Please open the front cover of the Coriolis mass flow meter, it will be like shown in above picture. Please push the terminal to the left, make it same as others. That\u2019s all.<\/p>\n

3)\u00a0 \u00a0Vibration stops<\/p>\n

If the coriolis mass flow meter has worked normally for some time and appears “Vibration stop” on the screen, then it means there’re some impurities (solid particles) in the measuring tube, then you need to wash the measuring tube.Then re-install the flowmeter and let liquid flow through the measuring tube at a normal flow rate. Please make sure that all the valves at inlet should be open.\u00a0 Please also check if the flange centre distances are aligned.<\/p>\n

4)\u00a0Total flow cleared to zero<\/p>\n

Please follow the following operations to clear the total flow of Coriolis mass flow meter to zero.<\/p>\n

Please\u00a0open\u00a0the\u00a0front\u00a0lid\u00a0of\u00a0the\u00a0transmitter,\u00a0and\u00a0you’ll\u00a0find\u00a0the\u00a0terminal\u00a0at\u00a0the\u00a0right\u00a0side\u00a0of\u00a0the\u00a0displaying\u00a0screen.\u00a0Please\u00a0turn\u00a0the\u00a0K1\u00a0to\u00a0the\u00a0same<\/p>\n
