Ineffective installation of radar level gauges may affect measurements

2021-08-05

Radar level gauges measure material height by emitting radar waves from an antenna, receiving the reflected waves, and calculating the distance. Various obstacles encountered during the emission and reflection of radar waves can reflect the waves, but this is not beneficial to the measurement. Radar level gauges employ technology to minimize interference as much as possible. Improper installation of a radar level gauge can affect measurement results; therefore, necessary reflections should be avoided during installation.

Difference between ultrasonic level meter and radar level meter

The ultrasonic level meter is a digital level instrument controlled by a microprocessor. During measurement, an ultrasonic pulse is emitted by a sensor (transducer), and the sound wave is reflected by the liquid surface and received by the same sensor or ultrasonic receiver. It is converted into an electrical signal by a piezoelectric crystal or magnetostrictive device, and the distance from the sensor to the surface of the measured liquid is calculated from the time between the emission and reception of the sound wave. Because of the non-contact measurement, the measured medium is almost unrestricted, and it can be widely used for measuring the height of various liquid and solid materials.

Precautions for using high-frequency radar level gauges

1. When measuring liquid materials with a high-frequency radar level gauge, the axis of the sensor and the surface of the medium must be kept vertical; when measuring solid materials, because the solid medium has an angle of repose, the sensor must be tilted at a certain angle.

The most common causes of error in radar level measurement

2021-08-05

In the liquid level measurement industry, radar level gauges have become the first choice for many users. This is because radar level gauges have a wider range of applications and advantages in installation and use compared to other measuring instruments. Of course, any product will have its own shortcomings. In fact, there are still many problems that need to be improved in radar level gauges, which are being gradually improved through our continuous technological advancements. So, let's take a look at the common errors that radar level gauges may encounter? This is how technical personnel who have long dealt with radar level gauges introduced it to me.

Four Common Failure Predictions for Guided Wave Radar Level Meters

1. Check if the power supply system is functioning properly. If it is found at the production site that the radar level gauge changes very slowly after the liquid level rises to the required value, the power supply system of the radar level gauge should be checked immediately. Relevant personnel should also carefully check the power consumption of the radar level gauge during daily maintenance, and whether there is normal output after power-on. If the liquid level changes slowly or does not change at all, check if the equipment fuse is blown. If there is no current output, it can basically be determined that there is a problem with the instrument, and it should be replaced or repaired as appropriate. In addition, the instrument should be

Ultrasonic sensor exposure issues

Ultrasonic sensors are simple, convenient, and inexpensive to use. However, current ultrasonic sensors have some drawbacks, such as reflection problems, noise, and cross-talk issues.

Differences in the names of radar level gauges

2021-08-05

Generally speaking, radar level gauge is a general term, which is the most common name in this industry. It has many names, such as level gauge, liquid level gauge, and material level gauge. It is also called radar liquid level gauge and radar material level gauge. The difference in the name of radar level gauge is that level gauge includes liquid level gauge and material level gauge, and radar level gauge includes radar liquid level gauge and radar material level gauge. Level gauge is just a short name for radar level gauge. They mean the same thing. The only difference from other names is the different substances being measured. Radar level gauge and level gauge refer to the measurement of both solids and liquids, while radar material level gauge and material level gauge generally measure solids.
