Ultrasonic Level Meters
Ultrasonic level sensor on working site
Ultrasonic level sensor is one type of sensor for level measuring.
It's used to measure water or waste water's level normally.
It have 24VDC two wire with 4-20mA output.
RS485 communication is optional.
Applications: the ultrasonic transmission can effectively spread to the measured liquid level or the occasion of a solid surface.
Such as: storage tank, chute, metering box, pools, tanks, well, ditch, moving objects and so on.
