Revise
Flow accuracy curve correctFactor,11 points
Speed_1 ~ Speed_11 presents the flow velocity, you can set 11 point single flow velocity
Revise_1 ~ Revise_11 separately to corresponding Speed_1 ~ Speed_11, it use on amend the
inaccuracy by the flow velocity amend.
Use
button to move, button to change the value, Any related setting sample please see
below.
ps: normally flowmeter accuracy it’s during standard accuracy, only if it’s necessary, please do
not adjust any accuracy curve or you can ask Alia professional engineer to adjust with you
Example 1 : size :50 mm(2”), Calibration flowrate are:0.5 M3/Hr, 1 M3/hr, 2 M3/Hr, 4
M3/hr,
totally 4 points, first calibration result as follow:
4point flowrate, its inaccuracy calculation as follow:
Point 1: 0.5/ 0.530 = 0.943 , new Revise valve = 0.943
Point 2: 1 / 0.983 = 1.017, new Revise valve= 1.017
Point 3: 2 / 2.046 = 0.978, new Revise valve= 0.978
Point 4: 4 / 4.176 = 0.958, new Revise valve= 0.958
Filled the 4 points Revise valve in order to the new flow Velocity adjust parameter as
follow:
You will get the digit :
Speed_1= 0.071, Revise_1=0.943, Speed_2=0.142, Revise _2=1.017
Speed_3= 0.283, Revise_3=0.978, Speed_2=0.566, Revise _4 =0.958
Separately filled the converter related parameter,then the adjustment finished, that
times Revise_5, Revise _6, Revise _7 , Revise _8 , Revise_9, Revise _10,
Revise _11, Speed_5, speed_6 , Speed_7, speed_8 , Speed_9, speed_10
speed_11 doesn’t need to change
