Steam and energy outputs
Add synchronized pressure and temperature inputs when compensated mass flow, standard volume or energy is required. Dryness, condensate and wet-steam risk remain separate application checks.

VORTEX MEASUREMENT WITH A DEFINED APPLICATION BOUNDARY
Reliable when the fluid, piping and operating range are selected together
A vortex meter converts shedding frequency behind a bluff body into flow. The principle offers no moving parts and a direct frequency output, but dependable performance still depends on single-phase flow, adequate Reynolds number, stable velocity, controlled piping disturbance and a vibration-aware installation.
Usable low-flow limit
The lower cut-off is set by Reynolds number, density, sensor signal and vibration—not by transmitter rangeability alone. Shizhong sizes the meter against minimum, normal and maximum conditions.
Installation integrity
Elbows, valves, reducers, pulsation, pipe stress and mechanical vibration are reviewed before the straight-run and support arrangement are approved.
Applicable full-bore standards
ISO 12764 · GB/T 25922 · ASME MFC-6
These documents address vortex measurement in a full circular conduit for steady or slowly varying, single-phase liquid, gas or steam service. Their installation and influence-quantity guidance is applied together with the selected meter's approved datasheet and calibration basis.
Important boundary
Insertion vortex meters are separate project designs
ISO 12764 and ASME MFC-6 exclude insertion-type vortex meters. Any larger insertion design therefore needs its own geometry, coefficient, installation, structural and acceptance basis. ISO 5167 is a differential-pressure constriction standard and is not used as a vortex-product conformity claim.
Vortex measurement engineered around the fluid and operating range
A bluff body creates alternating Kármán vortices whose shedding frequency is proportional to mean velocity over the validated operating range. Shizhong pairs the primary sensor, electronics, process connection and optional pressure/temperature compensation with the actual medium and duty. Public performance is stated by model, size, fluid, Reynolds number and installation basis; the selection does not transfer one universal accuracy, turndown or straight-run claim across every application.
