(1) Accuracy options vary by model. Models CMF010, CMFS010, CMFS015, sensors with Model 2200S transmitter, and all high-

temperature models have fewer accuracy options. See Ordering information on page 54.

Liquid Accuracy

(2)

(2) Stated flow accuracy includes the combined effects of repeatability, linearity, and hysteresis. All specifications for liquids are based on

reference conditions of water at 68 to 77 °F (20 to 25 °C) and 15 to 30 psig (1 to 2 bar), unless otherwise noted.

±0.05% of rate

(3)(4)(5)

(3) When flow rate is less than zero stability / 0.0005, accuracy = ±[(zero stability / flow rate) × 100]% of rate, and

repeatability = ±[½(zero stability / flow rate) × 100]%.

(4) When ordered with the ±0.10% factory calibration option, accuracy on liquid = ±0.10% when flow rate

≥

zero stability / 0.001. When flow

rate < zero stability / 0.001, accuracy = ±[(zero stability / flow rate) × 100]% of rate and repeatability = ±[½(zero stability / flow rate) ×

100]% of rate.

(5) For cryogenic applications (below –100 °C), mass flow accuracy is ±0.35% of rate.

±0.10% of rate

(6) When flow rate is less than zero stability / 0.001, accuracy = ±[(zero stability / flow rate) × 100]% of rate and

repeatability = ±[½(zero stability / flow rate) × 100]% of rate.

(7) When flow rate is less than zero stability / 0.0035, accuracy equals ±[(zero stability / flow rate) × 100]% of rate and repeatability equals

±[½(zero stability / flow rate) × 100]% of rate.
