Hi, I urgently need some advice on an installation where a Coriolis sensor is used for flow and density measurement.
When flow is routed through the sensor an drive is reported to 100%. Severe two phase alarm and drive overrange is reported. There is no reliable measurement of flow.
I have done several smart meter verifications and they always pass.
When I do a verify zero, it fails. Then I calibrate new zero and the meter reports zero flow. If left alone for some time, it starts showing flow when there is no flow in the line. A new verify zero fails and a new calibrate zero is needed.
The system is designed for a maximum flow of 7500 L/min, so this might be to big for the task at hand.
I tried to contact support, but in my region only a sales representative was available and he could not help. Any help regarding this installation is appreciated.
