Pulse radar level meter

A list,

Pulse radar level meter is suitable for various process conditions of complex containers, tanks, silos and so on, and is not affected by the physical characteristics of the measured medium change, external measurement, two-wire system technology, suitable for explosion-proof occasions, non-contact and continuous measurement of pulse level care about the large measurement distance of 35m. Pulse radar level meter is suitable for non-contact continuous measurement of the level of liquid, slurry and granular materials, and temperature, pressure changes, there are inert gas and volatile occasions. The level meter of pulse radar is measured by microwave pulse and can work normally in the range of industrial frequency band. Beam energy is low, can be installed in a variety of metal, non-metal containers or pipelines, no harm to human body and the environment.

Characteristics and advantages of level meter of pulse radar

1. No blind spot, high precision.

2. Two-wire system technology is an excellent substitute for differential pressure instrument, magnetostrictive instrument, RF admittance and magnetic turning plate instrument.

3. It is not affected by pressure change, temperature change, inert gas, vacuum, smoke, steam and other environment.

4. Easy installation, firm and durable, maintenance-free.

5, HART or PROFIBUS-PA communication protocol and fund fieldbus protocol, calibration is simple, easy to achieve field calibration operation through digital liquid crystal display, through the software GDPF to achieve simple configuration setting and programming.

6. Sensitive measurement and fast refresh speed.

7, suitable for high temperature conditions, up to 200℃ process temperature, when the use of high temperature extension antenna can reach 300℃.

3. Measuring principle of pulse radar level meter

The radar object antenna emits a narrow microwave pulse which is transmitted down through the antenna. Microwaves touch the surface of the measured medium and are reflected back to be received by the antenna system, which transmits the signal to an electronic circuit and automatically converts it into a target signal (because of the speed of microwave transmission, the time it takes for the electromagnetic wave to reach the target and be reflected back to the receiver is almost instantaneous).

Principle of Radar Level Meter

The datum of measurement is: the bottom of the thread or the sealing surface of the flange.

Note: use the radar level timing, be sure to ensure that very high material level can not enter the measurement blind area.
