Mô tả

The DIF-S features a dual-diaphragm structure that allows accurate measurement in lower pressure ranges, making it an ideal solution where traditional “I-section” flange diaphragm seals cannot be installed due to limited space. It is designed for harsh media such as biogas, crude oil, gas-fracking fluids, and biodiesel applications. Compatible with ANSI/ASME, JIS, and DIN2527 flanges, the DIF-S supports both pressure gauges and transmitters, with optional flush ports and metal or PTFE linings for enhanced corrosion resistance and easy maintenance.
