Notes
- We suggest to install tri-valve between the measured point and transmitter to protect the media adding on transmitter’s positive and negative cavities slowly;
- We suggest to make two pressure ports horizontally to reduce installation direction effect;
- Please pay attention that the static pressure should be less than 200bar, transmitter positive and negative cavity should be in the rating pressure range;
- Please note ex-proof, M6 or M7 options in the order if the user needs ;
- Digital indicator information, please refer to MPM4901FL datasheet;
- If the user has special requirement, please feel free to contact our
