Checks 

When  the  resistor  of  the  sensor  is  seriously 

damaged,  resulting  in  a  short  circuit  with 

the  pointer positioned  on  it 

Replace the sensor PCB. (If the float is 

out  of  the  position,  the  output  will 

sharply  rise  or  drop,  leading  to 

measurement error.) 

When  the  resistor  of  the  sensor  is  seriously 

damaged,  resulting  in  an  open  circuit  with 

the  pointer  positioned  on  it 

Replace the sensor PCB. (If the float is

When  the  wire  is  not  wound 

Check  if  any  foreign  subsidence  is  in 

the  wire  drum  or  if  the  spring  is 

damaged.

Hunting  of  the  Output 

Holding  of  the  Output  Current 

Understand  the  aforementioned,  and  never  use  it  to  measure  any  liquid  that 

exceeds 80°C. In addition, make sure that the ambient temperature of the housing 

is maintained at 

20°C ~ +60°C.
