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.

A wafer pattern valve that is a check valve with a wafer pattern valve body.

Which is flat and typically vertical suitable for separation.

A compactor is a machine or mechanism used to reduce the size of waste material.

A water cooler is a device that cools and dispenses water.

Is a fresh water system.

A device for producing drinking water, but not necessarily by reverse osmosis.

A skid assembly containing the units required to operate a water mist system.

A transmitter for weighing large quantities of material, and of which the output is proportional to the measured weight.

A physical object for arc welding, either ac or dc, comprising a supply unit and a regulator.

A well is a collection of (zero or more) holes drilled into the Earth for the purpose of either (1) finding or producing underground resources; or (2) providing services related to the production of underground resources.

The wellhead is assembled from, or incorporates facilities for, the upper casing and tubing hangers. This effectively provides the upper termination of the wellbore and provides a mounting position for the surface flow-control equipment or Christmas tree.

A power transformer of which the magnetic circuit and windings are immersed in oil.

A powerful machine with one or more drums on which to coil a rope, cable, or chain for hauling or hoisting.

A detecting element that can be the sensing element of an anemometer or wind gauge.

A turbine that converts the kinetic energy of the wind into electrical power.
