Liquiphant FTL50 - Detailed Overview

Working Principle (Vibronic / Tuning Fork)

The FTL50 features a metal tuning fork continuously excited to vibrate at its natural resonance (~85 Hz)
In air (or gas): the fork vibrates freely at a higher frequency
When liquid covers the fork: vibration is damped, frequency decreases, and electronics detect the shift
Switch changes state (relay or electronic output)
This principle is independent of:
- Conductivity (works in non-conductive oils or conductive water)
- Dielectric constant (not affected by media change)
- Density (works down to ~0.5 g/cm³)
- Viscosity (works up to ~10,000 mm²/s)

Key Features

Compact design - ideal for installation in tight spaces, pipes, and small tanks
No calibration required - plug-and-play solution
Failsafe mode selectable - High (overfill protection) / Low (pump dry-run protection)
Self-monitoring electronics - diagnostic function with NAMUR NE 107 status signal
Wide media compatibility - from water to oils and aggressive chemicals
Maintenance-free - no moving parts, no wear
Safety rated - SIL2/3 certified according to IEC 61508

Technical Specifications

Measuring task: Point level detection in liquids
Process temperature:
- Standard: -40 °C to +150 °C
- Special versions: up to 280 °C
Process pressure: up to 40 bar (580 psi)
Density limit: ≥0.5 g/cm³ (can be used with light hydrocarbons, solvents)
Viscosity range: up to 10,000 mm²/s
Pipe diameter: ≥25 mm
Output options:
- Relay (SPDT)
- PNP/NPN transistor
- 2-wire AC/DC
- NAMUR signal
- Fieldbus (PROFIBUS PA, FOUNDATION Fieldbus)
Ingress protection: IP66/67, NEMA 4X
Explosion protection: ATEX, IECEx, FM, CSA, NEPSI (gas and dust applications)

Applications

Overfill protection in tanks and vessels (safe shutdown)
Dry-run protection for pumps (avoiding damage)
Leak detection in pipelines and containment
Safety-critical loops (SIL-rated shutdown)
Suitable for:
- Water & Wastewater
- Chemical and Petrochemical
- Oil & Gas
- Food & Beverage (hygienic versions available)
- Power Plants
