Magnetorestrictive Level Transmitter. These transmitters operate using magnetorestrictive sensing material, usually in the form of a coiled wire. The sensing wire is pulsed with a current at fixed intervals to create a magnetic field which then interacts with the float's magnetic field, which is in direct relation to the liquid level. This creates a stress in the sensing wire. This stress wave propagates along the sensing wire at sonic speed until the pulse is detected at the transmitter. The measured lapse time is then converted into an analog output proportional to level. These devices have high sensitivity and dynamic range, no measurable mechanical hysteresis, a linear response, and physical robustness. They are ideal for continuous level monitoring of storage and shipment containers for oil, beer and other beverages, pharmaceuticals, flammable fluids, solvents, and hydrocarbons.
