Equipment that requires this document type.

An analysing instrument that is intended to determine a physical property that is named thermal conductivity.

equipment class

An element which uses the principle of thermal conductivity to measure volume flow rate.

A velocity flow meter which uses the principle of thermal conductivity to measure volume flow rate.

equipment class

A pair of electrical conductors of dissimilar materials, joined at one end (the measuring or hot junction), which produces an electromotive force (e.m.f.) due to the Seebeck effect in a circuit formed by connecting the other ends of the dissimilar materials used (the reference or cold junction) to a device for measuring e.m.f. Def. acc. to IEC 902 1987.

equipment class

A physical object that is a pressure-tight receptacle adapted to receive a temperature sensing element, provided with external threads or other means for pressure-tight attachment to a vessel or pipe.

equipment class

A timepiece that measures a time interval and signals its end; a time-switch.

equipment class

A transformer that, by electromagnetic induction, transforms a system of alternating voltage and current into another system of voltage and current usually of different values and at the same frequency for the purpose of transmitting electrical power.

equipment class

A physical object that is an element that receives a process variable signal from a sensor and converts it into an output signal.

equipment class

A pilot switch intended to create a switch action at a pre-set value.

equipment class

A physical object that is intended to rotate within a fluid and to transform energy within a fluid into mechanical power.

equipment class

A velocity flow meter that uses a multi bladed rotor to measure fluid flow rate in units of volumetric flow through a closed conduit.

A transmitter specially designed to convert the signal in a turbine meter into a standardized output signal.

equipment class

A velocity flow meter that measures the velocity of a flow by measuring the time difference between an ultrasonic pulse sent in the flow direction and an ultrasound pulse sent opposite the flow direction.

A flow transmitter providing electrical outputs that are proportional to the flow inputs from an ultrasonic flow meter.

An element intended to determine a level based on ultrasonic sound waves.

A level transmitter that is using ultrasonic sound to continuously monitor the level of a liquid or particulate matter in a tank or vessel.

equipment class

A differential pressure flow meter that uses a v-cone as the restriction body in the flow stream.

equipment class

A fluid regulator that can be used to control (i.e. permit, obstruct, regulate or divert) a fluid stream.

An analyser intended to determine a vapor pressure.

equipment class

A pipe or tube that has a constriction with a relative long passage with a smooth coned entry and exit.

equipment class

A container intended for storage and/or processing of fluids.

equipment class

Is a mechanical screening device used to separate materials by particle size through the use of a mesh screen and a vibrating motion.

equipment class

A detecting element that is intended to sense mechanical vibration and in which the oscillating motion is transferred into a voltage or current signal.

equipment class

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

equipment class

A transmitter of which the output is proportional to a measured vibration.
