Installation requirements:
1.Before installation flowmeter should be transport protection with the plunger, fillers, etc.
2. Meter should be installed vertically on the no vibration of the pipeline, there is no obvious tilt.
3. Meter inlet joint should be connected with its cone piont.
4. Install the flow time, 4 to fixed connection pipe flowmeter, really should not make the glass tube produces stress.
5. Test medium to clean, if necessary, in the upstream flow meters installed filters.
