Balanced Flow MetersPRODUCT PORTFOLIO
Primary elements for real process conditions
Standard Orifice PlatesStandard Orifice Plates
Corner / flange / D-D/2 taps
A proven differential-pressure primary element for liquids, gases and steam, manufactured for traceable dimensions and repeatable installation.
Technical detailsDual-Beta Orifice Plates
Two independent beta sections
Two independent ฮฒ sections in one assembly, each designed to ISO 5167-2:2022 โ enabling wide-range measurement with standardized orifice elements.
Technical details
Venturi TubesVenturi Tubes
Convergent throat and diffuser
A classical convergent-throat-diffuser primary element for stable measurement where energy recovery matters.
Technical detailsBore-Venturi Balanced Flow Meters
Eight bore-venturi flow paths
Eight bore-venturi holes with an integrated central cone โ combining balanced flow conditioning with venturi pressure recovery for high accuracy and low pressure loss.
Technical detailsBalanced Flow MetersBalanced Flow Meters
Multi-hole balanced element
A multi-hole differential-pressure primary element designed to distribute the flow field and reduce permanent pressure loss compared to single-hole orifice plates.
