A pump that utilizes a liquid annulus held by centrifugal force around the inside of a casing by a single rotor-impeller to compress vapour isothermally.

A relief valve that is used for pressure compensation purposes by admitting (letting in) a pressure to prevent that vacuum is forming when filling or emptying a system.

A fluid regulator that can be used to control (i.e. permit, obstruct, regulate or divert) a fluid stream.

An analyser intended to determine a vapor pressure.

A physical object that consists of an electric motor and controller that is used to adjust the motor's operating speed.

An Area designed to facilitate safe and secure storage of hazardous materials.

A physical object that is any conveyance (usually wheel, e.g. a cart, lorry, motorcar, but also a sledge) for goods or passengers on land.

A breather that discharges gas to the atmosphere at low velocity, and that is intended for vertical connection to a vent pipe

A pipe or tube that has a constriction with a relative long passage with a smooth coned entry and exit.

A container intended for storage and/or processing of fluids.

A conveyor that is a tubular or flat trough with slides, to which vibrators are attached. The latter impart an upward and forward conveying movement to bulk materials in the trough.

A detecting element that is intended to sense mechanical vibration and in which the oscillating motion is transferred into a voltage or current signal.

A switch intended to give a on/off signal when vibration level have reached a pre-set value.

A transmitter of which the output is proportional to a measured vibration.

A signal converter intended to convert one video signal type to another video signal type.

A facility with the capability of receiving video signals and displaying pictures.

A recording instrument that is recording signals originated by a TV camera on a moving magnetic tape for subsequent reproduction or transmission.

A type of portal designed to enable a safe but limited view into a hazardous area.

An analysing instrument intended to determine the viscosity of a fluid.

A regulator designed to automatically maintain a constant voltage level.

A signal converter that is intended for converting an input voltage signal into an output current signal.

An instrument transformer in which the secondary voltage, in normal conditions of use, is substantially proportional to the primary voltage and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.

A transmitter which output is relative to a measured voltage.

A flow meter that measures the velocity of a fluid in a pipe by detecting the frequency of vortices being shed from a specially shaped obstructing element in the fluid stream.

A transmitter specially designed to convert the signal in a vortex flow meter into a standardized output signal.
