Precautions for installation of small diameter metal rotor flow meter

Abstract: Information on installation precautions for small-diameter metal rotor flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The small-diameter metal rotor flowmeter adopts the variable area measurement principle. The flowmeter has an all-metal structure and is lined with PTFE material. It is suitable for corrosive gases. There are indication type, electric remote transmission type, corrosion resistance type, high pressure type, jacket type, explosion-proof type. With 0-10mA, 4-20. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the installation precautions for small-diameter metal rotor flowmeters. The small-diameter metal rotor flowmeter adopts the variable area measurement principle. The flowmeter has an all-metal structure and is lined with PTFE material. It is suitable for corrosive gases. There are indication type, electric remote transmission type, corrosion resistance type, high pressure type, jacket type, explosion-proof type. With 0-10mA, 4-20mA standard analog signal output and field indication. Accumulation, digital communication, on-site modification of measurement parameters, different power supply functions, with magnetic filters and special specifications. Widely used in petroleum, chemical, power generation, pharmaceutical, food, water treatment, etc. Small diameter metal rotor flowmeter is a kind of variable area flow measurement instrument commonly used in industrial automation process control. It has the characteristics of small size, large detection range and convenient use. It can be used to measure the flow of corrosive gases, especially suitable for medium flow measurement with low flow rate and small flow. Precautions for installation of small-diameter metal rotor flowmeter: 1. It must be installed vertically on a pipeline without vibration. The fluid flows through the flowmeter from bottom to top, and the verticality is better than 2°, the horizontal angle is better than 2 when installed horizontally°; 2. In order to facilitate maintenance and replacement of flowmeters and cleaning of measuring pipes, bypass pipes and bypass valves should be installed on small-diameter metal rotor flowmeters installed on process pipelines; 3. The length of the inlet should be more than 5 times the pipe diameter. 4. If the medium contains ferromagnetic substances, a magnetic filter should be installed; if the medium contains solid impurities, a filter should be installed between the valve and the straight pipe section; 5. When it is used for gas measurement, it should ensure that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter, so that the float can work stably; The flanges are coaxial and parallel to each other, the pipeline is supported to avoid pipeline vibration and reduce the axial load of the flowmeter. The control valve in the measurement system should be installed downstream of the flowmeter: 7. When measuring gas, if the gas is directly at the outlet of the flowmeter To discharge the atmosphere, a valve should be installed at the outlet of the instrument, otherwise the air pressure drop at the float will cause data distortion. 8. When installing a PTFE-lined instrument, the flange nut should not be tightened asymmetrically too tightly, so as not to cause the deformation of the PTFE lining; For meters powered by lithium batteries, try to avoid direct sunlight and high temperature environments (≥65℃) so as not to reduce the capacity and life of the lithium battery The above is the entire content of this article.
