Equipment
Equipment that requires this document type.

A devices that measure and communicate water usage from consumer to provider to facilitate water management and proper billing.

A detector that is intended to sense smoke.

tag class

An electromagnetic coil, which is a cylindrical coil, the length of which is much greater than its transverse dimensions and which is used to produce a magnetic field.

A valve that has linear action which is fitted with a solenoid for quick operation.

An analyser intended to determine a mixture of solid particles in liquids or solid or liquid droplets in air.

A meter intended to measure a sound pressure level.

An analyser intended to determine specific gravity's of materials. Typically of liquids.

tag class

A switch intended to give a on/off signal when the speed have reached a pre-set value.

A transmitter that is producing a standardized output signal dependent of a received input signal from a rotational speed sensor.

Is a support (item) intended to carry the load of piping components.

tag class

Is a support structure intended to support a flare or vent pipe.

tag class

A physical object that is intended to mix fluid by means of diverging the flow with static obstacles or by increasing locally the velocity.

tag class

A thermodynamic turbine in which steam is made to do work by expanding so as to create kinetic energy by acting on moving blades attached to a disc or drum.

tag class

A filter that is separating solid particles from a fluid by passing the fluid through a wire mesh, screen or metal plates containing perforations or slits.

A check valve that is a check valve where the closure member is a disc which swings freely on a hinge and which opens automatically when flow is established and closes automatically when flow ceases or is reversed.

tag class

An instrument panel dedicated to a particular system.

tag class

A fluid regulator that controls the flow of liquid or gas from a pipe or container. Taps are often attached to a sink or bath.

A detector intended to detect temperature.

A detecting element intended to sense temperature.

A gauge that is intended to measure and indicate a temperature.

A physical object that detects temperatures; records, modifies and/or displays or performs a combination of these activities.

A regulator that is intended to keep a temperature within certain boundaries.

A functional switch that is intended to give an on or off signal when the temperature have reached a pre-set value.

Registers
Registers where this document type is included.
A collection of all instrument set points and/or alarms. Each instrument having an alarm or trip function is listed. Alarms and settings are given as percentages of transmitter range and in engineering units, together with transmitter range, location of the annunciation point, cabinet, identification and relevant P&IDs/PEFS or logic drawing.
An authoritative collection of values with a relationship to instrumentation. The columns of this collection is specified and controlled.
