The taut-band movement is a modern development of the D'Arsonval-Weston movement. The jewel pivots and hairsprings are replaced by tiny strips of metal under tension. Such a meter is more rugged for field use. [5] [6]
The meter movement in a moving pointer analog multimeter is practically always a moving-coil galvanometer of the d'Arsonval type, using either jeweled pivots or taut bands to support the moving coil. In a basic analog multimeter the current to deflect the coil and pointer is drawn from the circuit being measured; it is usually an advantage to ...

Certainly manufacturers of one-band and two-band mobile equipment prefer to support 2m and 70cm first (in that order) to reach the largest number of users, but once those start to become full, any spillover into a third band must go (for want of other similar frequencies) to 50MHz or to 220. --66.102.80.212 20:21, 27 March 2009 (UTC)
Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...
Magnetometers are capable of detecting large objects, such as cars, at over 10 metres (33 ft), while a conventional metal detector's range is rarely more than 2 metres (6 ft 7 in). In recent years, magnetometers have been miniaturized to the extent that they can be incorporated in integrated circuits at very low cost and are finding increasing ...
A price band is a policy instrument that serves to insulate domestic producers and processors when the world price for a commodity falls below a calculated reference price (e.g., a price target comparable to a commodity support level).
