Chemical and petrochemical systems require solutions that follow strict industry standards so they can operate safely and efficiently, regardless of process demands.

Acid Leak
Use assemblies with acid leak detection to prevent dangerous chemicals from damaging your instruments and your process.

Over Pressure
Choose an accessory such as a pressure limiting valve to prevent to minimize equipment damage if over pressure occurs.

Excessive Vibration and Pulsation
Opt for gauges with liquid fill or dampening movement technology to stabilize the pointer or eliminate movement altogether in harsh conditions.

Extreme Temperatures
Select accessories like a finned siphon for better heat dissipation or a capillary line that eliminates direct contact between instrument and process connection.

Material Compatibility
Ensure wetted materials are compatible with the process media to prevent instrument failure. If they are, use a diaphragm seal.
