About the measuring accuracy of metal tube float meter scale

Abstract: the scale of metal tube float flowmeter measurement accuracy of the information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. With the development of instrument and meter industry now, because the characteristics of metal tube float flowmeter advantages ( And small pressure loss, wide detection range, easy to use) Has become a commonly used in industrial automation process control flow of a measuring instrument, it can be used to measure liquid, gas. More flow meter manufacturers choose model price quote you are welcome to inquire, here is about the measuring accuracy of metal tube float meter scale details. With the development of instrument and meter industry now, because the characteristics of metal tube float flowmeter advantages ( And small pressure loss, wide detection range, easy to use) Has become a commonly used in industrial automation process control flow of a measuring instrument, it can be used to measure liquid, gas and steam flow, especially suitable for low velocity of small flow of medium flow measurement. So we must pay attention to when installation, ensure the normal use of metal tube float flowmeter and ensure its accuracy. Try to avoid direct sunlight and high temperature environment ( ≥ 65℃) So as not to reduce the capacity and life of lithium-ion batteries. In order to guarantee the normal work of the metal rotameter and meet the requirements of measurement accuracy, the general should pay attention to the following: 1. Must be vertical metal rotameter installed on no vibration of the pipeline, the fluid flows through the flowmeter from bottom to top, and vertical degree is better than 2 & deg; When mounted horizontally horizontal Angle is better than that of 2, & deg; , for the convenience of maintenance and replacement meter, measuring pipeline cleaning, piped in process of metal tube float flowmeter should add bypass and bypass valve. 2. Metal tube flow meter at the entrance of straight pipe length should be more than 5 times the pipe diameter. Export straight pipe should be 250 mm. 3. If the medium containing ferromagnetic material, magnetic filters should be installed; If the medium containing solid impurities, consideration should be given to the valve and adding filter between straight pipe. 4. When used for gas measurement, should guarantee the pipeline pressure is not less than five times the flow pressure loss, to float a stable job. 5. Heat insulation protection measures should be taken to, if the medium to be measured temperature higher than 220 ℃ or fluid temperature is too low crystallization occurs easily. Should choose clip model for cooling or heat preservation. 6. Pipe flanges, fastener, flange gasket and flowmeter standard to make the same 7 meters installed and run. Metal pipe flow meter failure usually occur in the device has just started, because the pipeline blow wash not clean, and float by solid particles sticking phenomenon, the indicator pointer is parked in a fixed position. First of all should be closed the valve on both sides of the flowmeter at this moment, and then remove the flange, remove float washed, packed again. Note on the fastening flange nut to balance tight, and take good washer. 8. Process pipeline flange must be flange with meter coaxial and parallel to each other, in order to avoid deformation caused by pipe flowmeter. Pipe supports properly to avoid the pipeline vibration and reduce the axial load meter, measuring control valve should be installed downstream of the flow meter in the system. 9. Install around at least 10 cm, because the instrument is through the magnetic coupling signal so in order to guarantee the performance of the instrument, ferromagnetic materials are not allowed to exist. If specific pressure calibration gas in the export direct emissions into the atmosphere, measuring gas meter. Will have an air pressure drop in the float, and cause data distortion. If this is the working condition, a valve should be installed at the export of instrument. 10. Be especially careful. Due to the uneven pressure, under the action of the installation of PTFE lining instrument. PTFE will deformation, so the flange nut evenly tighten symmetry. 11. Try to avoid direct sunlight when installation display, instrument with liquid crystal display (LCD). So as not to reduce the service life of the LCD. Metal tube flow meter as a important one in the flow meter now, now the development of high speed, zui new developed the third generation of metal tube float flowmeter, it further improved the availability and advantage of metal tube float flowmeter, it has the following characteristics: a forming inner and outer taper pipe one-piece, solid concise measurement tube no dead Angle, float rotating not easy blockage, magnetic element is not affected by the magnetic field. Low pressure loss design, modular, intelligent, card type indicator. New ESK transmitter sync with the international market! The introduction of foreign advanced computing software to guarantee accurate calculation. Medium, the viscosity, density, temperature, pressure multistage correction. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
