The ultrasonic level meter is one of the most popular measuring instruments out there. Just about every industry and person that needs to measure the level and distance of an object can use the ultrasonic level meter for accurate measurements. There are certain factors which one needs to consider when they think about purchasing ultrasonic level meter.
Soft Vs Hard Targets
The job of the ultrasonic level meter is to measure the level of the target. The target can either be soft or hard and that is why it is important to know how the ultrasonic level meter measures these two. You need to consider the type of target which you need to measure.
The ultrasonic level meter works best with hard targets or targets which have good reflective characteristics. The best targets are those which are smooth like most liquids or flat. Whereas, soft targets have poor reflective characteristics such as grains and sand. It can be difficult to measure soft targets. When the ultrasonic level meter targets a soft target, the ultrasonic waves will mostly just get scattered or deflected. Therefore, it is important for you to consider your target before purchasing ultrasonic level meter, so as to make the most of it.
Another important factor which you have to consider when you plan on purchasing ultrasonic level meter is the sensing distance. It means that you should know the maximum distance which the ultrasonic sensor would be able to detect. As a rule of thumb, one should use a sensor that would cover a maximum distance of plus 25 percent. It will help ensure that the pulses that it generates are strong enough to be able to reach the target and return to the sensor. Therefore, always consider the sensing distance of ultrasonic level meter before making a purchase.
The area within the first few feet or inches of the transducer where the targets are unable to be measured is known as the blanking distance. Normally, the longer the range of the ultrasonic sensor, the longer its blanking distances. Therefore, it is vital for you to know about the blanking distance before you consider purchasing the ultrasonic level meter. There might be cases where someone might even require a longer range ultrasonic sensor and a short blanking distance. Hence, always know about all your requirements beforehand.
