a switch that turns electrical current on and/or off.

An element located in a flowstream measuring the flow using electro-magnetic forces.

A flow transmitter that is specially designed to convert the signals from an electromagnetic flow meter into a standardized electrical output signal.

A controller that uses in-built algorithms executed by electronic circuitry to perform its function.

An electronic ac converter for changing the frequency.

An electronic converter that changes direct electric current to single-phase or polyphase alternating currents.

a radio beacon in the mobile service the emissions of which are intended to facilitate search and rescue operations (EPIRB).

A valve that is assigned to act in case of emergency.

An internal combustion engine that is an induction compression ignition exhaust engine which ignites a fuel air mixture.

A piping assembly intended to transport exhaust gas or steam.

A physical object that is intended to deliver or exhaust volumes of vapour or gas at low differential pressure.

Is a fired heat transfer equipment intended to burn fuel and to transfer the heat of combustion to a liquid without vapourizing the liquid.

A detector that is intended to sense a flame.

A specially designed switch with connections for inputs from multiple flame detectors. The switch has a built in logic to determine the presence of a flame based on these inputs.

An analysing instrument intended to determine the flash point of a substance.

A projector providing a beam of intense illumination.

A detecting element that is producing a signal that is proportional to a flow rate.

A gauge intended to indicate a liquid or gas flow.

A regulator that normally use the differential pressure principle across an orifice to control the valve trim and regulate flow.

A functional switch that is intended to give a signal when the flow have reached a pre-set value.

A totalizer that adds up flow measurements.

A flow transmitter providing an output signal that is proportional to the flow inputs from a flow element.

A device capable of detecting droplets of water vapour suspended in the air near the ground.

A vehicle with power operated prongs that can be raised and lowered by will, for loading, transporting and unloading goods; chiefly used in factories and warehouses.

An analyser intended to determine the freezing point of a liquid.
