A pressure vessel located in both pump- and compressor piping systems in order to reduce residual pulsation fluctuations, as a result of discontinue operation effects, within an allowable level specified.

A physical object that adds or removes mechanical energy to a fluid, either constantly or periodically.

An aboveground drive for a reciprocating piston pump in an oil well.

A manual control switch that is intended to switch when you push or touch the button.

A mechanical structure intended to receive a number of pieces of basically standardized modular equipment.

A physical object for detecting the presence of objects at a distance, or ascertaining their position or motion, by transmitting short radio waves and detecting or measuring their return after being reflected.

An element intended to determine a level based on high frequency electromagnetic waves.

A level transmitter that is producing a standardized electrical output signal based on the input signal from a radar type level sensor.

A personal radiation monitor is a device that detects the presence of any radiation sources.

Is a heat exchanger which cools a fluid and heats the surrounding environment.

A radio transmitter, usually non-directional, that emits identifiable signals intended for radio direction-finding.

A mobile radio communications centre.

A transceiver which has the methods of signalling through space, without connecting wires.

A level transmitter that is producing a standardized electrical output signal based on the input signal from radioactive level measurements.

A signal at a railway grade crossing that indicates the approach of a Locomotive.

A safety system to govern the use of single rail tracks to ensure only one locomotive can use the track at any one time. The rail key token station controls the issue of key tokens permitting movement.

A physical object that consists of two parallel steel rails, generally anchored perpendicular to beams or railroad ties of timber, concrete, or steel to maintain a consistent distance apart, to facilitate transport on the rails with vehicles arranged in a train without the need for steering.

A sloping surface joining two different levels, as at the entrance or between floors of a building.

Is a piece of hardware intended to read and decode information encoded on a carrier.

A positive displacement compressor in which forced reduction of gas volume takes place by the movement of a displacing element in a cylinder or enclosure.

A positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.

A process instrument that records values represented by the input signal(s).

An electric converter for converting an alternating current into a direct current.

A recuperator is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat.

An analyser intended to determine the oxidation and reduction capability of material.
