Differential pressure flow
Nozzle (ISA1932) for international standardized differential pressure flowmeter system
The Deltatop DN61S is part of the universal differential pressure flowmeter systems with primary elements as Venturi tubes, nozzles, orifice plates and Deltabar dp transmitters. As with Venturi tubes, a wide variety of nozzles are available. These nozzles can be standardized or developed in line with manufacturers specifications. Practically all versions can be provided by Endress+Hauser. A nozzle consists of a convergent section with a rounded profile and a cylindrical throat.
Customized or application-specific flowmeter systems based on the dp method for special applications, such as: Low pressure loss, high abrasion resistance, calibrated meter runs, extended nominal diameter range, controlled pressure reduction
Optimized for minimum pressure loss, maximum accuracy or maximum turndown
Measuring range of the Deltabar differential pressure transmitter adjusted on delivery
Application of international standards (e.g. ISO 5167)
Robust design and no moving parts
Field of application
Flow measurement of gases, steam and liquids.
