LR Flanged Thermal Mass Flow Meter for Gas
LR flanged thermal mass flow meter for dry gas, flange DN25 to DN150, direct mass flow without pressure or temperature correction.
Selection guidance
How to specify a thermal mass flow meter
Three inputs decide the LR configuration.
022
Connection and pipe size
The flanged version covers DN25 to DN150. The same family also offers thread (DN25 to DN50) and insertion (DN125 to DN2000) versions.
033
Range and output
Accuracy is ±(1.5 + 0.5 FS)%. Normal medium velocity is 0.56 to 56 Nm/s, extended to 100 Nm/s by arrangement. Outputs include 4-20 mA, pulse, RS485 and HART.
