WORKING PRINCIPLES
2.1 Measuring Principles
The measuring principle of electromagnetic flowmeter is based on the electromagneticinduction law of Farady. The sensor is mainly composed of measuring tube with isolate lining, apair of electrodes installed by penetration of the measuring tube wall, a pair of coils and ironcore to produce working magnetic field. When the conductive fluid flows through the measuring

tube of the sensor, the voltage signal in direct proportion to the average flow velocity of the fluidwill be inducted on the electrodes. The signal is amplified and treated by the transmitter torealize various display functions.

Converter Circuit Schematic
The converters supplies a stable exciting current to the coil in the sensor of electroneticflowmeters to get B constant and amplifies the electromotive force and convert it into standardsignals of current or frequency so that the signals can be used for displaying, controlling andprocessing. The schematic of converter circuit is shown in Fig. 2.1.

PRODUCT CLASSIFICATION
3.1Product components
Electromagnetic flowmeter is composed of sensor and converter. The remote-type also needsa special double-layer shielded cable to connect the converter and the sensor.
3.2Product models
SHM Meters electromagnetic flowmeter has two forms: compact-type and remote-type.
There are seven kinds of electrode materials and four kinds of lining materials available for
sensor.

OPERATION

a. There is any damage caused by transportation or installation;
b. The power used is same as the label on the flowmeter;
c. The wiring is correct.
After inspection, turn the valve on to fill the pipe up and make sure there is no leakage andthe gas inside the pipe is eliminated. Switch on the power supply and the flowmeter is ready touse after 10 minutes warm-up.
If there is any problem,
