Information

Guided wave radar level gauge and ultrasonic level gauge are two common liquid level measurement devices, and they have their own advantages in different application scenarios. This article will introduce the working principles, characteristics, applicable fields of these two liquid level gauges, and the factors that users need to consider when choosing.

1. Working principle

a. Guided wave radar level gauge: Use microwave signals to propagate and reflect in the waveguide, and calculate the liquid level by measuring the time delay of the reflected signal. .

b. Ultrasonic liquid level meter: emits ultrasonic pulses, measures the time it takes for the pulses to travel from the liquid surface to the bottom of the liquid and back again, and determine the liquid level by calculating the time difference.

2. Comparison of features

a. Guided wave radar level gauge: - High precision: suitable for complex liquid environments, such as grease and mud. -Not affected by temperature and pressure: stable performance under extreme conditions.

b. Ultrasonic liquid level meter: - Lower cost: Compared with guided wave radar, the price is more economical. -Suitable for most liquids: widely used for liquid level measurement of water, chemical liquids, etc.

3. Applicable fields

a. Guided wave radar level gauge: -Chemical plant: suitable for measuring the level of corrosive liquids. -Granary: It has good adaptability to granular materials.

b. Ultrasonic level gauge: - Sewage treatment: For general water treatment and water level monitoring. -Industrial water tank: for routine liquid level monitoring.

4. User considerations when choosing

a. Liquid properties: If corrosive liquids are involved, guided wave radar may be more suitable.

b. Cost budget: Ultrasonic liquid level meter has advantages in cost.

c. Application environment: Guided wave radar is more stable for conditions such as extreme temperatures and pressures.

d. Measuring range: Choose the appropriate measuring range according to actual needs.
