The installation-specific measured error depends on the installation conditions on site, such
as the nominal diameter, wall thickness, real pipe geometry or medium. The maximum
installation-specific measured error is:
Nominal diameter Installation-specific error limits
[mm] [in]
15 ½ ±16.12 % o.r.
25 1 ±10.50 % o.r.
40 1½ ±7.17 % o.r.
50 2 ±6.22 % o.r.
65 2½ ±6.67 % o.r.
80 3 ±6.08 % o.r.
100 4 ±5.48 % o.r.
150 6 ±4.91 % o.r.
200 8 ±4.69 % o.r.
300 12 ±4.45 % o.r.
400 16 ±4.42 % o.r.
500 20 ±4.37 % o.r.
600 24 ±4.33 % o.r.
1000 40 ±4.05 % o.r.
2000 80 ±3.92 % o.r.
3000 120 ±3.88 % o.r.
4000 160 ±3.86 % o.r.
The determined installation-specific measured error covers the following application
scenarios:
Pipe geometry In accordance with ASME B36.10M-2015
Deviation of the entry for the measuring pipe
outer diameter
Max. ±1 % or min. ±0.5 mm (±0.02 in)
(average tolerance class D2/T3 as per DIN EN ISO 1127)
Deviation of the entry for the measuring pipe
wall thickness
Max. ±10 %
(average tolerance class D2/T3 as per DIN EN ISO 1127)
Deviation of the sensor distance • DN 15 to 65 (½ to 2½"): max. ±1 mm (±0.04 in)
• DN 80 to 200 (3 to 8"): max. ±2 mm (±0.08 in)
• DN 300 to 4000 (12 to 160"): max. ±1 % of outer diameter
Number of traverses • DN 25 to 600 (1 to 24"): 2 traverses
• DN 1000 to 4000 (40 to 160"): 1 traverse
