The accuracy and stability of liquid level measurement directly affect production efficiency, safety management, and cost control in fields such as industrial production, environmental monitoring, and water conservancy engineering. Traditional liquid level measurement equipment often faces problems such as poor anti-corrosion performance, susceptibility to interference, and complex installation and maintenance, making it difficult to meet the requirements of complex working conditions. The LFUD101 integrated ultrasonic level gauge, with its advantages of safety, cleanliness, high precision, and long service life, has become an ideal choice for solving various level measurement problems. It is widely used in corrosive environments such as acid, alkali, salt, and high temperature conditions.
From the perspective of core performance, the measurement capability of LFUD101 integrated ultrasonic level gauge covers multiple scene requirements. Its measurement range can be flexibly selected within 0-30m according to actual needs, and it can accurately adapt to both small storage tanks and large water tanks. The blind spot is controlled at+0.5% of the full range (under standard conditions), and the ranging resolution reaches 1mm. Even in the face of small fluctuations in liquid level, accurate data can be captured in real time to avoid production misjudgment caused by measurement errors. In terms of pressure adaptation, the equipment supports normal pressure conditions without the need for additional pressurization or depressurization devices, reducing the threshold for use in complex working conditions.
The humanized design of the display function makes the acquisition of liquid level data more intuitive and efficient. The device comes with an LCD display screen, which can not only clearly display the "liquid level value" (distance from the bottom of the pool or tank to the medium surface) and "distance value" (distance from the probe surface to the medium surface), but also innovatively add the function of echo curve display. The staff can determine in real-time whether the measurement signal is stable and whether there is interference through the echo curve, and can complete preliminary troubleshooting without disassembling the equipment, greatly improving operation and maintenance efficiency.
The flexible configuration of output and power supply systems further expands the application scenarios of equipment. The output methods are divided into two-wire and four wire systems: the two-wire system has an output of 4~20mA/250 Ω, and can also be equipped with the HART protocol, which is suitable for scenarios that are sensitive to wiring costs and require remote communication; In addition to 4-20mA/510 Ω output, the four wire system also integrates RS485 interface (compatible with standard Modbus RTU protocol, supporting system parameter modification), and is equipped with relay output (250AC/5A or 30VDC/2A), which can directly link control equipment such as pumps and valves to achieve automatic liquid level regulation. In terms of power supply, the two-wire system comes standard with DC24V. In addition to DC24V, the four wire system can also be optionally equipped with DC12V or AC (100-240) V wide voltage to adapt to different on-site power supply conditions without the need for additional transformers.
In terms of environmental adaptability and safety, the LFUD101 integrated ultrasonic level gauge performs equally well. The equipment has a protection level of IP65, which can effectively resist dust intrusion and low-pressure water spray, and can operate stably even in humid and dusty industrial environments. The environmental temperature adaptation range is -20 ° C~+60 ° C. Whether it is cold outdoor storage tanks in the north or high-temperature chemical reaction vessels, they can work normally without the need for additional insulation or cooling devices. More importantly, all input and output lines of the instrument have lightning protection and short-circuit protection functions, which can effectively protect the core components of the equipment and reduce maintenance costs and downtime risks in areas with frequent thunderstorms or line failures.
Energy consumption control is also a major highlight of this device. When there is no relay output, the power consumption of a four wire instrument is only< 24V@80mA Two line instruments have lower power consumption and only require< 24V@30mA It is much lower than traditional liquid level measurement equipment. Long term use can not only reduce electricity consumption, but also lower equipment heat dissipation pressure and extend service life.
In terms of model selection, the LFUD101 series offers diverse configurations to meet the needs of different users. For example, the "LFUD101-0~3m-A4MD-0.5%" model represents a measurement range of 0-3m, an output mode of 4-20mA+RS485+two-way relays, and an accuracy of 0.5% (conventional ABS probe). Users can accurately choose the appropriate model based on actual range, output requirements, and probe material preferences to avoid functional redundancy or insufficient performance.
Nowadays, the demand for intelligent and efficient liquid level measurement in the industrial field is constantly increasing. The LFUD101 integrated ultrasonic liquid level gauge has become the preferred equipment for industries such as chemical, environmental protection, water conservancy, and food processing due to its precise measurement performance, flexible configuration scheme, and strong environmental adaptability. Whether it is monitoring the liquid level of corrosive medium storage tanks or regulating the liquid level of municipal sewage treatment plants, LFUD101 can play a stable role, helping enterprises improve production efficiency, reduce operation and maintenance costs, and ensure production safety.
