Reliable, cost-effective dp flow measurement

Endress+Hauser’s AptiFlow averaging pitot tube is the cost-effective choice for measuring flow
Now the company is manufacturing a range of AptiFlows with two measuring probes for use in dual redundancy. Designed for use in the petrochemical industry, but suitable for a range of applications, the dual redundancy option offers maximum reliability. These instruments can also be designed to meet your unique specification.

The AptiFlow has integral, three-valve manifold heads that allow Endress+Hauser’s PMD series of low range differential pressure transmitters to be direct mounted. This ensures the system is cost-effective and dependable as no extra parts are needed and potential areas of leakage are considerably reduced. There’s also no restriction on the size of the pipeline. What’s more, as it doesn’t required periodic recalibration, maintenance is often as simple as carrying out a regular inspection and installing a replacement when needed.
Using differential pressure to measure flow has become more popular in recent years, as AptiFlow designer Kenny McGouran explains: “Modern dp transmitters can accurately measure very low differential pressures and boast a turndown ratio as high as 1000:1 with little or no effect on accuracy. This makes flow measurement using the AptiFlow range a very attractive proposition.”
