Your benefits<br />
• Choice of three level operating modes.<br />
• Volume and mass measurements in any tank shapes by means of a freely programmable characteristic curve.<br />
• Choice of diverse level units with automatic unit conversion.<br />
• A customized unit can be specified.<br />
• Has a wide range of uses, e.g.<br />
– for level measurement in tanks with pressure overlay<br />
– in the event of foam formation<br />
– in tanks with agitators of screen fittings<br />
– in the event of liquid gases<br />
– for standard level measurement<br />
Communication protocol<br />
• 4 to 20 mA with HART communication protocol<br />
• PROFIBUS PA<br />
– The Endress+Hauser devices meet the requirements of the FISCO model.<br />
– Due to the low current consumption of 13 mA ± 1 mA, the following number of devices can be operated<br />
on one bus segment if installing as per FISCO:<br />
– up to 7 <strong>Deltabar</strong> S for Ex ia, CSA IS and FM IS applications<br />
– up to 27 <strong>Deltabar</strong> S for all other applications, e.g. in non-hazardous areas, Ex nA, etc.<br />
Further information on PROFIBUS PA can be found in Operating Instructions BA034S "PROFIBUS DP/PA:<br />
Guidelines for planning and commissioning" and in the PNO Guideline.<br />
• FOUNDATION Fieldbus<br />
– The Endress+Hauser devices meet the requirements of the FISCO model.<br />
– Due to the low current consumption of 15 mA ± 1 mA, the following number of devices can be operated<br />
on one bus segment if installing as per FISCO:<br />
– up to 6 <strong>Deltabar</strong> S for Ex ia, CSA IS and FM IS applications<br />
– up to 24 <strong>Deltabar</strong> S for all other applications, e.g. in non-hazardous areas, Ex nA, etc.<br />
Further information on FOUNDATION Fieldbus, such as requirements for bus system components can be<br />
found in Operating Instructions BA013S "FOUNDATION Fieldbus Overview".<br />
