1. Accuracy of Metal Tube Float Flow Meter TLLZ and AFLZ series metal tube float flow meters adopt the principle of variable area measurement and are suitable for measuring the volumetric flow rate of liquids and gases. Widely used in flow measurement processes under complex and harsh environmental conditions, as well as various medium conditions, such as petroleum, chemical, power generation, pharmaceutical, food, water treatment, etc. How to achieve accurate measurement with a flow meter? How to make a metal tube float flow meter work normally and achieve the required measurement accuracy? The following points should be noted: The inlet of the flow meter should have a straight pipe section of at least 5 times the diameter of the pipe, and the outlet should have a straight pipe section of 250mm. A bypass should be added to the metal tube float flow meter to facilitate troubleshooting and ensure that it does not affect production during blowdown; ·If the medium contains solid impurities, it should be considered to install a filter between the valve and the straight pipe section; ·If the medium contains ferromagnetic substances, a magnetic filter should be installed; When the temperature of the tested medium is higher than 220 ℃ or the fluid temperature is too low to cause crystallization, insulation protection measures should be taken, and a jacket type should be selected for cooling or insulation; ·When used for gas measurement, it should be ensured that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to ensure the stable operation of the float; ·The pipeline flange, fasteners, gaskets, and flowmeter flange must meet the same standards to ensure the normal installation and operation of the instrument; ·Flowmeters generally do not require maintenance after the device is running normally. Malfunctions often occur when the device is just started, and due to poor cleaning and tidiness of the pipeline, the float is stuck by solid particles. At this time, the pointer of the indicator stops at one position and does not move. At this point, first close the valves on both sides of the flowmeter, then remove the upper flange, take out the float for cleaning, and reinstall it. Pay attention to tightening the flange nuts evenly and place washers on them; ·In order to avoid deformation of the flow meter caused by the pipeline, the flange of the process pipeline must be coaxial and parallel to the flange of the flow meter, and the pipeline support should be appropriate to avoid pipeline vibration and reduce the axial load of the flow meter. The control valve in the measurement system should be installed downstream of the flow meter. The instrument for measuring gas is calibrated at a specific pressure. If the gas is directly discharged into the atmosphere at the outlet of the instrument, it will cause a pressure drop at the float and cause data distortion. If such working conditions are met, a valve should be installed at the outlet of the instrument; ·Due to the fact that the instrument transmits signals through magnetic coupling, in order to ensure its performance, ferromagnetic materials are allowed to be present at least 10cm around the installation site without interference; ·When installing instruments with LCD displays, try to avoid direct sunlight on the display to avoid reducing the lifespan of the LCD. ·Instruments powered by lithium batteries should be installed in environments with direct sunlight an
