is a process unit with gentle agitation used to bring together fine particulates in wastewater into larger clumps or flocs through physical contact to enhance the subsequent separation and removal of solids in sedimentation basins.

A projector providing a beam of intense illumination.

A level contained within a building or industrial compound, that provides safe access and a stable working or operational area for internal structures, equipment & personnel.

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 detecting instrument intended to measure and indicate flow rate and/or produce a signal which represents the measured flow rate.

An orifice plate which restrict the flow and thus develops the differential pressure that is proportional to the square of the flow rate.

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.

Equipment used to direct foul water flow.

Materials used to transfer loads to the ground and maintain structural stability.

A physical object that is an open structure of beams or bars.

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

A device that generates an electrical signal of a specified frequency.

A signal converter that is intended to convert a frequency or rotational speed input signal into a 0 - 20 mA or 4 - 20 mA current output signal.

A hollow cone with a tube extending from the smaller end and that is designed to catch and direct a downward flow.

A physical object that is intended to induce a reaction in a process fluid by heating it.

Is an artefact which is necessary, useful or desirable, especially for living or working but is not a tool for production.

A physical object that by the fusing of one or more of its specially designed and proportioned components, opens the circuit in which it is inserted by breaking the current when this exceeds a given value for a sufficient time.

A plug capable of being melted and fused.
