Observer for water level of pressure tester

The utility model provides a universal observer for water level of a pressure measuring pipe of a reservoir dam, which is formed by installing a power supply, a motor, a drive mechanism, a counter, a sensor, a displayer, a memory, etc. in the same machine case. When the utility model works, a probe is driven to descend by the motor through the drive mechanism; after the probe contacts the water surface in the pressure measuring pipe and is stabilized, the probe ascends and the counter counts; when the probe comes back to a limiting position, the water level measurement is completed; results are automatically stored and displayed. The utility model has the advantages of automatic measurement, high precision and strong adaptability. The utility model can directly carry out remote measurement by connecting with a computer. The utility model is suitable for the observation of the water level of a pressure measuring pipe of a reservoir dam, and is suitable for the observation of the water level of reservoirs, rivers, lakes, water towers, ponds or other containers.
