5-6-2 :Cautions Related to Flow Rate Measurement
Refer to the instructions on flange mounting for flow-rate measurement, to operate the
transmitter for flow rate measurement.
Always complete zero-point checking before introducing fluid to the pipe. This pre-
caution is warranted since the STR/STE has a structural characteristic that prevents
mounting of an equalizing valve or stop valve.
For vertical pipes with differential-pressure take-out flange port, the high-pressure
side flange and the low-pressure side flange exhibit a level difference. In this case,
determine the zero point by setting LRV.
