1, Principle of Ultrasonic Distance Measurement
The ultrasonic transducer emits high-frequency ultrasonic pulses onto the surface of the measured medium. The sound waves propagate at a fixed speed in the medium and reflect back to the transducer upon encountering the surface of the medium (such as liquid or solid materials). After receiving the reflected wave, the transducer accurately calculates the time interval Δ t from the transmitted pulse to the received pulse through the built-in circuit. According to the formula, distance L=sound velocity C × Δ t/2 (due to the back and forth propagation of sound waves, it needs to be divided by 2), the actual distance from the transducer to the surface of the medium can be obtained. At the same time, the equipment optimizes echo signal processing through Outec's exclusive long wave, medium wave, and short wave algorithms, and utilizes manual/automatic sound speed correction functions to compensate for sound speed changes in real-time based on environmental temperature and humidity, ensuring measurement accuracy of 0.2% FS.
2, Core parameters and performance
-Ultra large measurement range: With a 30 meter ultra large measurement range, it meets the liquid level monitoring needs of various large storage tanks, water tanks, and other scenarios.
-High precision measurement: using 0.2% FS high-precision measurement technology, combined with Outec's exclusive long wave, medium wave, and short wave algorithms, intelligently optimizing echo signal processing; Built in manual/automatic sound speed correction function, compensates for sound speed errors in real-time based on environmental temperature and humidity, ensuring reliable data.
3, Flexible adaptation capability
(1) Transducer selection
We provide various frequency ultrasonic transducers such as 100kHz, 64kHz, 40kHz, 26kHz, 21kHz, etc. The high frequency is suitable for short distance high-precision measurement, and the low frequency is suitable for long-distance and strong interference environment detection. At the same time, the transducer materials include ABS, POM, PTFE: ABS is economical and durable, suitable for conventional environments; POM has excellent corrosion resistance and wear resistance; PTFE (polytetrafluoroethylene) has chemical stability and can withstand strong corrosive media such as strong acids and alkalis, making it suitable for different working conditions.
(2) Power supply plan
Supports three power supply modes: 12V DC, 24V DC DC power supply, and 220V AC power supply, adapting to various industrial environment power needs and enhancing deployment flexibility.
4, Rich functional design
(1) Measurement mode
Supports two working modes of dual independent level measurement and liquid level difference comparison, which can synchronously monitor data from two points and accurately calculate the liquid level difference. It is widely used in fields such as water supply and drainage, water conservancy engineering, and industrial tank monitoring.
(2) Alarm and output
-Alarm function: Equipped with 2-4 relay alarm outputs, users can freely and independently set alarm thresholds to achieve over limit warning and equipment linkage control.
-Analog output: 2-channel 4-20mA standard current transmission output, which can correspond to the level values of each circuit or flexibly switch to liquid level difference data output, seamlessly integrated with PLC, DCS and other control systems.
-Digital Communication: Integrated RS485 communication interface (Modbus protocol), optional 4G full network wireless communication module or LoRa wireless RF transmission module, to meet the needs of remote data acquisition and real-time monitoring.
5, Intelligent interactive experience
Equipped with a backlit dot matrix LCD display screen, it supports three major display interfaces: level, distance, and waveform. It can simultaneously display measurement values, distance data, and multiple echo curves. Through intuitive waveform display, it assists users in quickly locating interference sources and blind spots. With one click switching operation, it significantly improves on-site debugging efficiency.
6, Reliable and durable design
The instrument split type housing is made of industrial grade aluminum material, which has anti-corrosion and electromagnetic interference resistance, and can adapt to harsh industrial environments such as high temperature, humidity, and dust, ensuring long-term stable operation of the equipment.
application area
Can be used in: petrochemical industry, environmental water treatment, water conservancy and hydropower engineering, food and pharmaceutical industry, warehousing and logistics field, energy industry
