S10, according to the corresponding relationship of air pressure in liquid level in the preset liquid reserve tank 10 and detection bucket 20, when the liquid storage
When default liquid level is H0 in case 10, the preset pressure value P0 in the corresponding detection bucket 20 is obtained；
S20 obtains the current gas in the detection bucket 20 when the water inlet 21 of the detection bucket 20 is communicated with the atmosphere
Pressure；
S30 increases the amount of liquid in the liquid reserve tank 10, obtains the air pressure in the detection bucket 20；
S40, when the absolute value of atmospheric pressure value and the preset pressure value P0 difference in the detection bucket 20 is less than or equal to
When the first preset value, stop increasing the amount of liquid in the liquid reserve tank 10, and save current level, to refer to liquid as described
Position.
When atmospheric pressure value variation is Δ P in the detection bucket 20, liquid level variation is Δ H in the corresponding detection bucket 20Bucket, right

Atmospheric pressure, at this time PAtmosphere×s×HBucket=nRT when water level increases to H1 in liquid reserve tank 10, detects liquid level correspondence in bucket 20 and rises to
L1, detecting closed gas air pressure in bucket 20 is P1, at this time P1×s×(HBucket- L1)=nRT=PAtmosphere×s×HBucket, P1=PAtmosphere+ρg
(H1-l1), according to above formula H1/L1=P1/ (ρ g)/HBucket+ 1, ρ=1000kg/m3, g=9.8N/kg, HBucketWhen no more than 102mm,
H1/L1 >=0.001 × P1+1 can obtain when P1 value is greater than or equal to 99960 ρ a (1 standard atmospheric pressure is 101325 ρ a)
H1/L1 is greater than 100 out, therefore, can ignore L1 changing value in this case.It should be noted that when close in detection bucket 20
When closing gas atmosphere value less than 99960, by adjusting HBucketThe ratio of height also adjustable H1/L1, to ignore L1 variation
Value.
