Active constant-temperature hydrostatic leveling system

The utility model discloses an active constant-temperature hydrostatic leveling system, which comprises a plurality of hydrostatic leveling gauges and a reference liquid storage barrel which are connected in series, and through the arrangement of a first loop and a second loop, liquid in the first loop is kept at constant temperature, the temperature of circulating liquid is controlled from inside or outside, and active temperature control is realized; the state of the system during measurement can be actively controlled to be consistent with the in-plant rate timing state, bubbles in the first loop can be discharged together in the liquid circulation process, and the bubbles leave the first loop after overflowing from the top of the liquid level of the reference liquid storage barrel, so that no bubbles exist in the hydrostatic level system, and the measurement accuracy is improved. The hydrostatic leveling system is always ensured to have higher measurement precision, namely, foam can be discharged while ac
