Measurement Principles

• Magnetic transmission (By-pass magnetic level gauges) Based on the communicating vessels principle with a float and magnetic coupling for external indication. Provides complete hermetic sealing with no risk of leakage.

• Vibrating level switches Vibrating fork technology for point level detection of liquids and solids. Compact design, no moving parts, highly resistant to pressure and temperature.

• Ultrasonic Non-contact measurement using ultrasonic waves. Suitable for liquids, powders, and granules.

• Radar (Radar / Guided radar) Non-contact or guided microwave radar for accurate level measurement of liquids and solids, even in difficult conditions.

• Float type (Mechanical with contacts) Mechanical level indicators with floats, signal contacts, and transmitters.

• Displacer Level measurement based on the displacer (buoyancy) principle.

Series

• Series LT — By-pass magnetic level gauges with visual indication via magnetic flags or scale. Available with 4-20 mA transmitters and control contacts. Materials: stainless steel, PVC, PP, PVDF, PTFE. Suitable for high pressure and temperature (up to 400°C in stainless steel versions).

• Series LC / LC40 — Float type level indicators and switches with up to 6 signal contacts. Mechanical operation for various liquids.

• Series LE — Float type level transmitters and indicators with continuous measurement and visual display.

• Series LP — Displacer type level transmitters. Provide accurate continuous level measurement with 4-20 mA output (HART / Modbus options). Ideal for storage tanks, food industry, and toxic liquids.

• Series LD — Vibrating fork level switches for liquids and bulk solids. Compact, reliable, no moving parts, excellent resistance to pressure and temperature.

• Series LS / LTL — Magnetic level indicators with additional automation options.

• Series LU — Ultrasonic level transmitters and indicators. Compact design with digital output and optional remote display. Suitable for chemicals, water, wastewater, and silos.

• Series LR / LTDR — Radar level transmitters (including guided radar). Non-contact measurement for liquids and solids, with option for remote display.

• Other models (e.g. NPC) — Additional point level controls and accessories.

Main Application Areas

• Chemical and petrochemical industry

• Water and wastewater treatment

• Food and beverage industry

• Pharmaceutical industry

• Marine and shipbuilding (including naval applications)

• Boilers, steam systems, and heating/cooling installations

• Storage tanks for fuels, chemicals, and bulk materials

• Process industry with aggressive, toxic, or viscous media

Key Advantages of TECFLUID Level Equipment

• High reliability and long service life (over 40–50 years of manufacturing experience).

• Excellent resistance to extreme conditions — high pressure, high temperature (up to 400°C), aggressive and corrosive media thanks to wide material selection (AISI 316L, PVC, PP, PTFE, PVDF, etc.).

• Superior safety and hermetic sealing, especially in magnetic by-pass models (no leakage risk).

• Simple installation and low maintenance — mechanical versions require no power supply; vibrating forks have no moving parts.

• High versatility — combination of visual indication, alarm contacts, and electronic transmitters (4-20 mA, HART, Modbus).

• Compact design and easy integration into complex installations.

• Compliance with industrial standards, including ATEX for hazardous areas and hygienic requirements.
