丙烯酸在精细化工领域占有相当重要的地位。用丙烯酸生产的聚丙烯和丙烯酸共聚物，被用作分散剂、絮凝剂和增稠剂等。到7年代后期，聚丙烯和丙烯酸共聚物又应用于高吸水树脂和助洗涤剂。特性与危害甲基丙烯酸的侵入途径：吸入、食入、经皮吸收。健康危害：本品对鼻、喉有刺激性；高浓度接触可能引起肺部改变。对皮肤有刺激性，可致灼伤。眼接触可致灼伤，造成性损害。慢性影响：可能引起肺、肝、肾损害。对皮肤有致敏性，致敏后，即使接触极低水平的本品，也能引起皮肤刺痒和皮疹。

为了防止衬里变形，我们一般采取以下措施：增加法兰和线圈盒之间的隔热厚度，降低流体温差减小热扩散，使衬里内外温差大程度上得到改善，这样就可以降低渗透率减缓测量管壁内蒸汽的凝聚；此外，将聚四氟乙烯衬里厚度加厚或者更换另外形式的衬里。部电磁的干扰在生产现场存在着管道杂散电流、静电、电磁波和磁场等干扰源。电磁流量计的流量信号很小，非常容易被外界电磁干扰，而影响了电磁流量计的正常工作。所谓的电场干扰是指，流量计测量管内的电势平衡被噪声破坏后出现输出信号波动异常。
