Correct:
(1) When cone pipe and floater is dirt, clean it in time;
(2) Check the error of flowmeter regularly. Once over the regulated error, change the floater and cone pipe or demarcate it again.
(3) If the marking scale of liquid to be tested and flowmeter is same, the display value should be corrected in accordance with the liquid. The error of flowmeter is called as cited error. It can be expressed by the following formula: δ=（Qf-Qg)/Qmax×100%

δ：cited error

Qf：granulated display value of flowmeter

Qg：actual flow value of flowmeter

Qmax：tested upper limit value of flowmeter

correction of flow display value:

When the density of liquid to be tested is different from the density of water at 20 ℃ under demarcated state of scale, the display value of flow should be corrected by the following formula:

Q_s:actual flow value
Q_N:read display value of flowmeter
Q_f:density of floater
ρ_N:Density of water at 20 ℃ under demarcated state
ρ_S:density of liquid to be tested.
