Pneumatic averaging
A common positive- and negative-pressure circuit feeds one DP transmitter. The complete supplied array uses an approved system coefficient.
Patented multi-point velocity-array measurement
Full-Section Matrix Flowmeters — Multi-Point DP Velocity-Array System
A patented multi-point differential-pressure array engineered for large circular pipes, rectangular ducts and gas-flow profiles that a single-point or single-bar probe may not represent.

ONE ARRAY · THREE SIGNAL ARCHITECTURES
Choose the measurement architecture before finalizing the grid
A matrix array samples more of the section than a single probe, but pressure averaging is not automatically the same as arithmetic velocity averaging. Shizhong selects the signal architecture, grid, coefficient and acceptance method together so that the delivered calculation matches the actual duct and measurement objective.
Zoned averaging
Separate duct zones provide diagnostic visibility when the profile is asymmetric or the operating load changes substantially.
Multi-channel integration
Local velocities are calculated from individual DP channels and integrated with defined area weights for the strongest traceability.
Patented Shizhong architecture
Full-section sensing with integrated flow conditioning
CN212082473U covers the combination of an upstream flow conditioner, symmetric multi-branch positive-pressure array, downstream negative-pressure structure and centralized pressure connections. The patent establishes the structure; project performance remains tied to the supplied geometry and approved verification basis.
Standards boundary
Velocity-area principles—not a transferred ISO coefficient
ISO 3966:2025 informs Pitot-static velocity-area practice. ISO 16911-1/-2 supports stationary-source reference and automated measurement. Neither standard assigns a universal coefficient, accuracy or straight run to a proprietary matrix array, and ISO 5167 does not cover this product class.
Full-section gas-flow measurement engineered around the actual duct
The Shizhong Full-Section Matrix Flowmeter combines a multi-point sensing array with an integrated flow-conditioning structure to sample a broader area of the measuring section. Each system is designed around the actual duct geometry, upstream disturbance, gas properties, maintenance conditions and acceptance method. Project performance is established through an approved system coefficient, representative calibration or site correlation—not a universal coefficient transferred between installations.
