Flow Instrument Comparison

Compare Endress+Hauser flow technologies based on media type, accuracy, installation and diagnostics.

Promag vs Promass

• Promag (Electromagnetic): Conductive liquids, water, wastewater, slurries.
• Promass (Coriolis): Mass flow, density, viscous liquids, entrained gas.
• Key Difference: Promag requires conductivity; Promass does not.

Prowirl vs T-Mass

• Prowirl (Vortex): Steam, compressed air, industrial gases.
• T-Mass (Thermal): Direct mass flow for air and gases.
• Key Difference: Prowirl handles steam; T-Mass handles dry gases.

Ultrasonic vs Electromagnetic

• Ultrasonic: Non-intrusive, large pipes, clean liquids.
• Electromagnetic: Conductive liquids, slurry, wastewater.
• Key Difference: Ultrasonic is clamp-on; Promag is inline.

Level Instrument Comparison

Compare radar, guided wave radar, ultrasonic and vibration level technologies.

Micropilot vs Levelflex

• Micropilot (Radar): Liquids, slurries, solids, vapour-resistant.
• Levelflex (GWR): Interface measurement, tall vessels, low dielectric media.
• Key Difference: Levelflex handles interface measurement better.

Ultrasonic vs Radar

• Ultrasonic: Water, wastewater, open channels.
• Radar: Harsh conditions, vapour, foam, solids.
• Key Difference: Radar is immune to vapour and foam.

Liquiphant vs Liquicap

• Liquiphant (Vibration): Pump protection, overfill prevention.
• Liquicap (Capacitance): Solids, powders, granular media.
• Key Difference: Liquiphant is for liquids; Liquicap is for solids.

Pressure Instrument Comparison

Compare ceramic vs metallic cells, DP vs gauge, and remote seal configurations.

Cerabar vs Deltabar

• Cerabar: Gauge & absolute pressure.
• Deltabar: Differential pressure.
• Key Difference: Deltabar is used for DP flow and pressurised tank level.

Ceramic vs Metallic Sensor Cells

• Ceramic: Abrasive, corrosive media.
• Metallic: High pressure, high temperature.
• Key Difference: Ceramic is more chemically resistant.

Remote Seal vs Direct Mount

• Remote Seal: Hot, viscous, corrosive media.
• Direct Mount: Standard process conditions.
• Key Difference: Remote seals isolate the sensor from harsh media.

Temperature Instrument Comparison

Compare RTDs, thermocouples and transmitter configurations.

RTD vs Thermocouple

• RTD: High accuracy, stability, hygienic applications.
• Thermocouple: High-temperature furnaces, boilers.
• Key Difference: RTDs are more accurate; thermocouples handle higher temperatures.

Head Transmitter vs DIN Rail

• Head Transmitter: Mounted in sensor head.
• DIN Rail: Centralised control panel installation.
• Key Difference: Head transmitters reduce noise and wiring length.

Analytical Instrument Comparison

Compare pH, conductivity, turbidity and dissolved oxygen sensors.

Memosens vs Analog Sensors

• Memosens: Digital, drift-resistant, safer calibration.
• Analog: Lower cost, higher maintenance.
• Key Difference: Memosens eliminates moisture ingress issues.

Inductive vs Conductive Conductivity

• Inductive: High-conductivity, fouling media.
• Conductive: Low-conductivity applications.
• Key Difference: Inductive sensors resist fouling better.

Optical vs Electrochemical DO

• Optical: Low maintenance, stable.
• Electrochemical: Higher maintenance.
• Key Difference: Optical DO reduces calibration frequency.
