FV4 Series Flow Sensors help identify increasing or decreasing flow in gas systems. The snap-action float provides positive actuation for accurate sensing.
Pressure Gauges
Swagelok gauges provide accurate pressure measurement for industrial, ultrahigh-purity, and sanitary applications. They are offered in a wide range of pressure ranges, dial sizes, connections, mountings, and options to support a wide range of customer requirements.
Pressure Transducers
Swagelok pressure transducers provide accurate electronic pressure monitoring for industrial applications. Transducers are offered in a wide range of pressure ranges, process connections, electrical connectors, and output signals to support a wide range of customer requirements.
Thermometers, Dampened-Movement Bimetal Thermometers
Swagelok thermometers are actuated by a bimetal helix coil. Silicone-free gel inserts dampen vibration effects, and cases are hermetically sealed in accordance with ASME B40.200 to prevent fogging and moisture damage to internal components.
Thermowells
Thermowells are recommended to protect Swagelok dampened-movement bimetal thermometers from damage that could result from contact with pressurized, corrosive, flowing, viscous, or abrasive process fluids. They also enable removal of thermometers for replacement or service without affecting the process or system.
Tube Adapter Pressure Gauges
Swagelok tube adapters can help eliminate difficult alignment problems and can be used with any Swagelok tube fitting. When installing a gauge with a pipe fitting end connection, it is often difficult to align the dial to the desired position without damaging the gauge.
Variable Area Flowmeters
Swagelok variable area flowmeters measure the flow rate of liquids and gases to help you maintain stable fluid flow for process accuracy.
