4-20mA Integrated Two-Wire Liquid Level Gauge

Accuracy: Generally, the measurement accuracy can reach ±0.25% - ±1.0% of the measured value. Some high - end models can achieve an accuracy of up to ±0.2% of the measurement distance plus 0.05% of the full scale.​

Resolution: It can typically resolve small changes in the liquid level. For example, when the measurement distance is less than 2m, the resolution can be 1mm; for 2 - 5m, it is 2mm; for 5 - 10m, 5mm; and for distances greater than 10m, 10mm.​

Working Temperature: The instrument can usually work in a relatively wide temperature range. The probe can withstand temperatures from - 20℃ to 80℃, while the overall instrument can operate in an environment with a temperature range of - 20℃ to 60℃. However, different materials of the probe may have slightly different temperature resistance capabilities. For example, PP, PVDF, and PTFE - type probes can work in the range of - 30℃ to + 90℃, and stainless - steel - type probes can operate in the range of - 30℃ to + 100℃ (and can withstand CIP 120℃ cleaning for 2 hours).​

Power Supply: It is powered by DC24V, which is a common and stable power supply method in industrial applications.​

Product Advantages​

Non - contact Measurement: Since it uses ultrasonic waves to measure the liquid level, there is no need for the instrument to come into direct contact with the measured medium. This not only reduces the risk of corrosion and contamination of the instrument but also makes it suitable for measuring various liquids, including corrosive, viscous, or dirty liquids.​

High Accuracy: Equipped with advanced signal processing algorithms and high - quality ultrasonic transducers, it can accurately measure the liquid level. The intelligent echo analysis technology can effectively identify and process the echo signals, reducing the influence of interference and improving the measurement accuracy.​
