Q & A

Q&A Section with Expand/Collapse Icons

M-2300 Series High-Purity Inline Ultrasonic Flow Meter Q & A

+ What does the M-2300 Series measure, and what makes it unique?
The M-2300 Series uses transit-time ultrasonic technology, where two piezoelectric transducers transmit and receive ultrasound signals. The difference in transit times upstream vs. downstream determines fluid velocity—and thus flow rate. It delivers this in a compact, integrated sensor-plus-electronics unit, simplifying installation.
+ What level of accuracy and repeatability does it offer?
It achieves ±1% full-scale accuracy and ±0.5% repeatability, providing precise and consistent performance.
+ What are the construction and wetted materials?
The wetted components use high-purity PFA (Perfluoroalkoxy alkane), ensuring exceptional corrosion resistance and preventing contamination. The straight flow path eliminates dead legs and obstructions.
+ What sizes and connection types are available?
Available in ¼″, ⅜″, and ½″ tube or fitting connections. Custom sizes may be available—consult the factory for details.
+ Which applications are best suited for the M-2300 Series?

Ideal for high-purity semiconductor applications, including CMP, cooling systems, ECD, electroless deposition, laser equipment, solar PV equipment, track tools, wet clean, wet processing, and chemical distribution systems.
