选型时应考虑的因素
Factors to be considered in model selection
1.测量对象,如被测介质的物理和化学性质,以及工作压力和温度、安装条件、液位变化的速度等。
1. Measuring objects, such as the physical and chemical properties of the measured medium, as well as working pressure and temperature, installation conditions, liquid level change speed, etc.
2.测量和控制要求,如测量范围、测量(或控制)精确度、显示方式、现场指示、远距离指示、与计算机的接口、安全防腐、可靠性及施工方便性。
2. Measurement and control requirements, such as measurement range, measurement (or control) accuracy, display mode, field indication, remote indication, interface with computer, safety and corrosion protection, reliability and construction convenience.
3.还要考虑到磁性材料的退磁问题,退磁导致液位计不能正常工作,测量结果也可能不准。
3. The demagnetization of magnetic materials should also be considered. Demagnetization may cause the level gauge to fail to work normally and the measurement result may be inaccurate
