Definition of pressure levels:
No. 0: injection pressure up to 16 bars
No. 1: injection pressure >16 to 25 bars
No. 2: injection pressure >25 to 40 bars
No. 3: injection pressure >40 to 60 bars
No. 4: injection pressure >60 to 100 bars
No. 5: injection pressure >100 to 160 bars
No. 6: injection pressure >160 to 250 bars
No. 7: injection pressure >250 to 430 bars
No. 8: injection pressure >430 to 700 bars
No. 9: injection pressure >700 bars
Pressure/volume recorder directly attached to each pump where injection point, date and time are noted by hand. More recent devices record date and time and print a report after the injection process (point, no., total volume, highest pressure). Computer-aided measuring instruments record the injection sequence, print a report and acquire data for further processing by PC. In addition, the devices can send control signals to the pumps, in order to perform pre-programmed injections or for influencing the injection sequence by means of external signals.
