Signet Model 2552-3 metal magmeter is a rugged insertion flow sensor that permits hot-tap access to the pipe stream. The robust design and durable metal housing provide accurate flow sensing in harsh environments. It fits into pipe sizes from 2 in. to 102 in., and its patented design offers a dynamic flow range of 0.15 ft/s to 33 ft/s (0.05 m/s to 10 m/s) with repeatability of ±0.5% of reading at 25 °C.
