Jupiter® JM4 magnetostrictive level transmitter
The Jupiter® JM4 liquid level transmitter is a loop-powered 24 VDC liquid-level transmitter and is available as a direct insertion transmitter or as an external mounted transmitter onto a Magnetic Level Indicator. It relies on the position of a magnetic float which is designed precisely for the liquid to be measured. This high-accuracy device can be designed for liquid level and/or liquid-liquid interface measurement.
The high safety level of JUPITER is demonstrated by a Safe Failure Fraction > 90 %
Magnetostrictive
A low-energy pulse, generated by the JUPITER electronics, travels the length of the magnetostrictive wire. A return signal is generated from the precise location where the magnetic field of a float intersects the wire. A timer precisely measures the elapsed time between the generation of the pulse and the return of the acoustic signal. Each cycle occurs ten times per second, providing real-time and highly accurate level data.

Applications
Operating principle
Jupiter operates on the Time-of-Flight principle. A low energy pulse, initiated by the transmitter electronics, travels the length of the magnetostrictive wire 10 times per second. A return signal is generated from the precise location where the magnetic field of a float intersects the wire, resulting in a mechanical wave response. A timer precisely measures the elapsed time from the generation of the pulse and the moment each return wave is captured by a piezoelectric sensor.
