A device decreasing noise in a HVAC system.

A physical object that is intended to keep other physical objects at a predefined distance and hence having a spacer function.

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 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.

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

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 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.

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.

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

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

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

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.
