ST75V/ST75AV Mass Flow Meter
Brand: Fluid Components International LLC (FCI)/ST75V-ST75AV-Mass-Flow-Meter/002_FCI_ST75V-ST75AV_Mass_Flow_Meter.png)
The ST75 is an accurate, no moving parts, direct mass flow measurement and monitoring solution for fuel gases, air, compressed air, inert and other gas flows within industrial processes.
There are four base models in the series: ST75, ST75A, ST75V, and ST75AV. The "A" suffix models provide enhanced features and HART I/O, the "V" suffix models include built-in Vortab flow conditioners. They are available in six different sizes for direct, in-line installation in line sizes from 1/4" to 2" (6 to 51 mm).
Features- Direct mass, standard volumetric or standard velocity flow measurement
- Triple outputs; flow rate, temperature and total flow
- HART I/O (ST75A, ST75 AV)
- Non-clogging, no moving parts
- 2 line digital display option
- Small, compact design
- Easy installation
