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: =Qf-Qg)/Qmax100%

    ģcited error
    Qfgranulated display value of flowmeter
    Qgactual flow value of flowmeter
    Qmaxtested 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:

        

  Qs:actual flow value
  QN:read display value of flowmeter
  Qf:density of floater
  N:Density of water at 20 under demarcated state
  S:density of liquid to be tested.
