Description

Level Transmitter

The Level Transmitter is an industrial instrumentation device designed for accurate and continuous measurement of liquid or solid material levels in tanks, vessels, silos, and process containers. It detects the level of the process medium and converts the measured value into a standard electrical signal for monitoring, indication, control, and automation systems.

Designed for reliable operation in demanding industrial environments, the Level Transmitter can be used across water treatment, chemical processing, pharmaceutical, food & beverage, oil & gas, power generation, and general process industries. Depending on the application, different sensing technologies and process connections can be selected to suit the medium, tank geometry, pressure, temperature, and measurement range.

Key Features

• Continuous and reliable level measurement
• High accuracy and repeatability
• Suitable for liquids and selected bulk solids
• Compact and rugged industrial construction
• Digital indication options available
• 4–20 mA output for process control
• Optional HART or digital communication
• Wide measurement range options
• Multiple process connection configurations
• Suitable for demanding industrial environments
• Easy integration with PLC, DCS, and SCADA systems
• Low-maintenance operation

Working Principle

The Level Transmitter uses a sensing element to detect the level of the process material inside a tank or vessel. The measured level is processed electronically and converted into a proportional output signal.

Depending on the selected model, level measurement may be based on technologies such as hydrostatic pressure, ultrasonic, radar, capacitance, or other level-sensing principles. The transmitter continuously processes the measurement and provides a standardized signal to connected monitoring and control equipment.

This enables operators to monitor tank levels in real time and maintain accurate control of filling, storage, dosing, and process operations.
