G i l f l o I L V A Gilflo ILVA Flowmeters for steam, liquids and gases Gilflo ILVA Flowmeters will help you implement cost reduction by accurately metering the energy you use. This can lead to improved profitability and a reduction in your carbon footprint. The Spirax Sarco Gilflo ILVA Flowmeter is perfectly suited for use with most industrial fluids including steam, gases and liquids. The benefits of flowmetering Of all the costs your company can control, your energy bill is one of the largest. With the high cost of fuel, it is increasingly important to accurately meter the energy you consume - because the better you understand how and where you use your energy, the easier it is to manage and effectively control. Spirax Sarco can offer you a range of flowmetering technologies to suit every application so you always have the correct solution for your plant.
spiraxsarco.com The benefit of high turndown The benefit of compact installation Due to its profiled cone and spring, the Gilflo ILVA is able to measure from full flow down to very low flowrates with a turndown of 100:1. This means that the ILVA continues to measure where other technologies with a lower turndown cannot. With the ILVA, off peak and low demand flow is metered just as accurately as higher flowrates. This gives the benefit that the true flow measurement, and therefore costs are known. The Gilflo ILVA profiles the flow, which allows installation when only very short upstream and downstream pipe lengths are available. It achieves this by flattening the profile of the flow stream as it enters and leaves the flowmeter (see diagram below). Turndown ratio comparison of flow technologies on saturated steam Measuring from minimum to maximum flowrates (turndown). Typically 100:1 continuous Gilfo ILVA The compact wafer design of the Gilflo ILVA flowmeter also means that its installed length is much shorter than almost any other technology. It can be installed close to pipe bends, valves or other components that would prevent other types of flowmeter being fitted, as shown in the diagram below.

spiraxsarco.com Self-alignment tabs for guaranteed correct installation Over-range stop prevents damage from surges or excessive flows Highly stable precision alloy spring operates up to 400 C without loss of performance Precision cone profiles the flow giving unrivalled 100:1 turndown, for more accurate flow measurement Wafer design is lighter, quicker and easier to install and is therefore more cost effective
G i l f l o I L V A DN250 and DN300 Gilflo ILVA Flowmeters now come with a compact stem The wafer design of Spirax Sarco s Gilflo ILVA Flowmeter requires less space when ordered with the compact stem. The compact stem directly connects the Gilflo ILVA and the DP transmitter which saves on both installation time and cost when compared to installations using impulse lines. This reduces plant downtime, lowering costs and impacting less on productivity. Compact Stem replaces traditional impulse lines reducing installation complexity Simple bolt-together assembly reduces installation time and cost Differential pressure and static pressure measured to supply mass flow without need for additional instrumentation The Gilfo ILVA is just one of a comprehensive range of products that have been developed by Spirax Sarco to meet the needs of their customers.
