是我公司根据市场和用户的要求新开发研制的一种高科技产品,也是玻璃转子流量计的一次革新和突破。 LYC type glass tube rotor flowmeter is a high-tech product newly developed by our company according to the requirements of the market and users. It is also an innovation and breakthrough of glass rotor flowmeter. In addition to the original glass rotor flowmeter's intuitive reading, good anti-corrosion performance and simple structure, this product can also output a standard electric signal of 4-20mA. It can be used together with the secondary meter to achieve remote transmission display, recording, accumulation, alarm and other functions, and the meter signal can be input into the computer for networking and use, to achieve a variety of functional applications and options. The flow meter is installed on the site to display the flow rate directly, which is very convenient for users to use, so it is a variety of industrial departments and scientific research units for chemical, chemical fiber, pharmaceutical, environmental protection, petroleum and other scientific departments to measure, control, adjust, and measure the flow of various liquids and gases The ideal instrument for accumulation.
的安装及使用 Installation and use of glass rotor flowmeter
The glass tube rotor flowmeter is an indicator instrument that directly observes the fluid flow in the pipeline through the conical glass tube engraved with a flow scale and the position and height of the float in the tube. It is used to measure the flow of one-way media such as non-turbid liquids or gases. It is more convenient and intuitive than other instruments. Therefore, it is widely used in various industrial departments and scientific research units.
在使用安装前,应先检查其技术参数如:测量范围,精确度等级,额定工作压力,温度等参数是否符合使用要求。 Before using the glass rotor flowmeter , check its technical parameters such as: measurement range, accuracy level, rated working pressure, temperature and other parameters that meet the requirements for use. Before installation, the top lining for transportation protection should be removed. And check the cone tube for damage, whether the float can move up and down freely, and it can be installed only after it is normal. The newly installed pipeline should be flushed before the glass rotor flowmeter is installed. The minimum graduation value of the rotor flow meter should be below and installed vertically on the pipeline without vibration. The angle between the center line of the rotor flow meter and the plumb line should not exceed 5 degrees. Large-caliber flowmeters are heavy. To avoid pipe bending, measures such as reinforcement and support can be taken if necessary. It is also necessary to prevent the rotor flowmeter from being subjected to excessive tension, pressure, and torque during installation. So as not to generate excessive external force and damage the tapered tube. According to different working conditions in use, if necessary, a filter should be installed upstream of the rotor flowmeter to prevent contamination by impurities and block the rotor flowmeter. If the fluid is unstable and has a pulsating flow, a buffer can be installed to ensure the good measurement of the rotor flow meter to eliminate the pulsating flow. When the rotor flowmeter is in use, first slowly open the control valve on the upstream pipe of the flowmeter, and then use the regulating valve to adjust the flow rate, so as to avoid the sudden rise of the float to cause damage to the cone tube. In order to ensure the measurement accuracy of the rotor flow meter in use, it is recommended that the common flow rate of the measured fluid be selected to be more than 60% of the upper limit value of the flow rate of the rotor flow meter.
