A level transmitter is an industrial sensor used to continuously measure the level of liquids or solids in tanks, containers, or open environments. It works by converting pressure, hydrostatic force, or ultrasonic signals into standardized output signals such as 4–20mA or HART for monitoring and control systems.
Common types of level transmitters include submersible level sensors, differential pressure level transmitters, radar level transmitters, and capacitive level sensors. Different models are selected based on liquid type, temperature, pressure conditions, and installation environment.
A level transmitter measures liquid height or level in a container, while a pressure transmitter measures force exerted by a fluid or gas. However, many industrial level transmitters use pressure-based principles to calculate liquid level indirectly.
Industrial level transmitters are widely used in water treatment systems, oil and gas storage tanks, chemical processing plants, food and beverage production, HVAC systems, and hydraulic equipment.
Yes. Depending on the material selection (such as stainless steel 316L or ceramic diaphragms), level transmitters can be used for corrosive, high-temperature, or high-pressure environments.
Most industrial level transmitters support 4–20mA analog output, 0–10V, and digital communication protocols such as HART or Modbus, making them compatible with PLC and automation systems.
Selection depends on measuring range, medium type, temperature, pressure, installation method, and required output signal. For complex applications, OEM customization is often recommended.
Yes, OEM customization is available, including measuring range, housing material, cable length, output signal, and process connection types to meet specific industrial requirements.
