本公司 常用差压变送器根据以下几点选型：

1、测量范围、需要的精度及测量功能；

2、测量仪表面对的环境，如石油化工的工业环境，有可燃（有毒）和爆炸危险气氛的存在，有较高的环境温度等；

3、被测介质的物理化学性质和状态，如强酸、强碱、粘稠、易凝固结晶和气化等工况；

4、操作条件的变化，如介质温度、压力、浓度的变化。有时还要考虑到从开车到参数达到正常生产时，气相和液相浓度和密度的变化；

5、被测对象容器的结构、形状、尺寸、容器内的设备附件及各种进出口料管口都要考虑，如塔、溶液槽、反应器、锅炉汽包、立罐、球罐等；

6、其他要求，如环保及卫生等要求；

7、工程仪表选型要有统一的考虑，要求尽可能地减少品种规格，减少备品备件，以利管理；

8、工艺商的具体要求。

9、实际的工艺情况：

1）考虑被测对象是属于哪一类设备。如槽、罐类，槽的容积较小，测量范围不会太大，罐的容积较大，测量范围可能较大；

2）要看介质的物化性质及洁净程度，常规的差压式变送器及浮筒式液位变送器，还要对接触介质部分的材质进行选择；

3）对有些悬浮物、泡沫等介质可用单法兰式差压变送器。有些易析出、易结晶的用插入式双法兰式差压变送器；

4）对高黏度的介质的液位及高压设备的液位，由于设备无法开孔，可选用放射液位计来测量；[4]

5）除了测量方法上和技术上问题外，还有仪表投资问题。

综上所述，变送器的选型，从技术上要可行，经济上要合理，管理上要方便。

在诸类仪表中，变送器的应用广泛、普遍，变送器大体分为压力变送器和差压变送器。变送器常用来测量压力、差压、真空、液位、流量和密度等。变送器有两线制和四线制之分，两线制变送器尤多；有智能和非智能之分，智能变送器渐多；有气动和电动之分，电动变送器居多；另外，按应用场合有本安型和隔爆型之分；按应用工况变送器的主要种类如下：

低（微）压/低差压变送器；

中压/中差压变送器；

高压/高差压变送器；

绝压/真空/负压差压变送器；

高温/压力、差压变送器；

耐腐蚀/压力、差压变送器；

易结晶/压力、差压变送器
