METHOD FOR DETERMINING THE LEVEL OF LIQUID magnetostrictive level gauges and level gauges MAGNETOSTRICTIVE

摘要

1. A method for determining the level of magnetostrictive liquid level gauge, comprising feeding the excitation pulse to the coil of the excitation coil, measuring a first time interval from the moment the pulse excitation coil winding until the formation of lines of electrical oscillations in the piezoelectric transmitted from the twin-turbo float magnets, and determining the liquid level, characterized in that the temperature measurement end produces acoustic conductor immersed in the liquid, given the measured temperature is determined ck the velocity of sound in the acoustic line at the site of installation point to the magnets of the float, measuring a second time interval from the moment the pulse in winding the excitation coil until the formation reflected from the end of the wire electric oscillations in the piezoelectric, and determine the distance from the end of the acoustic line transmitter to a liquid level difference second time interval and the first interval vremeni.2. A method for determining liquid level magnetostrictive level gauge according to claim 1, characterized in that the control is determined as a sum of the first and second time intervals in the absence of interference, and all measurements in the presence of interference that do not satisfy the checksum otbrasyvayut.3. Magnetostrictive transmitter comprising a transducer, a sensor placed in a twin-turbo dielectric tube of magnetostrictive material, excitation winding coil wound around the dielectric tube, a float with a magnet arranged around the insulating sheath movably therealong, determining unit level n
