The YYPD536 is a flange-mounted differential pressure transmitter with monocrystalline silicon sensing and HART communication. It covers filter monitoring, liquid level on pressurised tanks and flow measurement across primary elements, with an ultra-high-temperature option to 600 °C.

Flange mounting avoids impulse-line plugging on viscous or crystallising media; impulse piping suits clean fluids at distance.
Yes — DP between bottom flange and gas phase gives true level, compensated for overlay pressure.
