Before using and installing the metal tube float flowmeter, it is necessary to check its technical parameters, such as: measuring range, accuracy class, rated working pressure, temperature and other parameters, whether they meet the requirements of use.Before installation, the top liner that plays the role of transportation protection in the V-cone flowmeter should be removed.And check whether the cone tube is damaged, whether the float can move up and down freely, confirm the normal before installation.The newly installed piping shall be flushed clean before installation of the metal tube float flowmeter.The minimum indexing value of the metal tube float flowmeter should be below and installed vertically on the non-vibrating pipe. The Angle between the center line of the metal tube float flowmeter and the plumb line should not exceed 5 degrees.Large-caliber V-cone flowmeter is heavy, in order to avoid the bending of the pipeline, necessary measures can be taken to reinforce the bearing and so on.It is also necessary to avoid large pull, pressure, torsion and other forces of the metal tube float flowmeter during installation.In order not to produce excessive external force and damage the cone tube.According to different working conditions in use, if necessary, a filter should be installed in the upstream of the metal tube float flowmeter to prevent contamination of impurities and plug the metal tube float flowmeter.If the fluid is unstable and there is pulsating flow, a buffer can be installed to eliminate the pulsating flow in order to ensure the good measurement of the metal tube float flowmeter.When the metal tube float flowmeter is in use, the control valve on the upstream pipeline of the V-cone flowmeter should be slowly opened first, and then the regulating valve is used to adjust the flow, so as to avoid the sudden opening of the float rapidly rising hit the cone tube.In order to ensure the measurement accuracy of the metal tube float flowmeter in use, it is recommended that the common flow of the measured flow body should be more than 60% of the upper limit of the flow of the metal tube float flowmeter.

Electromagnetic flowmeter according to the relationship between the use of medium there are two categories: liquid and gas, which is the most important attention when ordering;2, electromagnetic flowmeter diameter size, (generally is conventional, such as non-target, do is can do, the cost will be relatively large);3, the selection of flow range, generally choose rated flow is greater than the flow condition.
