High precise 4-2mA ultrasonic level meter 5-8m ultrasonic sensor
Product Description
KUMA-A ultrasonic level meter realizes high digital, communication
between machine and human. The CPU applies import industry
monolithic integrated circuit, digital temperature compensation and
wide voltage input. You can select analog, switch or RS485 serial
signal output. Owning the advantage that there is no need to
contact the measured meter, it could supply more precise and longer
work life.

Ultrasonic Level meter Instruction Manual
1,General information
KUMA-A ultrasonic level meter, taking the advantages of various
many level measuring instruments, is a universal one characterized
by total digitalized and humanized design. It has perfect level
monitoring, data transmission and man-machine communication. The
CPU applies import industry monolithic integrated circuit, digital
temperature compensation. 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
main unit. The cover, made of waterproof engineering plastics
(ABS), is small and firm with PP probe or stainless steel probe.
Its main circuit board applies quality SMT components and keyboard,
making it more stable and reliable. Therefore, it is applicable for
various fields concerning level measuring and monitoring.

4,Menu operation and parameters setting
Note: The sequence of digit input is “0～9 .–”, and the current
parameter is saved when “A” is pressed to enter next menu. During
setting press”A” for a long time at any time to exit current menu.
After setting, “A” must be pressed for a long time to exit. In case
of wrong input and no need to save, just turn off the power.
