Diaphragm Flange Pressure Gauge

Diaphragm Flange Pressure Gauge is a robust industrial instrument using a flexible diaphragm within a flanged housing to measure fluid pressure, ideal for tough conditions like highly viscous, corrosive, or crystallizing media, protecting the internal mechanism by separating it from the process fluid, offering a reliable, system-fill-free alternative to standard gauges for critical applications in chemical, oil, and power industries.

Product Description

Key Features & Function:

Diaphragm Element: A sensitive, elastic diaphragm (often stainless steel, sometimes PTFE-lined) deflects under fluid pressure.
Flanged Connection: The diaphragm sits between upper and lower flanges, providing a secure, leak-proof, and often open connection to the process, preventing blockage.
Direct Drive: A pushrod directly links the diaphragm's movement to the gauge's pointer, eliminating the need for liquid fills.
Media Protection: Shields the gauge's internal works from aggressive, sticky, or crystallizing substances.
Applications: Chemical, petrochemical, oil & gas, power generation, sewage, heavy oil.

Advantages:

Superior for Harsh Media: Handles viscous, corrosive, hot, or solidifying fluids where standard gauges fail.
High Overload Protection: Can withstand significant pressure spikes without damage.
Easy Mounting: Flange design allows for simple, direct installation on pipelines.
No System Fill Required: More reliable and simpler than diaphragm seals that use fill fluids.
