dicator is installed between nozzle and measurement transducer, by which customer observes whether foam in delivering oil. Accuracy will be affected because of much foam or bubble. Diagram 2-33 is shown a common oil indicator in domestic market. Since this kind of oil indicator has big pass section than that of fuel dispenser two ends of pipe, velocity of flow of passing oil is reduced so as to facilitate observation. If oil transparent, that is, no foam in it, fuel dispenser is in normal state. If opaque with visible foam, it is shown that there is gas in oil. Don’t refuel until foam disappears in oil indicator. If passed long time, foam in oil indicator still exists so that the accuracy of fuel dispenser is affected, some troubleshooting measures on vapor separator should be considered. Disassemble low cover and examine gasket and joint face if found leakage. Oil in pipe should be discharged completely in maintenance, keeping appropriate tightness to bolts as reassembly in case of crunching glass. 1-Frame 2-Sink-screw 3-Seal gasket 4-Glass 5-Seal 6-Cover Diagram 2-33: Ball-shaped oil indicator structure Columnar oil indicator, shown in Diagram 2-34, is installed on the top of gantry fuel dispenser, the convex end connected with pipe jointer of fuel dispenser, the concave end of it with hose unit. Foam is observed through the glass pipe of columnar oil indicator. If found leakage, disassemble oil indicator from jointer, clean waste or replace damaged gasket. Replace glass pipe when found crackle on it. Be careful of reassemble hose jointer and oil indicator after maintenance in case of crunch glass pipe. 1-Fra fuel dispenser me 2-Glass pipe 3-Seal ring 4-O-ring Diagram 2-34: Columnar oil indicator Firstly empty oil in fuel dispenser when deal with oil indicator’s trouble, for fear of oil splashing. There is a kind of method to empty here: loose bolt on corrugated pipe after start up fuel dispenser. In this state, no oil in tank is suck into fuel dispenser, but oil in fuel dispenser is discharged out continually. After stop fuel dispenser

not used block number　　 0 = intermediate　　 blocks　　 The maximum number of blocks is defined by the buffer size of the receiving device　　 (around 1 Kbytes in the IFSF Dispenser Application) and the Block Length.　　 Example: If the fuel dispenser Block Length is 32 the maximum number of blocks is 32 (numbered　　 from 0 to 31). If the Block Length is 228 the maximum number of blocks is 4　　 (numbered from 0 to 3).　　 When the message is cut blocks are created by the communication layer according to　　 the maximum possible block length on the network.　　 Blocks may arrive at a recipient node out of sequence. It is up to the recipient node　　 application to ensure that this is taken into consideration when the message is　　 reassembled.　　FP2_1.89 IFSF STANDARD FORECOURT PROTOCOL June 2005　　 COMMUNICATION SPECIFICATION　　Page: 28　　 Byte 6 (BL Byte ) informs the application if a message has been cut up into blocks.
