MT86 Multipoint Air and Gas Mass Flow Meter
for Large Line Sizes and Stacks
Mass Flow Meter SummaryThe MT86 insertion type multipoint mass
flow meter combines FCI's highly reliable thermal dispersion,
no-moving parts flow element design with up to 16 flow sensing
points while operating over a wide temperature range up to 850° F
[454° C]. The electronics features continuous built-in testing and
calibration adjustment to prevent signal drift.
The MT86 multipoint mass flow meter is ideal for installation in air
ducts, stacks, or wherever irregular flow profiles reduce the
effectiveness of single-point metering.
