1.2 Principle of Operation
The Alpha4000 Area Velocity Flow Meter uses a submerged 1 MHz Doppler sensor and a non-contact 47kHz ultrasonic level sensor, measures level and velocity in two channels and calculate flow based on the current level and the formula: Wetted AREA multiplied times VELOCITY equals flow.
It’s one of your best options of flow measurement for open channel and non-full pipe without primary device. The portable version could be a Portable Velocity Meter for short term flow studies and sanitary sewer evaluation studies.
Alpha4000 measures average velocity directly, without the need for time consuming flow profiling, significantly reducing the cost of installation and operation.
1.3 Typical Applications
The measuring device described in this Operating Instruction is to be used only for measuring the flow of fluids in closed pipes. -Acids, alkalis, paints, oils, etc. -liquefied gas, solvent, etc.
-Ultrapure water with low conductivity, water, wastewater, etc.

1.4 Flow Measurement Techniques
Under the competitive industrial environment, the efficiency of a manufacturing operation is directly linked to the profitability of a company. In companies where the daily operations involves the use of liquids, the measurement of these components is necessary. The ability to make accurate flow measurements and control the process will contribute to the success of a company's operations. Plant safety, process control, production output and leak detection are typical reasons to measure the flow of fluids.
Many flow measurement instruments, determine the flow rate indirectly by measuring the velocity or depend on the pressure differential that is forcing the liquid through a pipe or conduit. Because the pipe's cross-sectional area is known and remains constant, the average velocity is an indication of the flow rate. The basic relationship between the flow rate and liquid flow in such cases is:
QVA
Where:
Q = liquid flow through the pipe V= average velocity of the flow A= cross-sectional area of the pipe
6
ALPHASONICTM Alpha4100
In the above calculation formula, A is measured by the level-sensor as below cases: When liquid level below the center of the pipes:
A22R2RHRsinRRRHsin2
When liquid level above the center of the pipes:
A222R2HRRsinRRHRsin2
Where
pipe level H
RHR arccos7
ALPHASONICTM Alpha4100
Reynolds Numbers
Factors that affect flow rate include the viscosity , density, and the friction resulting from contact with the pipe.
A flow meters performance is influenced by a dimensionless number called the Reynolds Number. It is defined as the ratio of liquid's inertial forces to its drag forces. The equation for liquid flow is:
R3160QgpmSG
DUcpWhere:
R = Reynolds number Q = flow rate
SG = liquid's specific gravity D = inside diameter of the pipe U = Viscosity in centipoises
The rate of flow and the specific gravity are inertia forces, and the pipe diameter and viscosity are drag forces. The pipe's inside diameter and the specific gravity remain constant for most liquid applications. At very low velocities or high viscosity, R is low, and the flow runs in smooth layers with the highest velocity at the center of the pipe and low velocities at the pipe wall where the viscous forces restrain it. This type of flow is called

ALPHASONICTM Alpha4100
laminar flow and the R values are below approximately 2000. A characteristic of laminar flow is the parabolic shape of its velocity profile. Many applications involve turbulent flow, with R values above 4000.
Turbulent flow occurs at high velocities and/or low viscosity. The flow breaks up the same average velocities in the center of the pipe as well as those near the pipe wall. Under these conditions the velocity is less significant, and the velocity profile is much more uniform in shape. A transitional or critical zone exists between turbulent and laminar flows (R#'s 2000-4000 typically) Depending on the piping configuration and other installation conditions, the flow may be either turbulent or laminar in this zone.

2.2 Operation Factors
The most important factors to consider for successful operation are:
1) The sensor coupling which allows the maximum signal strength to pass from the sensor to the liquid.
2) The density or amount of particles in the fluid to reflect the sound waves.
3) The coupling ability of the pipe walls. Normally old pipes have encrusted material built up on the inside walls and tend to absorb part of the sensor signal. Plastic lined pipes have a similar effect.
2.3 Sensor installation

The input diameter is not matched with the inside diameter. 2. Modify the pipe diameter, make it well to be matched. 1. There are painting, rust, on the out side of the pipe. 2. There are rough on the pipe or the sensor was mounted on the brazing seam. 3. The pipe don’t has good roundness pass and the inside surface don’t smooth. There are grime on the liner. Usually the cast iron pipe has this application. 4. The measured material is pure or the solid suspension are few. 5. The transducer was mounted on the 43
The sensor work well but the flow velocity is too slow or no flow velocity. 1. Clear the pipe again and mount the transducer. 2. Rubdown the rough or far from the brazing seam. 3. Choose the steel pipe with smooth inside surface or don’t has liner. 4. Choose other meter. ALPHASONICTM Alpha4100 fiberglass pipe. 6. The transducer was mounted on the bush ,it will eliminate the ultrasonic signal. 7. The transducer is not coupling well with the pipe, there are blind side or bubble on the hookup surface. When close part of The transducer was mounted too closed the valve or reduce near the control valve, when close part of the flow, the reading the valve the pressure difference between increased contrarily. the two sides of the vale was increased. 5. Remove the fiberglass. 6. Move the transducer to the location where don’t have the bush. 7. Reinstall the hookup dose. Mount the transducer far from the control valve.
