An 'equipment class' that is a class of devices engaged in meteorological observations
A device that is capable of three-phase metering of liquid, oil and gas.
An operated valve that is opened and closed with a motor.
An analyser giving as output a signal that represents more than one physical properties of the analysed substance.
A flow meter for the metering a mixture of two or more fluid phases.
A needle valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.
A level transmitter that is producing a standardized electrical output signal based on the input signal from a nucleonic level detector.
A mist detector that is intended to detect oil mist.
An element designed to measure an oxidation reduction potential (ORP).
An analysing instrument intended to measure, indicate and/or produce a signal which represents the measured alkalinity / acidity in a fluid or matter.
An element designed to measure pH (potential of Hydrogen).
A detector that is intended to detect a pig inside the pipeline or pig receiver.
A lift check valve that has a free gravity or spring loaded piston type closure member.
A fluid sensor producing a differential pressure by means of two straigth tubes mounted in line with the direction of the fluid movement. One tube is open-ended and measures the stagnation pressure of the fluid. The other tube is closed in front but has openings along the tube to measure the static pressure of the fluid.
A differential pressure flow meter utilizing a pitot tube (a probe with an open tip) that is inserted into the flow field.
A control valve that is also a plug valve and an actuated valve.
An actuator that is intended to be operated by pneumatic power.
A mechanical controller that is using pneumatic components to execute its function.
A pilot switch the actuating system of which is operated by a moving part of a machine, when this part reaches a predetermined position.
A transmitter that is producing a standardized output signal dependent of a received input signal from a position detector.
Elements like impellers rotating by the pressure of the fluid in a closed conduit to measure the flow of a liquid.
A flow transmitter specially designed to convert the signal from a positive displacement flow meter into a standardized electrical output signal.
An analysing instrument intended to determine the pour point of a fluid, i.e. the lowest temperature at which an oil or other liquid will pour under given conditions.
A detecting element intended to sense pressure.
