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.
