Flow meter working characteristics description

Flow meter working characteristics
· The instrument should be able to withstand the effects of chemical corrosion, scale abrasion, clogging, phase change, temperature resistance, pressure resistance, etc. of the measured medium.
· Due to the integration of the instrument and the pipeline, it is difficult to disassemble and replace the valve. Especially for high temperature and high pressure large diameter pipes, the cycle inspection is very difficult.
· For the continuous production process, the intermediate stop flow is not allowed to be disassembled, and the fault of the test piece cannot be overhauled. How to deal with it is a difficult problem.
· Due to the backward process of the equipment, poor management, serious contamination of the fluid medium, and the use of higher PDF files for the use of performance "pdf Fact o "V P "o" trial version creation requirements.
To improve the reliability of the instrument, you can take the following measures:
· Improve the quality of the instrument;
· Change the structure form. If you use the continuous flow plug-in structure, you can also find a way on the measurement system, such as multi-tube parallel pipe to facilitate the replacement and cleaning of the test piece;
· Strengthen on-site maintenance management.
The accuracy of the flow measurement involves the problem of the flow rate value transfer. Here we need to distinguish the technical indicators commonly used by the two instruments: repeatability and accuracy. Repeatability is the characteristic of the meter itself, it depends on the working principle and manufacturing quality of the meter, and the accuracy is an additional characteristic, which is determined in the calibration system. A flow meter is a meter whose meter performance is strongly dependent on the conditions of use. An internationally renowned traffic expert said that the flowmeter is one of the most difficult steps to use than the manufacturing. In the laboratory, it can get extremely high precision, but once the conditions change, everything is white. Waste. In particular, various high-precision instruments such as electromagnetic flowmeters, vortex flowmeters, orifice flowmeters, etc., are more demanding on the environment.
