Performance characteristics – metal process isolating<br />

Reference accuracy –<br />
PMD<strong>75</strong>, FMD<strong>77</strong>, FMD<strong>78</strong><br />
The reference accuracy comprises the non-linearity (terminal based), hysteresis and non-reproducibility as per<br />
IEC 60<strong>77</strong>0. The data refer to the calibrated span.<br />
The following applies for the root-extracting characteristic curve:<br />
The accuracy data of the <strong>Deltabar</strong> S are taken into the accuracy calculation of the flow rate with a factor of 0.5.<br />

Total performance – PMD<strong>75</strong><br />
The "Total performance" specification comprises the non-linearity including hysteresis, non-reproducibility, the<br />
thermal change of the zero point as well as the influence of the static pressure (p st = 70 bar (1050 psi)).<br />
All specifications apply to the temperature range –10 to +60 °C (+14 to +140 °F).<br />
