Guided wave radar level gauges are often used in industrial production, and are accepted by the public because of their superior performance. It has the advantages of low maintenance cost, strong detection performance, accurate measurement accuracy, high safety, and long service life. The signal emitted by the device is not affected by the environment, atmosphere, etc., so it can be used in a variety of special media, such as high temperature, high pressure, steam state, volatile gas, dust, vacuum environment, etc.

Based on the usage data fed back by the guided wave radar level gauge under various conditions, it can be continuously powered with high accuracy, and does not require frequent manual maintenance compared to other level gauges. Today we want to share with you how to use the guided wave radar level gauge in the boiler. The high temperature and high pressure in the boiler need to use the liquid level gauge to measure the internal liquid level to ensure its safety. The use of guided wave radar level gauges can solve several difficult problems of safety, accurate readings, and simple maintenance.

On some boilers, at least two independent water level gauges need to be installed for each boiler installation, so each boiler also needs to be equipped with two guided wave radar level gauges. Only in this way can the safety requirements of boiler operation be fully met. The guided wave radar level meter needs to use a quartz tube to observe the liquid level change in the furnace, but the connecting pipes and valves need to be opened to improve the detection accuracy. When installing, it is necessary to ensure that the probe and sensor are dry and clean. If contamination occurs, it cannot be wiped with a wet towel, but decontaminated with alcohol.

Although many cities do not have standard regulations for boiler level gauges, at least one intuitive level gauge needs to be installed, together with a guided wave radar level gauge for observation. If it is a large and complex boiler complete set of equipment, it is necessary to redesign and plan the guided wave radar level gauge, and install it according to the design drawing.

Under normal circumstances, the guided wave radar level gauge used in boilers has the following faults:

1. The influence of thick foam on the measurement, the foam medium will absorb, reflect and diffuse the radar signal of the liquid level gauge, which will affect the detection result. In this case, the guided wave radar level gauge has no advantages, and other level gauges need to be replaced.

2. The probe and sensor are faulty. In this case, the height of the device needs to be readjusted, and the position is determined after detecting several sets of data.

3. The antenna is polluted or damaged by external force. Contaminated antennas can be cleaned with alcohol. If the external force is damaged, you need to replace the accessories and use it after re-commissioning.
