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.
