The utility model discloses a static leveling instrument with double sensitive sensors. Tank body mounted on base, meanwhile, a bubble level is mounted on the base; the liquid level in the tank body is adjusted to a horizontal state through the bubble level; the measurement precision is prevented from being influenced by liquid level area change; a flow meter is further mounted on the base; the flow quantity of liquid is determined through the flow meter, meanwhile, the liquid level sensor is arranged at the top of the tank body and connected with the buoy in the tank body, when the liquid flows, rising or falling of a measuring point can be obtained by observing data of the liquid level sensor, and then the rising or falling height of the liquid level is calculated through parameters of the flow meter. According to the static leveling instrument with the double sensitive sensors, the tank body is horizontally placed, so that measurement errors are reduced, the change height of the liquid level can be accurately calculated through the flow meter, and the measurement precision is improved.
