Ultrasonic level gauge
The ultrasonic level gauge is a digital level gauge controlled by a microprocessor. In the measurement, the ultrasonic pulse is emitted by the sensor (transducer). The sound wave is reflected by the liquid surface and then received by the same sensor. It is converted into an electrical signal by a piezoelectric crystal. The time between the transmission and reception of the sound wave is used to calculate the sensor to the Measure the distance to the surface of the liquid. Due to the non-contact measurement, the measured medium is almost unlimited, and it can be widely used for height measurement of various liquid and solid materials.

Product Introduction
Ultrasonic level gauge is a monitoring instrument for measuring liquid height, tank height, and material location. The instrument itself can adopt two-wire, three-wire or four-wire technology. The two-wire system is: power supply and signal output are shared; the three-wire system is: power supply circuit and signal output circuit are independent. When DC 24v power supply is used, a 3-core can be used Cable, the power supply negative terminal and the signal output negative terminal share a core wire; the four-wire system is: when AC 220v power supply is used, or when DC 24v power supply is used, and the power supply circuit and the signal output circuit are required to be completely isolated, one core should be used. A 4-core cable. DC or AC power supply, with 4~20mADC, high and low switch output.
Anticorrosive ultrasonic level gauge
Anticorrosive ultrasonic level gauge
Range: 0-60 meters, various forms are available, suitable for various corrosive and chemical occasions, high precision, remote signal output, PLC system monitoring.
The ultrasonic level gauge is composed of three parts: ultrasonic transducer (probe), drive circuit (module), and electronic liquid crystal display module.

Working principle
The working principle of the ultrasonic level gauge is that the ultrasonic transducer (probe) sends out a high-frequency pulse sound wave when it encounters the surface of the measured level (material) and is reflected and folded back. The reflected echo is received by the transducer and converted into an electrical signal. The propagation time of the sound wave. It is proportional to the distance from the sound wave to the surface of the object. The relationship between the sound wave transmission distance S and the sound speed C and the sound transmission time T can be expressed by the formula: S=C×T/2.
Because the transmitted ultrasonic pulse has a certain width, the reflected wave and the transmitted wave in a small area close to the transducer overlap, which cannot be identified and the distance value cannot be measured. This area is called the measurement dead zone. The size of the blind zone is related to the model of the ultrasonic level meter.
The probe part emits ultrasonic waves. When the ultrasonic waves encounter a medium with a large difference in density from the air, they will reflect, and the reflected waves will be received by the probe part. The distance from the probe to the liquid (object) surface is proportional to the time the ultrasonic waves pass:
Distance [m] = time × speed of sound/2 [m]
The temperature compensation formula of the speed of sound: ambient sound speed = 331.5 + 0.6 × temperature

Site conditions
In any of the following situations, pay attention:
Liquid/solid with foam
There are strong voltage, strong current, strong electromagnetic interference around, try to avoid high voltage, high current and strong electromagnetic interference
Strong wind and direct sun
Strong vibration
Sites with highly volatile liquids and large amounts of water vapor
Easily crystallized liquid
When encountering the above-mentioned field environment, you must choose to use it carefully, the accuracy of the measured value will be reduced, and the data may be unstable. Generally, it is not recommended to use an ultrasonic level gauge to measure.

Application area
Water and sewage treatment: pump room, collection well, biochemical reaction tank, sedimentation tank, etc.
Electric power, mines: mortar pool, coal slurry pool, water treatment, etc.
