Process Monitoring — Flow, Pressure, Level & Temperature
Select the measurement principle around the medium, range, pressure, temperature, process connection and required output. The strongest process-monitoring architecture starts with the process condition—not with a preferred sensor family.
FlowPressureLevelTemperature
Four core measurements
Build the process view around what actually needs to be controlled
Flow, pressure, level and temperature often interact; one process may require several sensor families rather than a single multi-purpose device.
Pressure & Vacuum
Industrial and hygienic pressure sensing spans switching, transmitter and display-based architectures with different measuring cells and ranges.
Point & Continuous Level
Choose point-level, guided-wave radar, free-space radar, capacitive or hydrostatic routes according to medium, tank and process conditions.
Explore continuous level sensing →Temperature
RTD-based transmitters and display sensors are selected by range, probe, process connection, response and output architecture.
Process applications
Typical monitoring points across machines and plant
The correct sensor family changes with medium and purpose.
Cooling circuits
Flow, pressure and temperature jointly indicate whether a machine or process is receiving effective cooling.
Hydraulic systems
Pressure and temperature monitor power-unit condition; level can supervise reservoirs.
Tank & vessel monitoring
Point or continuous level is selected around tank geometry, medium, foam, agitation, pressure and hygienic requirements.
Pump protection
Flow/no-flow and level sensing help prevent dry running and loss of process supply.
Compressed-air consumption
Dedicated SD meters support consumption, leakage and utility-allocation analysis.
Food & beverage
Hygienic pressure, level, flow and temperature devices must be selected around process connections, cleaning and media conditions.

IO-Link can expose more than the primary process value
Current ifm IO-Link process sensors cover pressure, flow, level and temperature. Depending on the device, one connection can provide process values, parameterisation, status information and additional measured variables.
Parameter backupSimplifies replacement and repeatable commissioning where supported by the architecture.
Additional valuesSome devices provide temperature, pressure, totaliser or secondary values beyond the primary measurement.
DiagnosticsDevice-specific event and status information can improve troubleshooting.
Digital transmissionTransfer process values digitally without analogue conversion losses.
Selection logic
Select the measurement principle before the order number
A sensor family that fits one medium can be wrong for another.
