Resetting Siemens Pressure Transmitters
for fuel tanks up to 35,000 gallons
NOTICE: This Tec-Note applies to transmitters installed August 21, 2006 and thereafter. Heatec Tec-Note 5-04-115 applies to transmitters installed prior to that date.
This document provides information on resetting Siemens pressure transmitters used on all Heatec fuel tanks with capacities up to 35,000 gallons (Figure 1). It applies to Siemens Sitrans P, Series DSIII transmitters 7MF4033-1CA10-1NC7-Z A01+B21+Y01+Y22 (Figure 2).

This document is furnished with all Heatec fuel tanks equipped with the Siemens transmitters. Applicable Siemens user’s manuals are also furnished. The information in these documents should enable users of Heatec tanks to reset the transmitters in the field.
The transmitters are preset at the Heatec factory before the tanks are shipped, but users may need to change these settings for different fuels.
The transmitters are now set to display levels in inches instead of feet as on earlier tanks. A table for converting inch-levels to gallons is included in this document.
