Measurement of water level is a lot of things done in various fields. There are many types of sensors that can be used to measure the water level. These sensors need to be tested and calibrated before use. One of the many sensor testing methods done is testing dynamically. In this research, a system that produces water surface oscillations will be used for sensor dynamically testing. The water surface oscillations are generated from the piston system which is connected to a transparent pipe. Surface level changes of water in the transparent pipe will be observed. This system can produce oscillation with frequency range between 0,05 - 0,45 Hz and height 26 - 37 cm. Frequency measurements are performed by the rotary encoder and processed by the microcontroller. Then testing of ultrasonic sensor and pressure sensor used this simulator.
