Product Details
KUS630 Series Ultrasonic Level Meter
1.Features
- It is a non-contact measuring instrument that uses the working
principle of ultrasonic distance measurement and uses the time
difference between ultrasonic emission, object reflection and echo
reception to measure the measured distance.
- The use of advanced ultrasonic detection methods does not cause
false alarms due to external environmental changes or interference
like infrared and microwave detection methods.
- The alarm distance can be set flexibly. When the vehicle is in
place and the measured distance is less than the preset distance,
an LED light signal will be generated, and the vehicle arrival
information will be sent to the controller through the RS-485
interface.
- When measuring the material level distance, it does not touch the
measured object and has no moving parts. It is easy to install and
debug, easy to repair and maintain, and has high measurement
accuracy. The power consumption of the detector is extremely low,
and the RS485 output interface is adopted. The interface is simple,
safe, reliable, and stable, and is suitable for secondary
development.
- It can reliably detect whether the vehicle is in the parking space,
and has anti-false detection functions, such as preventing false
detection of adjacent parking spaces, false detection of people in
parking spaces, false detection of obstacles, etc.
- Completely independent development, with all intellectual property
rights and production technology, to provide good technical service
guarantee, high quality and low price.
