“…Prior to calibrating the F-STAr EMFM, the conduit walls were wetted to ensure good contact between the sodium, inner conduit wall, and external measurement leads. Experience with sodium has shown that it has poor initial surface wetting characteristics [22]. This will impact the electrical resistance between the sodium and the measurement leads, which will therefore impact the measured signal.…”

“…To control the level of metal melts, it is customary to use multipoint signaling devices based on compact inductive transducers and inductive level gauges (Leshkov andTaranin 2008, Taranin 2015), as well as potentiometric devices operating on the principle of measuring the resistance of a tubular probe immersed in metal (Trakhtenberg and Deniskin 1967). Most of these developments were carried out decades ago, and are characterized by extremely high cost and low reliability (Kirillov et al 1960).…”

The article presents the results of work aimed at solving the problem of measuring the coolant level in miscellaneous tanks of liquid-metal-cooled reactor plants, mainly of an integral layout with a free level of the primary coolant. The choice of relevant measuring means and methods is limited by the extreme parameters of the liquid metal coolant (LMC) and operating conditions. Traditional measuring means are practically unsuitable; therefore, measuring the HLMC level is a complex technical task. Based on this review, they propose and describe a method of pulsed microwave reflectometry as the most promising in terms of combining the characteristics of reliability, accuracy and ease of use. The results of the experimental study demonstrated the efficiency of the level gauge, which worked according to this method, for measuring the level of lead-bismuth coolant in the control tank under conditions close to natural ones. An analysis of the results confirmed the possibility of using this method to control the level of melts of various metals as applied to HLMC reactor plants. Using the device for measuring the level, which works according to the proposed method, it is possible to control the level of melt of various metals in tanks in real time without the need to move various parts of the sensitive element of the level gauge while maintaining the tightness of the circuit. This device is applicable for various nuclear power plants, accelerator-controlled systems, research reactors and experimental facilities with liquid metal coolants.
