جهاز إرسال المستوى العائم لقياس موثوق به لمستوى السائل

The float level transmitter is a reliable and accurate level measurement instrument designed for continuous liquid level monitoring in industrial tanks, vessels, and process systems. By detecting liquid level changes through the movement of a float, the float level transmitter converts the mechanical displacement into a stable electrical output signal for process control and monitoring.

Float level transmitters are widely used due to their simple structure, stable performance, and adaptability to various liquids. With different material options and output signals, the float level transmitter is suitable for industrial applications requiring dependable level measurement under demanding operating conditions.

صهاريج تخزين النفط والوقود
Power generation facilities
Process control systems

The robust design of float level transmitters ensures reliable operation in both indoor and outdoor industrial applications.

Working Principle of Float Level Transmitter

The float level transmitter consists of two main parts: the level measuring mechanism and the electrical transmission unit (meter head).

The level measuring mechanism includes a measuring float, float rod, balance hammer, and balance rod. These components form a torque balance system, allowing the float to move freely up and down in response to changes in the liquid level.

When the liquid level rises or falls, the float moves accordingly and drives the main shaft to rotate. The main shaft is axially connected to the angular displacement sensor located in the meter head, forming a synchronized mechanical transmission system.

As the main shaft rotates, the angular displacement sensor converts the shaft’s angular movement into an electrical signal. The electronic circuit inside the meter head then processes this signal and outputs a standard 4–20 mA current signal that is directly proportional to the actual liquid level.

This design ensures accurate, stable, and continuous level measurement under normal operating conditions.

Float Type Level Transmitter Structural Composition

A typical float level transmitter consists of:

Float (stainless steel or plastic)
Guide rod or stem
Level sensing element
Transmitter housing
Electrical connection interface
Process mounting (flange or thread)

The compact and modular structure enables easy installation and flexible customization.

What is a float level transmitter used for?

A float level transmitter is used for continuous liquid level measurement in industrial tanks, vessels, and process systems. It converts the movement of a float into an electrical output signal for monitoring and process control.

How does a float level transmitter work?

A float level transmitter works based on the buoyancy principle. As the liquid level changes, the float moves up or down and transfers the movement to a sensing element, which converts it into an electrical signal such as 4–20 mA.

What types of liquids can a float level transmitter measure?

Float level transmitters can measure a wide range of liquids, including water, oils, fuels, chemicals, and other industrial fluids, provided the liquid density and material compatibility are suitable for the float and stem materials.

What output signals are available for float level transmitters?

Common output signals for float level transmitters include 4–20 mA, 0–10 V, and switch outputs. Customized signal options are also available to meet specific control system requirements.

Can float level transmitters be customized?

Yes. Float level transmitters can be customized in terms of measuring range, probe length, material selection, mounting type, output signal, and protection level to match different tank sizes and process conditions.

Are float level transmitters suitable for harsh industrial environments?

Float level transmitters are designed for industrial use and can operate under high temperature, pressure, and corrosive conditions when proper materials and sealing options are selected. They are widely used in chemical, oil & gas, and power generation industries.
