Level Instruments Frequently Asked Questions
Q: What maintenance do Level Instruments require?
A: Most Level Instruments require minimal maintenance. Ultrasonic sensors may need periodic cleaning of the transducer face. Radar devices generally only require verification checks. For hydrostatic sensors, diaphragm inspection every 6-12 months is recommended. All instruments should have their calibration verified annually under normal operating conditions.
Q: Can Level Instruments be used in hazardous areas?
A: Yes, many of our Level Instruments carry ATEX and IECEx certifications for use in explosive atmospheres. The specific zone classification varies by model and sensor technology. For example, our intrinsically safe LI-200 series is approved for Zone 0 applications, while the LI-300 with flameproof enclosure is suitable for Zone 1 areas. Always verify the certification matches your specific hazardous area classification.
Q: How do I choose between different Level Instrument technologies?
A: Selection depends on multiple factors: ultrasonic works well for non-contact measurement in open vessels; radar excels in applications with vapor or dust; capacitance is ideal for conductive liquids and interface detection; hydrostatic provides excellent accuracy in deep tank applications. Process temperature, pressure, medium characteristics, and required accuracy all influence the optimal technology choice.
