Asphalt flow meter installation and use instructions

Abstract: Asphalt flow meter installation and use instructions The information is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. The instrument should be installed at room temperature as much as possible. When measuring high-viscosity liquid, the liquid is generally heated to reduce the viscosity, and then circulated in the pipeline. When the instrument is deactivated, the liquid filled in the instrument becomes viscous due to cooling. If it is to be activated again, steam or steam must be used. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the installation and use instructions of asphalt flowmeters. The instrument should be installed at room temperature as much as possible. When measuring high-viscosity liquid, the liquid is generally heated to reduce the viscosity, and then circulated in the pipeline. When the meter is out of use, the liquid filled in the meter becomes viscous due to cooling. If it is to be activated again, it must be heated outside the meter body with steam or other methods to reduce the viscosity of the liquid, and it can be used after the viscosity of the liquid in the meter is reduced. Otherwise, the mucus will bite the transmission parts and cause damage to the instrument. Do not install it in the occasion of harmful gas and strong heat radiation to prevent the damage to the counter part of the instrument. The direction of the instrument installation should make the direction of the arrow shown on the instrument shell consistent with the flow direction of the liquid, and the installation position should be paid attention to to facilitate reading. Before the instrument is installed, the pipeline must be thoroughly cleaned. In the entire pipeline system, if there is no strict filtering device, a filter should be installed in front of the instrument to prevent the flow of impurities entering the pipeline in the meter should not increase or decrease sharply. Avoid the phenomenon of pipeline vibration, hydraulic shock and rapid pressure fluctuation, otherwise it will affect the normal operation of the instrument. The asphalt shaft in the instrument should be installed in a horizontal position as much as possible, that is, the dial should be installed in a vertical position (grading).“0”should be above) to reduce the friction between the asphalt gear and the housing and reduce the wear of the parts. Due to the different installation positions, in order to facilitate reading, the counter (head) can be rotated 90°or 180°, Each instrument is calibrated with No. 7 mechanical oil at room temperature when it leaves the factory. At room temperature, the viscosity of the oil is about 10mpa.s. If the viscosity of the liquid used by the user is quite different from this, the double-layer gear can be replaced, and it is strictly forbidden for steam and water to pass through the instrument. The temperature of the liquid to be measured should not be higher than the specified value, otherwise, the meter will not work normally, or even stuck. Liquid temperature changes can also cause additional errors that are affected by viscosity. In addition, the increase in temperature also causes the volume of the crescent space to increase, which is the instrument“walk slowly”, When the measuring chamber is cast iron and the oval gear is cast aluminum, the additional error is +0.14%/100°C, the meter should be installed at the outlet of the pump, and the flow regulating valve should be installed downstream of the meter. When using, first open the upstream shut-off valve, and then slowly open the downstream flow regulating valve or shut-off valve. It is strictly forbidden to open or close it suddenly. When the meter is in use, the meter should be filled with liquid. There should be no gas mixed in the liquid to be measured, otherwise the mixed volume of gas and liquid will be measured, which will make the measurement inaccurate. When the liquid is mixed with gas, a gas separator must be installed upstream of the instrument. When the flow rate exceeds the specified maximum flow rate, the wear of asphalt increases with the increase of rotation speed, and the pressure loss increases sharply, so it should be avoided. Below the minimum flow rate, although it can still be measured, the error will increase. The starting flow of the flowmeter is about 2% of the maximum flow, and the normal working flow is preferably 70%-80% of the maximum flow. When measuring high-viscosity liquids, the liquid is generally heated to reduce the viscosity, and then circulated in the pipeline. When the meter is out of use, the liquid filled in the meter becomes viscous due to cooling. If it is to be activated again, it must be heated outside the meter body with steam or other methods to reduce the viscosity of the liquid, and it can be used after the viscosity of the liquid in the meter is reduced. Otherwise, the mucus will bite the transmission parts and cause damage to the instrument. The above is the whole content of this article.
