产品简介 
BF、BFN型系列防腐不锈钢膜片压力表,主要用于化学、石油、纺织工业中对气体、液体微小压
力的测量,尤其适用于腐蚀性强、粘稠介质(非凝固非结晶)的微小压力测量。并可根据不同的测量介质选用不同材料的膜片。
 
PRODUCT  OVERVIEW
BF/BFN type Stainless Steel Corrosion-Proof Diaphragm Gauges are built for measuring
low pressure of gas or liquid in chemical , petroleum, textile industries, where strong
corrosion and viscous media ( non-crystallized ) are a concern. Different diaphragm
materials are available to be compatible with process fluids.
