Endress+Hauser”s Deltatop differential-pressure (DP) flowmeter is designed for measuring gas, liquid and steam in 1/2″ to 24-inch pipes. Deltatop is a complete flow monitoring solution, including an averaging pitot tube. Deltatop features precision-machined orifice plate primary devices complete with flanged unions, manifold and transmitter — designed specifically for applications in accordance with ASME B16.36. The primary elements are designed to safely and accurately measure flow on liquid, gas or steam. The flow solutions are available in class 300# to 2400# flanges. Flow accuracy is achieved through the development of a theoretical model of flow coefficients that have been proven through empirical test data and verified by independent laboratories. The bullet-shaped solid-piece construction and the location of low-pressure ports makes the flow solution clog-free and precise with extremely impressive signal-to-noise ratio, enabling stable flow readings across the entire measurement range.
