MT100 Multipoint Flow Meter

Specifications

Instrument
■ Measuring Capability
Multi-point, averaging flow rate system for air and gases in large
diameter pipes and rectangular ducts; provides flow rate, totalized
flow, temperature.
■ Basic Style
MT100M: Insertion with two or more sense points on one or more
mast-type flow element probes; minimum of two (2)
points per mast; maximum of eight (8) points on single
mast.
MT100S: Insertion with up to 8 single-point flow elements.
■ Flow Measurement Range
MT100M: 0.25 SFPS to 150 SFPS [0,07 NMPS to 46 NMPS]
MT100S: 0.25 SFPS to 1000 SFPS [0,07 NMPS to 305 NMPS]
Air @ standard conditions, 70 °F and 14.7 psia [21,1 °C and 1,01325 bar(a)]
■ Temperature Measurement Range
-50 °F to 500 °F [-45 °C to 260 °C] or
-50 °F to 850 °F [-45 °C to 454 °C]
■ Media/Fluid
All air, gas and gas combinations that are compatible with the flow
element's wetted materials.
■ Accuracy

±2% of reading, ±0.5% of full scale
Flow (MT100S)
±0.75% of reading, ±0.5% of full scale
Temperature
±2 °F [±1 °C]
■ Repeatability
Flow

■ Temperature Coefficient (Flow)
With optional temperature compensation, valid from 10% to 100%
of full scale calibration
Maximum ± 0.015% of reading/°F up to 850 °C [± 0.03% of
reading/°C up to 454 °C]
■ Turndown Ratio
Normally factory set and field adjustable from 2:1 to 100:1 within
calibrated range; higher ratios possible with factory evaluation of
application.
■ Temperature Compensation
Standard: ±30 °F [± 16 °C]
Extended (optional): ±100 °F [± 55 °C]
■ Calibration
Performed using equipment traceable to NIST (US National
Institute of Standards and Technology) and ISO/IEC 17025
international standards for test lab quality systems.
