Design fundamentals
Dependent on the flow:
• Flow
Zero point stability ÷ (Base accuracy ÷ 100)
– Max. measured error: ±Base accuracy in % o.r.
– Repeatability: ± ½ · Base accuracy in % o.r.
• Flow < Zero point stability ÷ (Base accuracy ÷ 100)
– Max. measured error: ± (Zero point stability ÷ measured value) · 100% o.r.
– Repeatability: ± ½ · (Zero point stability ÷ measured value) · 100% o.r.
o.r. = of reading
