3.4.12 Zero calibration
The procedure for zero calibration is contained in the converter handbook. However, the
following information should be considered when installing the meter.
CAUTION!
The fitted burst disc will be suitable for the flow rates and process conditions specified on the
original order. If the process conditions alter in any way, it is recommended that you contact the
manufacturer for advice regarding suitability.
If the process product is hazardous (in any way) it is recommended that an exhaust tube is
connected to the NPT male thread of the burst disc and the pipe routed so that the process
product can be discharged to a safe area. Use a tube with a diameter large enough AND routed in
such a way, so that pressure cannot build up in the meter case.
Zero calibration
1
Where the meter has been installed vertically, install shut-off valves either side of the meter to assist with zero cali-
bration.
2
If the process flow cannot be stopped, install a bypass section for zero calibration.
