Performance specifications
A.1.1
General
Reference conditions
Single Standard probe, 77 °F (25 °C) in water (DC=80) and ambient pressure in a 4-in. pipe
using Trim Near Zone function.
Reference accuracy
± 0.12 in. (3 mm) or 0.03% of measured distance, whichever is greatest
For probes with spacers, the accuracy may deviate close to the spacers. Accuracy may be
affected by remote housing.
