Electromagnetic Flowmeter – WINTERS

LMF series of electromagnetic flowmeter SMD devices and surface mount (SMT) technology, circuit reliability, low power consumption, and the use of 32-bit embedded microprocessor, fast computing, high precision, low frequency rectangular wave excitation. The stability of the measurement. All digital processing, anti-interference ability, reliable measurement, high precision.

Ultra-low power EMI switching power supply, the use of a wide range of power supply voltage changes, EMC performance. Built-in three integrators, respectively, for positive cumulative, inverse cumulative and the difference calculation. With the average flow of automatic computing function, easy to calibrate the instrument.

At the same time also has a small signal cut off the function, the user can set the lower limit of the display panel and the lower limit of the flow, thus removing the interference of small signal flow. In order to enhance the safety, the flow meter is also equipped with a password latch function. After power meter, if you need to set parameters, you must enter the advanced password to set the parameters to prevent unauthorized personnel to change the instrument parameters.

Even if incident suddenly power failure, the flow meter operation results and user settings will not disappear, EEPROM can protect the set parameters and cumulative value.

Classification of Electromagnetic Flowmeter WINTERS

LMF series smart electromagnetic flow meters consist of  sensor and smart signal transducer. And it can be classified  into two structures— integral type and remote type according to the set-up form of the sensor and transducer. In terms of integral type electromagnetic flow meters, transducer and sensor directly assembles as a full ball type and can not be dissociated.

External power supply and Battery operated type is available  as following model.

Working principle of Electromagnetic Flowmeter WINTERS

The metering system of the electromagnetic flow meter primary is based on Faraday’s laws of electromagnetic induction, on the channel border which is vertical each other with metering tube axis and line of magnetic field mount one pair detecting electrode, when the conductive liquid move along the metering tube axis the conductive liquid cutting the line of magnetic field induce the inductive E.M.F. This EMF detect out by two electrodes on the metering tube, numerical value size is:

E=KBVD
Here:
+ E: Inductive EMF
+ K: Instrument constant
+ B: Magnetic induction
+ V: Average flow velocity in metering tube section
+ D: Metering tube inner diameter

When measuring flow rate, the fluid flow through magnetic field vertical to flow direction, the conductive liquid movement induce one EMF in direct proportion to average flow velocity, so that require measured flow liquid conductivity higher than lowest limit. It’s induction voltage signal is detected by two electrodes, and pass through a cable transmit to converter, after through signal treatment and correlative operation, take the integrating flow and the instantaneous delivery indicate on the display screen of the converter.

The sensed signal voltage is converted into the indexing, analogue, and digital output signals in the converter.
