Abstract: Methods and apparatus are for storing and retrieving data related to the installation, service, repair or performance of an industrial flow meter or other measurement instrument. Methods and apparatus are also for other processes associated with measurement instruments.

Abstract: An industrial meter has wireless communication circuitry for communicating with a remote communication device. A repeater device allows the wireless communication circuitry of the industrial meter to continue to communicate with the remote communication device when the meter device is positioned in a location where direct communication between the wireless communication circuitry and the remote communication device is not possible (such as for example when the industrial meter is located underground).

Abstract: A vehicle headlamp system including at least one headlamp switchable between at least a high beam mode and a low beam mode by a biased actuator movable by a driver of the vehicle, a headlamp arranged to emit a flash when the biased actuator is moved to a temporary-on position, and means for limiting the maximum duration of the flash to less than 2 seconds.

Abstract: A headlamp system for a vehicle comprises: at least one headlamp which is switchable between at least a high beam mode and a low beam mode, in which the headlamp emits a high beam and a low beam respectively, and wherein said high beam is of higher intensity than said low beam; a biased actuator which is movable by a driver of the vehicle between a temporary-on position and an off position, and which is biased from said temporary-on position to said off position; and a headlamp which is arranged to emit a safety flash when said biased actuator is moved to said temporary-on position; wherein the overall duration of the safety flash is automatically limited to a value which is less than 2 seconds.

Abstract: A method of determining the inter-electrode or electrode-to-ground impedance or the filling state of an electromagnetic flow meter having flow sensing electrodes connected to an electrode signal amplifier, the method comprising applying a test input signal to the flow sensing electrodes via a connection through which an output flow measurement signal of the flow meter is transmitted from the amplifier, in a manner such that the output of the amplifier is indicative of the said impedance or the filling state.

Abstract: A method of obtaining a plurality of measures of quantity of a substance flowing through a respective plurality of conduits is disclosed, wherein each of the conduits is supplied from an upstream common source location. An improved series of measurements are derived from an upstream absolute measure and downstream relative measures.

Abstract: In order to reduce the influence of fluid velocity on a measurement of a concentration characteristic of a fluid, the magnitude of an r.m.s. signal V derived from a voltage induced in a sensor provided in relation to the fluid passage is adjusted using a factor dependent upon the measured velocity v of the fluid. Consequently, the accuracy with which the mass flow rate M of the solids in the fluid can be determined is improved.
