1. How to calculate the testing cycle of industrial flow meters?
The testing cycle of industrial flow meters needs to be comprehensively judged based on regulatory standards, usage scenarios, and equipment conditions. The core conclusions are as follows:
1. Regulatory standards are the core. Specific requirements for flow meters for specific purposes are mandatory by the country or industry. For example, liquid flow meters used for trade settlement are usually required to be calibrated once every 1-3 years. The specific implementation is based on the "Catalogue of Work Measuring Instruments for Compulsory Calibration" in the region.
2. The product manual provides a basic cycle. The manufacturer will provide testing recommendations based on product performance.
. For example, a certain electromagnetic flowmeter is marked to undergo a comprehensive inspection every 2 years, which is suitable for normal working conditions and has no abnormalities. This cycle can be referr
3. Use scenario: Dynamic Li cracking state affects the cycle. • High frequency use: The detection cycle of a flowmeter that runs continuously for 24 hours needs to be shortened by about 50% compared to intermittent use. Special medium scenarios: When measuring highly corrosive media (such as concentrated sulfuric acid) or fluids containing particles, it may be necessary to conduct testing every six months. • Adverse environmental scenarios: high temperature (such as furnace equipment), strong vibration, etc. It is recommended to test at least once a year.
4. Historical calibration data determines the elasticity of the cycle. If the detection error is less than 0.5% for three consecutive times, an extension of 10% -20% of the original cycle can be applied for; If the single error exceeds 2%, immediate re inspection is required and the subsequent cycle should be shortened.
