Installation Requirement for Gas Turbine Flow Meter:
(1)In order to obtain a stable and accurate flow measurement, it is very important that the flow meter is installed correctly in the pipe system;
(2)Flow meter need to be installed on horizontal pipeline.
(3)The inner diameter of the flow meter need to be as same as inner diameter of pipeline, and the axis of the flow meter should be concentric with the axis of the pipeline during installation;
(4)Recommend to install indoors. If need to install outdoors, please make good protection from direct sunlight and rain;
(5)In order to ensure the normal use of the medium is not affected when the flow meter is overhauled, a shut-off valve should be installed on the upstream and downstream of the flow meter. A bypass pipeline should be provided.
(6)The flow control valve must be installed downstream of the flow meter, and the upstream valve must be fully open when the flow meter is used.
Gas Turbine Flow Meter Maintenance:
(1)Gas turbine flow meter need to do oil filling operation regularly to ensure bearings work smoothly.
(2)There’s oil filling operation indication on each Q&T gas turbine flow meter’s body. Follow the indication to do oil filling regularly is fine.
