Flow

Flow

Flow measurement covers the continuous or batch determination of volumetric or mass flow for liquids, gases, and steam. It is a foundational variable for balancing, custody transfer, dosing, and energy accounting, and it directly influences product quality, process safety, optimization, and environmental performance. Endress+Hauser positions flow as a broad portfolio specifically intended for liquids, gases, and steam applications, recognizing that these media must be measured reliably every day across industries.

A single measurement principle rarely fits every installation, so technology selection is typically driven by fluid properties, required accuracy, pressure/temperature envelope, piping constraints, and maintenance philosophy. The Endress+Hauser flow portfolio spans electromagnetic, Coriolis mass, ultrasonic, vortex, thermal mass, and differential-pressure-based flow measurement, enabling fit-for-purpose selection rather than compromise.

Benefits are realized as tighter material and energy balances, improved batch repeatability, reduced giveaway, and earlier detection of abnormal operating conditions. Multivariable measurement (where applicable) and diagnostic-rich transmitters help distinguish true process shifts from sensor or installation effects, supporting stable control and more confident decision-making. In many services, noninvasive or low-interruption approaches can reduce downtime while still providing actionable flow data.

Typical applications include water and wastewater distribution and treatment, chemical and petrochemical transfer lines, steam and condensate networks, compressed air and utility gases, and hygienic liquid service in food, beverage, and life sciences. Flow measurement is also central to blending, dosing skids, clean-in-place circuits, feedforward control in reactors, and verification of pump and heat-exchanger performance through balance calculations.

Good results depend on installation discipline and lifecycle practices: appropriate straight-run or conditioning where required, correct grounding and liner selection for conductive liquids, density/viscosity awareness for mass metering, and attention to wet-gas or two-phase risks. Protocol and integration choices should align with the control architecture and asset strategies, with calibration/verification plans matched to criticality, regulatory expectations, and measurement uncertainty targets.
