An 'equipment class' that is a class of devices engaged in meteorological observations

An artefact for the calibration of flow meters.

A device that is capable of three-phase metering of liquid, oil and gas.

A microphone, sometimes called a mic (pronounced mike), is a device that converts sound into an electrical signal.

Structure used to support and restrain flexible risers.

An equipment class that contains classes that not covered by any other parent class.

A physical object intended to be used for fluid mixing processes typically a rotating piece of equipment comprised of a driver such as a motor which rotates an agitator immersed in the fluid(s) that need to be mixed.

An aerial work platform (AWP), elevating work platform (EWP), or mobile elevating work platform (MEWP) is a mechanical device used to provide temporary access for people or equipment to inaccessible areas, usually at height.

Short for modulator/demodulator. A communications device that converts one form of a signal to another that is suitable for transmission over communication circuits, typically from digital to analogue and then from analogue to digital.

A gas flow damper that is able to stay in any position between fully open and fully closed.

A device that generates rotational kinetic energy.

A switchgear and controlgear that houses motor starters to control electric motors.

An operated valve that is opened and closed with a motor.

Is a bracket intended to attach an item to another item.

An analyser giving as output a signal that represents more than one physical properties of the analysed substance.

A flow meter for the metering a mixture of two or more fluid phases.

A valve not designed to regulate flow (e.g. on/off). A valve with multiple orifices or flow-restriction device to control fluid flow. Includes an actuator that needs auxiliary power to operate.

Is an artefact intended for a number of input channels to share one output channel.

A valve not designed to regulate flow (e.g. on/off). A multi port valve which has the possibility of multiple distinct paths for flow through it. Includes an actuator that needs auxiliary power to operate.

A valve that has three or more ports arranged to switch flow.

A needle valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

A globe valve that has a closure member with the shape of a conical plug (needle) which closes into a small seat.

A very accurate flow meter used to record oil exports.

A gas flow damper that prevents back flow in a duct.

A physical object that has a protruding part through which a stream of fluid is directed.
