Electromagnetic flowmeter - LDB

Electromagnetic flowmeter

Type :LDB

Filter grade : NO.1

1.Measure principle:
Electromagnetic flowmeter is made on the basis of Faradays law of electromagnetic induction. when the measured conductive medium moves for cutting magnetic line in magnetic field, inducing emf in conductive medium,induced emf measured by a pair of electrodes,and use the following equation:

K:Proportional constant; B:Magnetic flux density;

D:Measurement of tube diameter; :Measuring the average velocity inside the pipe section

After E-signal device being processed,the output and proportional flow to the frequency of pulse signal 0-1000Hz,and analog current 4-20mADC or 0-10mADC for the follow-up instruments(such as flow totalizer display and control instrument,etc) used to complete the flow test.

2.Product characteristics:

Low-frequent three-valued-wave constant current excitation.

Use of closed-loop machine technology and computer technology,the instrument work is very stable and reliable.

In the field can be modified according to the actual needs of the user range,and has re-zero function of the air traffic control.

No moving parts,no choke parts,no pressure loss in measure.

Measurement results independent of medium temperature,density,pressure,viscosity and other physical parameters.

separated structure and body structure,easy to install.

3.Applications:

It is widely used in environment protection,factory drainage,urban water supply and drainage,paper,sugar,steel,petroleum, pharmaceutical and other industries to measure the water,sewage,fiber pulp,beer.,etc. medium volume flow.
