A commercial liquid‑rocket test carried Zhongke Xingtu Tianchen Technology
(Xiamen) Co.'s in‑house ring‑network rocketborne data acquisition system and two
onboard liquid‑level sensors (continuous and point). The ring‑network system
achieved the first domestic full‑vehicle application for this rocket model and
handled all measurement tasks. Both devices operated stably with zero failures
and captured complete flight data.
