Spirax Sarco”s M410line of orifice plate flowmeters measures both density-compensated andnon-density-compensated flow of steam, liquids and most gases. Themeters reduce maintenance costs by eliminating: a. moving parts or holes that can clog; b. internalgaskets that can fail; and c. the need for bypass piping installation.The units can also be combined with temperature/pressuretransmitters and flow computers to create a custom meteringpackage for specific applications. The meters provide a 4-to-1turndown with an accuracy of +/-3 percent of rate and a repeatabilityof +/-0.3 percent.
