It can happen. RV series flow dividers have their own accuracy. The physiological error in standard flow dividers is 3% for a load difference of up to 30 bar. Therefore, if the cylinders rise simultaneously within the 3% value, the product is compliant. The MIA-FD series, on the other hand, is designed for large load differences and has an error of up to 2% with differences of up to 170 bar.  If the error is greater than indicated, there are several possible reasons often related to the system or operating conditions.
