Advanced Two-Wire Design for Industrial Automation with Ultrasonic Liquid Level Meter

The two-wire ultrasonic level meter is an instrument used to measure the level of liquid or solid materials. It is usually used in industrial automation, material monitoring and environmental management. Its working principle is to use the time difference of ultrasonic wave propagation in the medium to determine the liquid level. The device calculates the height of the liquid or the accumulation height of the material by emitting ultrasonic signals and receiving reflected signals.

Description

Ultrasonic liquid level gauge is a digital liquid level instrument 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 is received by the same sensor or ultrasonic receiver. It is converted into an electrical signal through a piezoelectric crystal or magnetostrictive device, and is transmitted and received by the sound wave. time to calculate the distance from the sensor to the surface of the liquid being measured. Due to the non-contact measurement, the measured medium is almost unlimited and can be widely used to measure the height of various liquid and solid materials.

Installation principle
When the ultrasonic liquid level meter is working, high-frequency pulse sound waves are emitted by the transducer (probe) and are reflected by the surface of the measured object (water surface). The refracted reflected echo is received by the same transducer (probe) and converted into an electrical signal. . The time between pulse transmission and reception (the movement time of the sound wave) is proportional to the distance from the transducer to the object surface. The relationship between the sound wave transmission distance S, the sound speed C and the transmission time T can be expressed by the formula: S= CⅩT /2
When installing an ultrasonic liquid level meter, the blind zone problem of the ultrasonic liquid level meter must be considered. When the liquid level enters the blind zone, the ultrasonic transmitter cannot measure the liquid level. Therefore, when determining the measuring range of the ultrasonic liquid level meter, a margin of 50 cm must be left. When installing, the transmitter probe must be higher than the maximum liquid level. The position is about 50 centimeters. Only in this way can the accurate monitoring of the liquid level and the safety of the ultrasonic liquid level meter be ensured.
In actual use, due to poor installation considerations, the liquid level gauge was submerged in water, causing the liquid level gauge to be completely damaged.
Features of SGM ultrasonic level meter
Low price, small size and light weight, it can be used for non-contact level measurement of liquids and bulk solids in food, chemical, semiconductor and other industries, and can be used for remote level monitoring and pump control.
Attention should be paid to mechanical installation: the installation should be perpendicular to the surface of the object to be measured, avoid being used to measure foam objects, and avoid being installed at a distance less than the blind zone distance from the surface of the measured object (blind zone: each product will have a standard, which will be known with the product) , it should be considered that the beam avoids blocking materials and does not meet the filling mouth and container wall. When detecting large solid objects, the probe orientation should be adjusted to reduce measurement errors.
