Different monitoring objects are monitored by different departments, so that the types of the installed monitoring sensors are different. Different types of sensors all need energy equipment, transmission equipment and the like, and because the installation departments of the equipment are different and have time difference, the equipment is repeatedly installed, and the cost is increased; 2. some sensors are easily damaged. The water level monitoring device of a common rainwater pipe well (vertical shaft) is a contact type water level sensor (such as a pressure type liquid level meter and the like), and the device converts pressure sensed by a small hole on a probe into water level height.
