Product Description Electromagnetic FlowmeterWorking principleIts measuring principle bases on Faraday electromagnetic induction law:When the liquid flow through the measuring pipe which all around magnetic field, the two vertical direction will have the induced electromotive force which is proportional with the mean velocity of stream.Flowmeter consists of sensor and converter. Converter transfer field current to inner loop of the sensor to engender magnetic field. Conductivity liquid flow through the measuring pipe and get induced force because of cutting magnetic line. By then the electrode around the pipe wall incept induced force and transfer them to converter through signal wire. Converter filer induced force, spread, calculate and exchange them into proportional standard current signal and frequency signal. Brief introduction1.it can measure all kinds of electronic conductivity liquid, such as corrosive liquid , mud and slurry ,water etc. 2.The result cannot be affected by temperature, pressure, viscosity and dens ity.3.Flow sensor and intelligent converter compact or separately composes a com plete flowmeter. Main features1.No move assembly, no abrasion 2.Measuring range rate: 1:1003.No flow enhance equipment4.Suits for various of electronic conductivity liquid5.No affect from temperature, viscosity, pressure and density6.Anti- corrosion7.Measure both to and reverse flow8.Huge display, easy operate9.Long- term EEPROM to save data when lose power10.Support MODBUS/HART communication protocol11.Wide working volts range12.Self diagnose Parameters:DN6mm~~2000mmPNPN6 , PN10 , PN16 , PN25 , PN40 , PN63 , PN100 , PN160 , PN250 , PN420Electrode material316LLining materialPTFE or customizeMedium tem0~70°C , max is 180°CShell materialcarbon steelProtection gradeIP65 , IP67 and IP6Connectionall applys( eg : BS EN1092-1 )Converter technical data Current output4~20MaFrequency outputNo resource pulse : High level=external power supply-1V External volts≤30 V Low level ≤ 0.5V Load current ≤ 50 mA Max.frequency output :5KHz .
