Differential Pressure Flowmeter

Flexible DP Flow Solutions for Demanding Industrial Applications

Built around orifice plate, Venturi, and V-cone technologies, differential pressure flowmeters remain the trusted choice for steam, gas, and demanding liquid service. It support accurate flow measurement across power, chemical, oil and gas, and utility systems with flexible design for different process conditions.

Technology Selection

Is Differential Pressure Flowmeter Right for Your Application?

No other flow technology operates reliably across gas, liquid, and steam at extreme temperature and pressure — but the tradeoffs in accuracy and turndown must be weighed against your process demands.

Differential Pressure Flowmeter Excels Here

Your process runs in at extreme temperature or pressure

Your medium is steam, gas, or process liquid

Your process fluid is dirty, wet, or two-phase

Your pipeline is closed, full-bore, and pressurized

Your application accepts some permanent pressure loss

Your pipeline exceeds DN300 and inline full-bore meter costs are prohibitive

Consider Alternatives Instead

Your process cannot sustain any permanent pressure loss

Your line has severely disturbed or unstable flow profiles

Your fluid is highly viscous, solids-laden, and prone to scaling

Your fluid contains heavy aeration or flashing liquid

Your flow rate varies widely

Your process demands higher available accuracy

Performance Advantages

Key Process Benefits of Differential Pressure Flow Measurement

Differential pressure flowmeters are widely used because they perform across complex media types and severe process conditions with dependable stability. Their mature technology, flexible primary-element designs, and broad industrial acceptance make them a practical choice for long-term plant operation.

Extreme Pressure Tolerance

Engineered to operate flawlessly in high-pressure environments up to 42MPa, ensuring safety and data integrity for critical gas and steam pipelines.

Fluid-Independent Accuracy

Measurement accuracy remains consistent even when temperature, viscosity, density, or pressure fluctuate during operation, no recalibration.

Extreme Thermal Resilience

Engineered to perform in temperatures exceeding 850°C, offering superior thermal stability for superheated steam and high-heat process gas applications.

Configurable Flow Range

Offers flexible sizing and throttling geometry to perfectly match your specific pipe diameter and required flow capacity for precision output.

Universal Fluid Capability

Eliminate the costs of replacing sensor or impeller. The simple, non-moving structure ensures a "set-and-forget" installation that drastically lowers lifecycle expenses.

Low-Maintenance Design

With no moving parts in the primary element, it reduces wear-related failures and helps lower routine maintenance over long operating cycles

Find Your Installation Match

Accurate Flow Measurement Starts with an Accurate Specification

Calibration-free

Orifice Plate Flowmeter
