VLS730 Ultrasonic Level Meter 4-20mA Water Tank Level Sensor
Our Votesen VLS731 Standard Type (Normal Temperature) Integrative Ultrasonic Level Meter is a universal level measuring instrument for liquid, solid, and gel. It takes the different advantages of various level measuring instruments. It has perfect level monitoring, data transmission, and man-machine communication. It is fully digital with an on-site display.
It is featured by strong anti-interference performance; free setting of upper and lower limits and online output regulation, on-site indication, optional analog, switching value, and RS485 output, and easy connection with the main unit.
It is manufactured with an engineering plastic ABS waterproof case and a high-quality multi-layer PCB board, designed with a modular circuit. The main chip adopts dozens of related ASICs with import industrial-grade single-chip microcomputer to make it with perfect features of digital temperature compensation and ultra-wide voltage input voltage regulation.
This product can meet most liquid level and material level measurement requirements without contacting industrial media. It can completely solve the shortcomings of traditional measurement methods (Pressure Type, Capacitive Type, Float Type), such as winding, blockage, leakage, medium corrosion, inconvenient maintenance, and other problems.
Therefore, it is applicable to various fields concerning level measuring and monitoring.
