Product Details
In fields such as environmental monitoring, industrial production, and municipal operation and maintenance, the accuracy, stability, and convenience of liquid level measurement directly determine production efficiency, safety control, and environmental compliance quality. Liaoning Xinruipeng Environmental Protection Technology Co., Ltd. is deeply engaged in the field of environmental protection instruments, relying on mature technology and localized service advantages to launchIntegrated two-line ultrasonic level gaugeBy integrating core features such as non-contact measurement, energy-saving wiring, and environmental adaptation, it has become the preferred product for government and enterprise procurement in Northeast and North China regions with high cost-effectiveness and reliability. It is widely used in various liquid level monitoring scenarios to meet the diverse needs of grassroots operation and industrial control.
1、 Core Measurement Principles
Liaoning Xinruipeng Environmental ProtectionIntegrated two-line ultrasonic level gaugeThe time difference distance measurement method used relies on the emission and reflection of ultrasonic pulses to achieve non-contact liquid level measurement, without the need for direct contact with the measured medium. This fundamentally avoids the loss of equipment caused by medium corrosion and blockage, greatly improving the service life and measurement stability of the equipment. Its working principle can be divided into five key steps: firstly, high-frequency pulse sound waves are emitted by the built-in ultrasonic transducer (probe) of the equipment, and the sound waves penetrate the air medium and propagate to the surface of the measured liquid; Secondly, sound waves reflect off the liquid surface, forming echoes that are received by the same transducer; Subsequently, the transducer converts the reflected sound wave signal into an electrical signal and transmits it to the built-in microprocessor; The microprocessor accurately calculates the time difference between the emission and reception of sound waves, and compensates for the sound velocity based on the ambient temperature (ambient sound velocity=331.5+0.6 × temperature) to eliminate the impact of temperature changes on measurement accuracy; Finally, according to the core formula of "distance=sound velocity x time difference ÷ 2", the distance between the probe and the liquid level is calculated. Combined with the preset container parameters, it is converted into the actual liquid level height and output through a 4-20mA current signal to achieve real-time monitoring and data transmission.
Compared to traditional liquid level measurement equipment, this product adopts an integrated design, integrating the probe, driver circuit, signal processing module, and display module into one, without the need for additional disassembly and installation; At the same time, adopting a two-wire technology enables the sharing of two lines for power supply and signal output, greatly simplifying the wiring process, reducing installation costs and later maintenance difficulties, especially suitable for monitoring scenarios with limited space and inconvenient wiring. In addition, the device is equipped with an enhanced transmission module and adaptive filtering technology, which can effectively suppress interference echoes, accurately identify effective signals, and ensure the authenticity and stability of measurement data even under complex working conditions.
