The basic error of the flowmeter is calculated by the following values ​​from the respective measured flow points: (volume method) E=(Vm-V)/V*100%
The basic error of the flowmeter is calculated by the following values ​​from the respective measured flow points: (volume method)
E=(Vm-V)/V*100%
E: Flowmeter error (generally referred to as cumulative error) takes two significant digits
Vm: measured value of the flowmeter (ie display value)
V: After correction, the flow standard device measured value (actual value)
Known by the basic error calculation formula, when
When Vm>V, the basic error of the flowmeter is “+†value, indicating that the flowmeter is going faster.
When Vm < V, the basic error of the flowmeter is "-" value, indicating that the flowmeter is slow.
