of applications to give many years of trouble free operation. A full range of flanged pipe sizes are available from DN6 to DN2000 and flowrates from 0.025 cubic metres per hour to 113,000 cubic metres per hour are available. Installation notes. The Flow meter should be on a horizontal section of pipe, with 5 times flange diameter of pipework before and 3 time flange diameter after the flow meter. For example, a DN100 flow meter must have 0.5m of pipework with no bends or obstructions before the flow meter and 300mm after the flow meter. This insure a smooth non turbulent flow through the flow meter. |
