GA24: Built with a rugged housing for added process safety, the GA24 offered low flow glass tube measurement with integrated switching. It has since been replaced by newer variants in the VA and DK series. 

Differential Pressure Flowmeters

For proven, flexible flow measurement in a wide range of process conditions.

Using primary elements like orifice plates and averaging pitot tubes, differential pressure meters are suited to high-temperature, high-pressure applications with customizable configurations.
Compact Assemblies

Compact Orifice Plate: A streamlined DP solution that integrates an orifice plate and transmitter into one compact unit. Designed for quick installation and reliable flow measurement in medium to large lines, no impulse lines or extra supports needed. 

Orifice Meter Run Assembly: Pre-calibrated and standardized for smaller line sizes, this ready-to-install assembly ensures stable, accurate measurements in liquid, gas, or steam systems. Ideal for space-constrained setups and repeatable process conditions. 

Specialized Flow Elements

Averaging Pitot Tube: Handles high temperatures and large diameters with ease. This versatile solution is suited for everything from process gases to steam and excels in retrofit installations thanks to its simplified mounting and minimal piping disruption. 

Wedge Flowmeter: Engineered for abrasive and viscous fluids like slurries, coker feeds, or heavy residues. The wedge element resists wear and buildup, providing consistent flow readings in harsh and high-pressure environments. 

Cone Flowmeter: Designed for applications with limited straight run, the cone element delivers stable readings with minimal installation space. Built from stainless steel or specialty alloys to meet demanding chemical or process conditions. 

High Accuracy & High Flow

Flow Nozzle Meter: An ideal fit for high-velocity flows such as steam or feedwater. The nozzle design minimizes pressure loss while delivering reliable, repeatable results for demanding industrial processes. 

Venturi Flowmeter: Engineered for accuracy in large-scale flow systems. Commonly used in energy billing and acceptance testing, it offers low permanent pressure loss and long-term measurement stability even at high Reynolds numbers. 

Vortex Flowmeters

For utility flows, steam measurement, and SIS-compliant energy systems.

Vortex flowmeters detect frequency shifts caused by flow-induced vortices, offering reliable volumetric measurement for steam, gases, and liquids. Ideal for HVAC, district heating, and energy management.
