Weighing steam infiltration meter

The invention relates to a weighing steam infiltration meter, which is used for monitoring and testing the transpiration and leakage of water in soil. The weighing steams infiltration meter disclosed by the invention comprises an internal barrel made of metal material and an outer barrel arranged outside the internal barrel. A thermal insulation material is arranged in the outer barrel, and the soil of which the quality is the same as that of the soil to be monitored is filled in the internal barrel. A water-proof edge is arranged between the upper surface of the soil and the upper edge of the internal barrel. A water sensor, a temperature sensor and a thermal flux sensor are respectively arranged in the soil put in the internal barrel. The test signal output wires of the sensors are connected with a signal collection controller which is arranged outside the outer barrel. Three compressive springs which are used for supporting the internal barrel and the fixed weights of the soil in the internal barrel, and a
