IEC 60325 Radiation protection instrumentation – Alpha, beta and alpha/beta (beta energy >60 keV) contamination meters and monitors; IEC 60329 Strip-wound cut cores of grain oriented silicon-iron alloy, used for electronic and telecommunication equipment; IEC 60331 Tests for electric cables under fire conditions – Circuit integrity
The meter comprised a moving coil meter, voltage and precision resistors, and switches and sockets to select the range. The first Avometer had a sensitivity of 60 Ω/V, three direct current ranges (12 mA, 1.2 A, and 12 A), three direct voltage ranges (12, 120, and 600 V or optionally 1,200 V), and a 10,000 Ω resistance range.
A Lease Automatic Custody Transfer unit or LACT unit measures the net volume and quality of liquid hydrocarbons.A LACT unit measures volumes in the range of 100 to 7,000 barrels (16 to 1,100 m 3) of oil per day.(*LACTs can transfer/measure more than 7000 bbls/day) This system provides for the automatic measurement, sampling, and transfer of oil from the lease location into a pipeline.
A turbine meter has a turndown ratio of 10:1. Rotary positive displacement meters have a turndown ratio of between 10:1 and 80:1, depending on the manufacturer and the application. Diaphragm meters are considered to have a turndown ratio of 80:1. Multipath ultrasonic meters often have a stated turndown ratio of 50:1.
A kilogram mass and three metric measuring devices: a tape measure in centimetres, a thermometer in degrees Celsius, and a multimeter that measures potential in volts, current in amperes and resistance in ohms.
A SMU integrates a highly stable DC power source, as a constant current source or as a constant voltage source, and a high precision multimeter.. It typically has four terminals, two for source and measurement and two more for kelvin, or remote sense, connection.
A current meter is an oceanographic device for flow measurement by mechanical, tilt, acoustical or electrical means. Different reference frames
The FCC has been published since 1966. Before 1960s, although the federal Food and Drug Administration (FDA) had by regulations and informal statements defined in general terms quality requirements for food chemicals generally recognized as safe (), these requirements were not published in the official regulations or designed to be sufficiently specific, therefore their use for general ...
