Guided wave radar level gauge

Guided wave radar level gaugeOverview:

Guided wave radar level gaugeIt is a microwave level gauge, which is an application of microwave (radar) positioning technology. It emits energy waves (usually pulse signals) through a device that can emit energy waves. The energy waves are transmitted in a waveguide and reflected when encountering obstacles. The reflected energy waves are transmitted from the waveguide to the receiving device, which then receives the reflected signal. Determine the level change based on the time difference of the measured energy wave motion process. The microwave signal is processed by electronic devices and ultimately converted into an electrical signal related to the material level. The energy radiation level is low, and the device uses pulsed energy waves (with a frequency generally lower than that of smart radar level gauges). The maximum pulse energy of a typical pulse energy wave is around 1mW (with an average power of around 1 μ W), which will not cause radiation damage to other equipment or personnel.

Guided wave radar level gaugeCharacteristics of

1. Strong universality: capable of measuring liquid and material levels, meeting measurement requirements for different temperatures, pressures, and media. The highest measurement temperature can reach 800 ℃, and the highest pressure can reach 5MPa. It can also be applied to harsh environments such as corrosion and impact.

2. Anti hanging material: The circuit design and sensor structure of * ensure that its measurement is not affected by sensor hanging material, and there is no need for regular cleaning to avoid measurement errors.

3. Maintenance free: There are no movable parts during the measurement process, and there is no mechanical component damage issue, so no maintenance is required.

4. Anti interference: contact measurement, strong anti-interference ability, can overcome the influence of steam, foam and agitation on measurement.

5. Accurate and reliable: Diversified measurement quantities make measurements more accurate, measurement is not affected by environmental changes, high stability, and long service life.
