A transducer which produces a signal with a defined relationship to the force applied to it.
A level gauge that use a float containing a magnet to transfer information about its position to a indicator rail with white and red flaps mounted on the outside of the tube.
A level transmitter which uses a floater and magnetic contacts to measure and transmit level.
A control switch that is operated by a person.
A switch which is operated by a person.
A valve that is regulated with hand power.
A mechanical controller that is intended to position a given item in accordance with a received input signal.
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.
