Vacorda instrument ultrasonic level gauge is a commonly used liquid level measurement tool, because it chooses a measurement method that does not need to be touched directly, the measured substance is almost unlimited, and it is often used in some work environments, which may be very complicated. Occasions with special requirements. It can be widely used to measure the height of various liquid and solid materials.
It has the following characteristics:1. The transmitting power is small, the energy is small, and it is flexible and convenient;2. The complete series of transducers can accurately complete non-touch continuous measurement in different environments;3. The accuracy of the small blind area is very high and the accuracy can still be maintained near the blind area;4. The integration of receiving and sending is more convenient and fast, and can accurately receive tiny echo signals to ensure the accuracy and reliability of measurement;5. It is safe, reliable, moisture-proof and anti-corrosion, suitable for different occasions, and is not affected by factors such as climate;Precautions for equipment requirements when using on-siteStraight device probeThe time and division of the transducer equipment, during the time and division of the transducer, ensure that the emitting surface is parallel to the liquid surface to be surveyed, so that the sound wave can be emitted perpendicularly to the surface of the object to be measured. In this way, the maximum energy can be returned.Equipment skills: Assuming that there is steam in the field environment, it is a simple form of water droplets attached to the surface of the probe. Because the range of the probe is relatively large, it is much larger than the distance to be measured in practice. Therefore, it should be tilted about 3 degrees so that the water droplets will not be affected.2. Avoid blind spotsThe distance from the high liquid level to the surface of the ultrasonic level gauge probe should be greater than the blind zone of the probe. Assuming that our equipment is a closed tank, the blind zone value should be increased by 20%. Assuming that because the liquid will agitate, a very long catheter is used for the equipment, then it is best to increase the blind area of the visual field by 20%. In order to avoid the blind area, we often use the method of lengthening the catheter to avoid the blind area. When using the extended catheter device, be sure to ensure the sharp angle of the probe.The wall of the tank is lubricated every day, and when it is refrigerated for a while, it will not be included in the words. It is one of the most equipment with a distance of 30 cm from the wall. The filling wall of the ultrasonic level gauge is rough, so the orientation of the probe device should be far away from the tank wall. The bottom of the tank is not flat, so there may be an error at the time of zero liquid level. Assuming it is a cone-shaped bottom surface, it can be considered that the probe device is directly above the top of the cone. Regarding the circular rod only one meter away, the Super Cup diameter is more than one centimeter of the moon, and the Super Cup does not make much noise. Otherwise try to avoid it. But for the horizontal bar and the tank wall at right angles, try to avoid it.Avoid mixing and not being firmIf there is mixing or not resolutely, you can use the extended pipe equipment, the pipe can be directly applied to the bottom surface of the liquid level, the diameter of the pipe only needs to be larger than the radiation surface of the probe, but it is best to ensure that the inner wall of the pipe is smooth and the liquid level rises and falls. No material hanging during the process, the liquid inside the tube and the outside of the tube are common. If a large range is not suitable for ultrasonic level gauge catheter equipment, the range can be reduced. The specific reduction depends on the size of the wave.
