ST51 flowmeter is ideal for the monitoring industrial plant greenhouse gases. It features a no-moving parts design that’s non-clogging and operates over a wide flow range with low-flow sensitivity. It comes in an explosion-proof transmitter, and it features a thermal mass, insertion-style flow element with flow accuracy to ±1% of reading over a broad flow range from 0.3 to 400 SFPS (0.08 to 122 MPS).
