Visual level

Product catalog summary
Overview: The document provides comprehensive details on visual level gauges, specifically the TL and LV/M series, designed for precise liquid level monitoring in tanks. These gauges utilize the principle of communicating vessels and offer options for electrical signaling and temperature monitoring.
Specifications and Features:
  • Visual Level Gauges (TL Series): These gauges use communicating vessels to display liquid levels, available in center-to-center (C/C) distances of 76, 127, and 254 mm. They are constructed from transparent polyamide or polycarbonate, ensuring constant visibility and high mechanical strength.
  • Electrical Characteristics: The TL/E series combines visual and electrical signals, insulating electrical components from the liquid for safety.
  • Temperature Monitoring: Options include bimetallic thermometers and PT100 sensors, with metal plates to enhance heat conduction.
  • Customizable Options: Gauges can be customized with taps, interchangeable C/C distances (127 to 4000 mm), and "U" protection screens for adjustable visibility.
Operational Principles: The gauges operate using hollow screws that allow liquid passage, displaying the exact tank level. Some models feature floats with magnets for additional signaling capabilities.
Advanced Features:
  • Minimum and Maximum Level Signals: Models like LV/E1 and LV/E2 provide signals for minimum and maximum levels, with options for normally open (N.O.), normally closed (N.C.), or exchange contacts.
  • Variable Position Sensors: The LV/E-S series includes sensors that can be positioned along the gauge axis for flexible monitoring.
Technical Advantages: These gauges offer continuous level indication, robust design requiring minimal protection, and chemical resistance due to polyamide 12.
Installation and Safety: Designed for easy installation with recessed screws and standard industrial connectors (IP 65 PG7), ensuring safety by separating electrical components from the liquid.
LV/M Series Overview: These indicators consistently monitor liquid levels using a transparent tube, operating on the principle of communicating vessels.
Principle of Operation: Liquid flows through a hollow transparent tube, revealing the tank's liquid level, attached via screws.
Options:
  • Interchangeable C/C distances of 76, 127, and 254 mm.
  • Various polymeric materials for tubes, blocks, and O-rings.
  • Stainless steel AISI 316 for metallic parts in contact with liquid.
Technical Advantages:
  • Continuous liquid level indication.
  • Shock protection with "U" profile anodized aluminum.
  • Flexibility for correcting implementation defects.
  • Electrical signal capability via a bistable sensor.
Specifications:
  • Maximum tightening torque: 10 Nm.
  • Electrical characteristics: 40 W/40 VA power, 2 A current, 230 VDC/VAC voltage.
Use Cases: Suitable for hydraulic power packs and tanks with water, diesel oil, and mineral oils (viscosity ≤ 220 cSt), excluding acids or flammable substances.
Additional Features:
  • Available in nylon fiberglass reinforced, anodized aluminum, or stainless steel AISI 316.
  • Tubes in acrylic or pyrex glass.
  • Optional bimetallic thermometer probe (0 to 120°C).
Electromagnetic Control: Describes electromagnetic level gauges for signaling or activating/disconnecting circuits, suitable for similar applications as visual indicators, with minimum and maximum level contacts.
Visual Level Gauge Characteristics:
  • Incorporated in the connection block with options for minimum, maximum, or both level indicators.
  • Adjustable connector position for optimal wire connection.
  • Available in methacrylate or pyrex glass with nickel-plated brass or AISI 316 stainless steel fittings.
