Standards
 
The level gauge satisfies the protection requirements of : 
Electromagnetic compatibility 
Electromagnetic compatibility 
directives followed for EU 
countries 
Directive 89/336/EEC in conjunction with EN 61326-1(A1&A2) 
and EN 61000-6-2 standards. It also respects the NAMUR NE 
21/98 standard. Protection against EMC emissions is only 
guaranteed when the device is used in metal tanks (except when 
the device is equipped with coaxial probes). 
Low voltage electrical equipment 
Other EU directives
Directive 73/23/EEC modified by Directive 93/68/EEC (art.13) in 
conjunction with the EN 61010-1 standard. 
ATEX* 
Directive 94/9/EC in conjunction with EN 50014, EN 50020 and 
EN 50284 standards. 
Refer to the BM 102 MICROFLEX KEMA 00 ATEX 1101X 
Supplementary Installation and Operating Instructions for further 
information. 
 
5.1.1 Accuracy 
Due to the method of measurement, which primarily determines distance, the measuring accuracy 
is specified only as a factor of distance. For that reason, all data in this section refers to the 
measured distance. 
 
Standard calibration 
 
Error of measurement (mm) 
Distance from flange (m)
