1. Flowmeter Check
A. Check the overwrap first, if any damages occur, contact ALIA Customer Service Center at once.
B. Confirm whether the instrument has been damaged or its spares are lost.
C. It’s recommended that you read the manual thoroughly, once you have any quires, please email or fax to ALIA
technical department.
D. Ensure all the specifications of instrument are in a normal state.
E. Power on to check whether the LCD screen operates normal.
F. Proper installation is required.
G. Install flowmeter and pipeline under installation instructions.
H. Connect wires and specially attention on whether they have been shielded or grounded.
I. Power on and check whether there is any current leakage (mind your own safety), then if it doesn’t display any flow
rate, please follow steps above again, particularly wiring, power supply and grounding. If problem remains, please
contact ALIA Technical Support center or local agency.
2. Product Overview
Based on Von Karman vortices theory, AVF7000 can be used to measure liquid, gas and steam, even liquid that has
slight particles inside or turbid liquid. It’s widely used in industries such as petroleum, chemical engineering, pharmacy,
paper making, metallurgy, electricity, environmental protection and food.
3. Working Principle
ALIA AVF7000 is newly stress-type flowmeter that’s based on von Karman effect. It’s made up of a whole body whose
internal diameter and nominal diameter are the same and a triangular bluff body inside. Flow will alternately generate
vortices when passing by a bluff body. The periodic shedding of eddies occurs first from one side and then from the
other side of a bluff body (vortex-shedding body), is called "Karman vortex street” whose frequency is proportional to the
flow velocity.
Vortices at both sides cause pressure pulsation, making probe to generate alternation stress. The built-in electronic in
probe generates electric charge due to alternation press. And amplifier transmits them into pulsating output signals
which are equivalent to vortex shedding frequency.
Sensor
d
F=St v/d
F—frequency of vortex shedding (numbers) hz
d—width of bluff body
v—fluid velocity
St—Strouhal number, dimensionless
The actual width of a bluff body within a specific vortex meter is fixed and a function of Reynolds, therefore, a constant.
In linear range, from detected frequency F, pipe’s velocity is known, then volumetric flow. The relationship between
frequency and volumetric flow is defined as below:
Q=3600 F/K
K: factor
F: frequency
Q: fluid volume under actual condition (m3/h)

6. Installation
Installation position of Vortex Flowmeter is very important. It concerns measuring accuracy. Please leave more space of
straight pipe in upstream and downstream as best as you can. If not permitted, please install as 2/3 of total straight pipe
length on the upstream and 1/3 on downstream. However, accuracy this time can not be assured as factory accuracy.
For example:

● Grounding
Good grounding is highly demanded so as to avoid signal interference. Please see below pictures, all you need to do is
to ground the displayer. And the sensor grounding is unnecessary. Grounding place is like stairs and railing.
To define whether vortex is well grounded initially, user need to check whether frequency is 50HZ or 60HZ or not. If it’s
always 50HZ or 60HZ, it means grounding is poor. Please see details in 9.2 to check frequency value.

9.3 Field Application
Two situations will frequently happen at site:
A. No flow, it displays value.
B. Flow, it displays zero.
Reasons for problem A: vortex get interfered by outside environment, keeping receiving interference signals. In the
picture below, interference signal is more than vortex’s threshold value. So vortex displays value. To solve this problem,
interference signal should be smaller than threshold value.
V
The Threshold
Interfering Signa
l
Reasons for problem B: flow frequency is very low, see the flow signal below. It’s lower than threshold value, leading
to measurement failure. To solve this problem, flow signal should be bigger than threshold value.
V
Flow Signal
The Threshold
Then how to adjust interference signal and flow signal?
The solution lies in signal amplification. Signal amplification adjustment is ”2000~2000000”.
Default amplification:
If measuring medium is liquid, it’s 5000.
If measuring medium is gas or steam, it’s 80000.
Amplification adjustment method:
☆ Magnification can be divined into two parts:
amplification factor and magnification gain.
Magnification factor is in “Max AMP”while magnification gain in “AMP. Channel”.
If amplification is 5000, amplification factor will be 500 and amplification gain 101 , namely 500*101 =5000.
Amplification factor Amplification gain
(Range: 200~2000) (CH1=101; CH2=102; CH3=103 )
☆To solve problem A: decrease amplification factor. Suppose amplification is 5000 now, change amplification factor
(Max AMP) as 400 but keep amplification gain (AMP.Channel) the same (CH1). Then amplification is 400*101 =4000. If
vortex still displays unusually, adjust amplification factor again.
☆To solve problem B: it happens to be on the contrary of A, namely adjust amplification from 5000 to 30000. Then:
Change amplification factor (Max AMP) as 300;
Change amplification gain (AMP. Channel) as CH2;
Amplification number is: 300*102 =30000
☆In conclusion, amplification has to be set according to actual condition, making vortex displays properly, namely it
displays zero when there is no flow and displays correct values when there is flow.

Low Flow Limit
Set by and keys. Theoretical min. flow rate, this parameter does not affect the measurement,
for reference only. Do not change it (if necessary, please contact ALIA).

Amplification factor
Set by and keys. What amplification factor corresponds to is the amplification factor of vortex
signal. Setting range: 0-2000, recommended range: 200-2000 (For air, standard default value is
800; liquid: 500) It can be adjusted by signal strength in Signal Monitor. It’s not recommended to
change Max.AMP. If necessary please contact ALIA engineer.
Press to enter next setting interface.
Max. AMP
500
K Factor (Pulse/m3)
Instrument calibration factor. Do not modify K-Factor, or measurement accuracy will be influenced.
