Simulation magnetostrictive liquid level meter (A+E-68L)

A+E 68L Analog Magnetostrictive Liquid Level Probe uses 16-digit D/A converter,
4-20mA output signal, which is mainly used for precision measurement of liquid
Level, interface and temperature in the industrial process of oil refining and chemical
Engineering.

This probe uses magnetic pulse wave. The head of the liquid level meter (upper part
Of the tank) will transmit electricity of "Interrogation pulse", and this pulse will generate
A magnetic field simultaneously, which moves downward along the induction line within
Waveguide duct. There is a floater out of the level meter tube, which can move up and
Down with liquid level and side-bar. There is a set of magnets hiding in the floater and a
Magnetic field is generated, the two magnetic fields encounter and a new variation magnetic
Field is generated so a new "Return pulse" is produced subsequently. We can know the liquid
Level position by measuring the period of "Interrogation pulse" and "Return pulse". The only
Moveable part of this liquid level meter is the floater, so there will be little maintenance involved
And easy installation, and high accuracy. Another characteristic is that it can measure the
Temperature at the same time, but it is unsuitable for measuring heavy fuel oil.
