“…This figure illustrates the polarities at a fixed time in a cycle [3]. If the eddy current flowmeter sensor is placed in a flowing sodium, the induced voltages in the both the secondary are not equal because the induced voltage is subtractive to transformer voltage in upstream secondary coil and additive to transformer voltage in downstream secondary coil hence the resultant voltage is proportional to sodium flow [7,10]. …”

“…Also the overall average sensitivity of dry test housing was 44% of that in wet test housing. In PFBR the ECFM was subjected to sodium testing in two phases where flow was measured with reference to a permanent magnet flowmeter [7]. In first phase testing the shield material used was Fe-Ni tube and in second phase SS410 tube.…”

“…The phase I testing was performed with constant primary excitation of 200mA, 433Hz.The testing was done at various sodium temperature ranging from 250ºC to 500ºC.The secondary outputs were recorded for different sodium flow rates from 0 to 30 m 3 /hr. In phase II testing the sodium flow rate was made constant at 20 (m 3 /hr) and at 300ºC.The secondary outputs were recorded at different excitation frequencies from 200Hz to 1000Hz [7].The procedure were repeated for various sodium temperatures of 400 ºC and 500 ºC. From the test results it was found that the sensor with pure iron former surrounded by SS 410 shield gives good signal output.…”

“…The result exhibited a low eddy current generation in the down stream coil than in upstream coil. Veerasamy et al [7] compared the calculated value from FEM analysis with the actual measured values in sodium and inferred that the differences in these values could be attributed to variation of the properties with temperature.…”

Measurement of flow in liquid metal systems exhibit unusual problems because of the severe operating environments like high operating temperatures and the chemical reactivity of most liquid metals. The liquid metal flowmeters should have the capacity to withstand high gamma radiation levels and rapid thermal transients. The commonly used flowmeters in liquid metal systems are permanent magnet Flowmeter, direct current electromagnet Flowmeter and alternating current electromagnet flowmeter. In Alternating current electromagnet Flowmeter there are three types namely transverse field Flowmeter, Eddy Current Flowmeter and E-Core Flowmeter. The subject of analysis is the Eddy current Flowmeter. Eddy currents are generated when a moving conductor experiences changes in the magnetic field generated by a stationary object, as well as when a stationary conductor encounters a varying magnetic field. A flowmeter which works on this principle is the Eddy Current Flowmeter. This paper gives a thorough survey on eddy current flowmeter, its construction, simulation results and its performance under various test conditions in different organization
