How to choose a metal rotor flow meter?

Abstract: How to choose a metal rotor flow meter? The information is provided by the excellent flow meter and flow meter production and quotation manufacturers. Metal rotor flowmeter is suitable for small diameter and low flow rate medium flow measurement; reliable operation, low maintenance, long life; low requirements for straight pipe sections; wide flow ratio of 10:1; double-line large liquid crystal display, optional on-site Instantaneous/cumulative flow display, available. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is how to choose a metal rotor flowmeter? The article details. Metal rotor flowmeter is suitable for small diameter and low flow rate medium flow measurement; reliable operation, low maintenance, long life; low requirements for straight pipe sections; wide flow ratio of 10:1; double-line large liquid crystal display, optional on-site Instantaneous/cumulative flow display, with single-axis sensitive indication with backlight; non-contact magnetic coupling transmission; metal rotor flowmeter with all-metal structure, suitable for high temperature, high pressure and strong corrosive media; can be used in flammable and explosive hazardous situations; Choose two-wire system, battery, AC power supply mode; multi-parameter calibration function; metal rotor flowmeter with data recovery, data backup and power-down protection functions. How to choose a metal rotor flowmeter? 1. The most suitable installation method is vertical installation from bottom to top. 2. When measuring high temperature and low temperature (below -30℃) medium, it is best to use the jacket type. 3. It is not suitable for measuring the medium with large density change. 4. It is not suitable for measuring the flow of pulsating medium (such as the outlet of the metering pump). 5. For gas, this watch has no temperature and pressure compensation, and needs to be considered separately. 6. For the intensive installation of multiple instruments or the carbon steel process pipeline passing near the instrument, keep a distance of more than 100mm from the instrument to avoid magnetic field interference. 7. When measuring the flow of medium containing a large number of ferromagnetic particles, a magnetic filter should be installed in front of the instrument and purged regularly. 8. The metal rotameter does not have high requirements for the straight pipe section, generally 250mm before and after 5D. 9. If the instrument is used in explosion-proof occasions, the round shell M4 indicator should be selected. 10. The high and low alarms of the flowmeter are generally open-collector OC gate mode, and an external relay is required to amplify the current. The relay output type can also be selected. The contact capacity is 1A30VDC or 0.25A250VAC or 0.5A125VAC11. Measurement of steam flow. 12. Magnetic coupling principle, no leakage and high pressure resistance. 13. High temperature resistance, up to 450℃. 14. Affected by a certain viscosity, it is not suitable to measure high-viscosity medium. 15. When the flow exceeds 100m3/h water flow, the pressure loss is large. 16. It is mostly used for process control instruments. The best accuracy is 1%, generally 1.5%, and the range ratio is 10:1. 17. There are all intrinsically safe explosion-proof and explosion-proof types, which are suitable for dangerous occasions. 18. There are various forms such as local pointer type, battery type, two-wire type, and 220V AC power supply type to choose from. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'How to choose a metal rotor flow meter?'
