MT Series Multi-Point Mass Flow Meter
Brand: Fluid Components International LLC (FCI)/MT-Series-Multi-Point-Mass-Flow-Meter/002_FCI_MT_Series_Multi-Point_Flow_Meter.png)
FCI’s MT Series Multi-Point Mass Flow Meters are ideal for today’s most challenging industrial air or gas handling applications and continuous emissions monitoring systems (CEMS).
Inside large combustion or preheater systems, HVac units, ducts or flue stacks, MT Series multi-point flow meters measure flow with exceptional precision under variable thermodynamic conditions.
They are an excellent choice for measuring mass flow almost anywhere variable conditions limit single-point flow meter effectiveness.
Harsh environments, in which temperature, vibration, abrasion and corrosion pose difficulties for other meters, are no problem for the rugged MT Series multi-point flow meters. Instrument accuracy is available to ±2% of reading, with repeatability of ±0.5%.
