1. The rotameter must be installed vertically on a pipeline without vibration. The fluid flows through the flow meter from bottom to top, and the verticality is better than 2°.2. In order to facilitate the maintenance and replacement of the flowmeter and cleaning the measuring pipeline, the metal tube float flowmeter installed on the process pipeline should be equipped with a bypass pipeline and a bypass valve;3. There should be a straight pipe section with a length of more than 5 times the pipe diameter at the inlet of the rotameter, and a 250mm straight pipe section at the outlet;4. If the medium contains ferromagnetic substances, a magnetic filter should be installed; if the medium contains solid impurities, a filter should be installed between the valve and the straight pipe section;5. When used for gas measurement, ensure that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to make the float work stably;6. When measuring gas, if the gas is directly discharged to the atmosphere at the outlet of the flow meter, a valve should be installed at the outlet of the meter, otherwise it will produce a pressure drop at the float and cause data distortion.7. In order to avoid deformation of the flowmeter caused by the pipeline, the flange of the process pipeline must be coaxial and parallel to the flange of the flowmeter, and the pipeline must be supported to avoid pipeline vibration and reduce the axial load of the flowmeter. Control in the measurement system The valve should be installed downstream of the flow meter:8. When installing the instrument with PTFE lining, do not overtighten the flange nut randomly asymmetrically, so as not to cause deformation of the PTFE lining;9. For meters with LCD display, avoid direct sunlight on the display to avoid reducing the service life of the LCD; for meters with lithium battery power, avoid direct sunlight and high temperature environments (≥65°C) to avoid reducing the capacity and capacity of the lithium battery. Life span.
