1. DESCRIPTION

1.1. Application

1.1.1. "AFLOWT MF" electromagnetic flowmeter of “Pro-×××M×” model is de-

signed for measuring average volumetric flowrate and volume of vari-

ous electrically conductive liquids in a wide range of operating condi-

tions.

"AFLOWT MF" flowmeters can be used in a great variety of appli-

cations in power industry, oil, gas and mining industries, municipal en-

gineering as well as in iron and nonferrous, chemical, oil refining, cellu-

lose and paper, food and other industries. The flowmeters can be used

as a part of various integrated solutions, metering systems, automatic

process control systems etc.

The flowmeters can be installed in both metal, and plastic (metal-

plastic) pipes.

1.1.2. Depending on design type and firmware, "AFLOWT MF" flowmeters of

“Pro-×××М×” model perform the following functions:

- Measure average volumetric flow rate in either forward or reverse flow

directions

- Totalizing volume of forward and reverse flows independently or calcu-

lating their algebraic sum with regard to flow direction

- Batching of preset volume of liquid or in the start-stop mode, batching

and determining the amount of batched liquid, batching time and flow

rate

- Displaying measurement results and emergency conditions

- Outputting of measurement results to current, pulse or logical output

- Storing configuration settings in the Device’s non-volatile memory

- Automatic monitoring and displaying alarm conditions and faults

- Transferring measurement, diagnostic, configuration, log data etc. via

RS-485 serial interface

- Protecting configuration settings from unauthorized access.

The flowmeter is also capable of monitoring how the pipeline is

filled with liquid.

1.2. Specifications

1.2.1. The maximum Qmax, and the minimum Qmin flowrate values of meas-

ured average volumetric flowrates for various nominal diameters (DNs

of the flowmeter’s flow channel) are given in Table 1.

1.5. Design and operation

1.5.1. Operating Principle and Arrangement of the Flowmeter

The flowmeter consists of the primary transducer (electromagnetic

flow sensor) and secondary converter which is a microprocessor-based

electronic measuring block (MB).

MF operation principle is based on measuring electromotive force

(EMF) induced in electrically conductive liquid when it flows in magnetic

field. The magnetic field is furnished in the flow sensor's inner channel

by a special electromagnetic system (see Fig.1)

Fig.1. Flowmeter's block diagram

The Electromagnetic Flow Sensor is designed as a hollow magne-

totransparent cylinder with solenoid coils located outside. The inside of

the cylinder is covered with an electrically insulating material. The in-

duced signal is picked up by two electrodes, which are in conductive

contact with the liquid under control.

Inductive electromotive force (EMF) Eis proportional to the mean

flow velocity v, distance between the electrodes d(which is equal to the

sensor's inner diameter), and magnetic field strength B:

E = k B d v,

where k is a linear factor.

Band dare constants for the flowmeter of a given standard size.

The value of electromotive force (EMF) is independent of liquid temper-

ature and viscosity, and also it is independent of conductivity provided

that the value of conductivity is no less than specified in the flowmeter's

specifications.

Considering the formula for inductive EMF, flow rate Qis calculated
