Explain the GKL value of a magnetic flow meter
It is a numerical value against head resistance
GK and GKL is coil constant resistance value of magnetic flow head, both values depend on Factor, if Factor is 1 then we use GK value and if Factor is 2 then we use GKL value, these values are mentioned at flow head nameplate
which factor can you explain please and why do we change GK GKL values of flow head
The GKL value of magnetic flow meter is the numerical index, which reflects a coil constant resistance of the magnetic flow head. It is connected most cohesively with the head resistance and defines the accuracy and productivity of the flow meter. Being similar, both GK and GKL values are labeled on the flow head nameplate with Factor as another varying parameter.
The Factor addresses the setup condition of the flow meter and it determines whether the coil constant value to be used is the GK or the GKL. In the case when the Factor is equal to 1 the program applies the GK value. However, when the Factor is 2, the value of GKL is applied. These values are crucial in order to provide the necessary optimum conditions for its proper functioning of the flow meter.
The rationale for switching between GK and GKL depends on the particular head resistance of the application flow meter. When the resistance increases or any of other system conditions change, the correct coil constant, either GK or GKL, assists in getting an accurate flow rate measurement. This alteration helps equalise the flow and keeps the output of the meter accurate irrespective of the conditions in the flow.
Therefore, to get to when using GK or GKL is crucial in order to have the flow meter running as planned and provide good results in various operational settings.
