Installation notes for small-caliber metal rotameters:
1. Must be installed vertically on a vibration-free pipe. The fluid flows through the flowmeter from bottom to top, and the verticality is better than 2°, and the horizontal angle is better than 2° when installed horizontally;
2. In order to facilitate the repair and replacement of the flowmeter and the cleaning of the measuring pipeline, the small- diameter metal rotor flowmeter installed on the process pipeline shall be equipped with a bypass pipeline and a bypass valve;
3. There should be a straight pipe section with a length of 5 times or more at the entrance, and the outlet should have a straight pipe section of 250mm;
4. If the medium contains ferromagnetic substances, a magnetic filter should be installed; if the medium contains solid impurities, consider adding a filter between the valve and the straight pipe section;
5. When used for gas measurement, ensure that the pipeline pressure is not less than 5 times the pressure loss of the flowmeter to stabilize the float;
6. In order to avoid the deformation of the flowmeter caused by the pipeline, the flange of the process pipeline must be coaxial with the flange of the flowmeter and parallel to each other. The pipeline support avoids the vibration of the pipeline and reduces the axial load of the flowmeter. The valve should be installed downstream of the flowmeter:
7. When measuring gas, if the gas directly discharges the atmosphere at the outlet of the flowmeter, the valve should be installed at the outlet of the meter, otherwise the air pressure will drop at the float and cause data distortion.
8. When installing the PTFE-lined instrument, do not loosen the flange nut too tightly to avoid deformation of the PTEF lining;
9, with a liquid crystal display instrument, try to avoid direct sunlight display, so as not to reduce the life of the liquid crystal; with lithium battery powered instruments, try to avoid direct sunlight, high temperature environment (≥ 65 ° C) to avoid reducing the capacity of lithium batteries and life
Small-caliber metal rotameter adopts variable area measurement principle. The flowmeter has full metal structure and is internally lined with PTFE material. It is suitable for corrosive gases. It has indicating type, electric remote type, corrosion resistant type, high pressure type and jacket. Type, explosion-proof type. Standard analog signal output with 0-10mA, 4-20mA and on-site 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. The small-diameter metal rotameter is a variable-area flow measuring instrument commonly used in industrial automation process control, and has the characteristics of small volume, large detection range and convenient use. It can be used to measure the flow rate of corrosive gases, especially for medium flow measurement with low flow rate and low flow rate.
