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. 4-button user interface and graphical LCD display provide enhanced depth of data, indicating on-screen waveforms and troubleshooting tips. 4-20 mA output Rotatable housing can be dismantled without depressurising the vessel via “Quick connect/disconnect” probe coupling. Ergonomic dual compartment enclosure Simple set-up and configuration Smart Probe Technology Easy attachment to an MLI Direct insertion for a wide variety of vessels and applications OPTIONS HART® digital communications Hastelloy® or Monel® materials of construction Threaded or flanged process connections External Jupiter models can be top or bottom mounted to an MLI
