Ultrasonic level gaugeEasy installation, maintenance, and calibration. The product is widely used for level measurement in industries such as chemical, water treatment, water conservancy, food, and grain. It has the characteristics of safety, cleanliness, high accuracy, long service life, stability and reliability, easy installation and maintenance, and simple reading.Ultrasonic level gaugeDuring operation, high-frequency pulse sound waves are emitted by a transducer (probe) and reflected off the surface of the object being measured (water surface). The reflected echoes are received by the same transducer (probe) and converted into electrical signals. The time between pulse transmission and reception (the motion time of sound waves) is proportional to the distance from the transducer to the surface of the object. The relationship between the distance S of sound wave transmission, the speed of sound C, and the transmission time T can be expressed by the formula: S=C X T/2

When the liquid level enters the blind zone,Ultrasonic transmitterIt is impossible to measure the liquid level, so it is necessary to determine the excessAcoustic level gaugeWhen measuring the range, a margin of 50 centimeters must be left, and during installation, the transmitter probe must be about 50 centimeters above the liquid level. This is the only way to ensure accurate monitoring of the liquid level and ensure the safety of the ultrasonic level gauge.

During mechanical installation, attention should be paid to: the installation should be perpendicular to the surface of the object to be measured to avoid measuring objects with foam properties, and the installation should not be less than the blind zone distance from the surface of the object to be measured (blind zone: each product will have a standard, which will be known with the product). The beam should avoid blocking objects and not meet the tank mouth and container wall. When detecting large solids, the probe orientation should be adjusted to reduce measurement errors

Ultrasonic level gaugeNormal use requires controlling stress factors. When installing the ultrasonic level gauge, do not let its high material enter the blind spot. When using a level gauge, maintain a certain distance and install it perpendicular to the liquid level. Ultrasonic level gauges are affected by temperature during measurement, and the speed of sound does not change significantly at normal temperatures, with a short propagation time. However, if there are significant temperature fluctuations, measurement errors may occur. Some of the more advanced measuring instruments have excellent temperature sensing and software functions, which can compensate for temperature. The influence of pressure on ultrasonic level gauges mainly affects their probes, and does not affect their sound velocity changes.
