There is no particular instrument used for measuring tornado intensity. Ratings are based primarily on damage assessment. Occasionally doppler radar has measure wind speeds inside a tornado, but such measurements are rare.
In most cases the intensity of a tornado is never actually measured. Tornadoes are rated based on the severity of the damage they cause. Mobile Doppler radar can measure wind speeds in a tornado, but since such radar cannot measure ground-level winds the measurements are not used in ratings.
There has never been a tornado name Sheila as tornadoes are not given names like hurricanes are. The name Sheila is included on the list of tropical cyclones (generic for hurricanes, typhoons, etc.) in the area of Fiji and was used once, but the storm only reached equivalent to tropical storm intensity.

Unlike hurricanes, tornados are not named.

A volt meter
There is no single instrument as there are different types of natural disasters with different things that can be measured. Anemometers, barometers, and rain gauges can measure wind, pressure and rainfall in storms. A seismometer can measure the intensity of a earthquake.
Pressure gauge or tachometer.
Electrical current can be measured with an Ammeter. The units used are amps.
Meter is the general name for any measuring instrument. Such as an electricity meter, or an odometer on your car. But if you mean the metre as in measuring systems, then surveyors, mountaineers, engineers, and so on.

Another name for a tornado is a twister.
Tornado is the proper term.
