FAQ – E&H Level Transmitter

Q1. What is an E&H Level Transmitter?

An E&H (Endress+Hauser) Level Transmitter is an industrial instrument designed to measure and monitor liquid or bulk solid levels in tanks, vessels, and open basins. It converts the measured value into an electrical signal for process control and automation.

Q2. What measurement principles are available?

E&H offers multiple technologies, including:

1. Hydrostatic (submersible probes)
2. Differential pressure
3. Radar (non-contact FMCW)
4. Ultrasonic (non-contact)
5. Capacitance
6. Radiometric (gamma-based)

Q3. Which industries use E&H Level Transmitters?

They are widely applied in water & wastewater, chemical, oil & gas, food & beverage, pharmaceuticals, power generation, and mining.

Q4. How do I choose the right model?

Selection depends on:

1. Medium type (liquid, slurry, bulk solid)
2. Tank geometry and installation conditions
3. Temperature and pressure ranges
4. Required accuracy and safety standards (e.g., SIL certification)

Q5. What communication protocols are supported?

Most E&H transmitters support HART, Profibus PA, Foundation Fieldbus, and Modbus. Newer radar models also support Ethernet-APL and wireless options.

Q6. Are E&H Level Transmitters suitable for hazardous areas?

Yes. Many models are ATEX, IECEx, and FM/CSA certified for use in explosive atmospheres.

Q7. What is the typical accuracy?

1. Radar: up to ±1 mm
2. Hydrostatic: ±0.1% of span
3. Differential pressure: ±0.075% of span
4. Ultrasonic: ±3–5 mm (depending on range)

Q8. Do they require regular maintenance?

Non-contact radar and ultrasonic transmitters are virtually maintenance-free. Hydrostatic and differential pressure devices may require periodic calibration and inspection depending on process conditions.

Q9. Can they integrate with automation systems?

Yes. They are designed for seamless integration into DCS, PLC, and SCADA systems, with advanced diagnostics and asset management features.

Q10. What support does E&H provide?

Endress+Hauser offers global technical support, calibration services, and lifecycle management tools to ensure long-term reliability.
