Micropilot M FMR60

Summary

Product identification

The Micropilot FMR60 is a free space radar level measurement instrument.

Application

• Continuous, non-contact level measurement of liquids, pastes, and sludges.
• Features a PTFE drip-off antenna.

Operating limits

• Maximum measuring range: 50 m (164 ft)
• Process temperature: –40 to +130 °C (–40 to +266 °F)
• Process pressure: –1 to +16 bar (–14.5 to +232 psi)
• Ambient temperature range (Measuring device): –40 to +80 °C (–40 to +176 °F)
• Ambient temperature range (Local display): –20 to +70 °C (–4 to +158 °F)
• Storage temperature: –40 to +80 °C (–40 to +176 °F)

Performance characteristics

• Accuracy:
  • Measuring distance up to 0.8 m (2.62 ft): ± 4 mm (±0.16 in) or ±0.03 % (analog)
  • Measuring distance > 0.8 m (2.62 ft): ± 1 mm (±0.04 in) or ±0.02 % (analog)
• Non-repeatability: ≤ 1 mm (0.04 in)
• Measured value resolution (Analog): 1 µA
• Response time: < 3.6 s (with damping switched off, measuring rate ≥ 1.3 s⁻¹ at U ≥ 24 V)
• Influence of ambient temperature:
  • Digital (HART): average TC = 2 mm/10 K
  • Analog (current output): Zero point (4 mA) TC = 0.02 %/10 K, Span (20 mA) TC = 0.05 %/10 K

Feed water

• Dielectric constant (εr): ≥ 1.9 for liquids.
• Minimum level for low dielectric constants (εr ≤ 4): 80 mm (3.15 in) above the bottom of the tank.
