LCD Display Flange Type Level Transmitter Explosion Proof For Remote Monitoring

A level transmitter is a widely used measuring instrument in industrial automation. It is used to measure the height or volume of liquids and convert the liquid level signal into standard electrical signals (such as 4-20mA, 0-5V, etc.) for output, facilitating remote monitoring and automatic control.

1. Immersion type liquid level transmitter: Directly immersed in the liquid, it measures the liquid level through static pressure and is suitable for water towers, water tanks, sewage treatment, etc.
2. Flange type liquid level transmitter: Connected to the container through a flange, it is suitable for high-temperature, high-pressure or corrosive media.
3. Ultrasonic/radar liquid level transmitter: Non-contact measurement, suitable for volatile, viscous or liquid containing solid particles.
4. Float type liquid level transmitter: Utilizing the mechanical displacement of the float, it is suitable for large storage tanks or simple liquid level control.

1. Petrochemical industry: Storage tank liquid level monitoring, reactor liquid level control.
2. Power industry: Boiler drum water level monitoring, cooling water system liquid level control.
3. Water treatment and environmental protection: Sewage treatment tank, drinking water reservoir liquid level monitoring.
4. Food and pharmaceuticals: Hygienic liquid level measurement, in compliance with hygiene standards.
5. Warehousing and logistics: Liquid storage tank, transport vehicle liquid level monitoring.

• Measured medium: Select material and type (such as anti-corrosion type, high-temperature type) based on the properties of the liquid (such as corrosiveness, viscosity, temperature).
• Measuring range: Choose the range based on the height of the container and the range of liquid level changes to avoid being too large or too small.
• Accuracy requirement: Generally, 0.5%FS is selected for industrial applications, and 0.1%FS or higher is selected for precise measurement.
• Environmental conditions: Select models with Exia/Exd certification for explosion-proof areas, and pay attention to the temperature range for high-temperature/low-temperature scenarios.
• Output signal: 4-20mA (two-wire system) is the most commonly used, and models supporting HART or RS485 protocols are more convenient for integration. .
