A flow meter (flowmeter) or flow sensor is an instrument used in almost all mechanical, electrical and instrumentation processes to measure the flow rate of a liquid or gas. A rotameter (commonly called a variable area flow meter) is one type of flow meter.

EMI gaskets are mechanical seals employed to cover gaps in between electronic components so as to prevent electromagnetic interference effectuated by electronic circuits. These gaskets are positioned in between the mating surface and the shield housing of the electronic devices. Conductive foam, fabric over foam, mixed media silicone, elastomer, metal, conductive yarn and mesh are some common types of gaskets of this class. Such gaskets are common in defense electronics, interconnections, medical electronics, aerospace, automotive electronics and in sensitive equipment utilized in industries.

A regenerative catalytic oxidizer (or RCO) is a variant of the regenerative thermal oxidizer where the ceramic media (used to recover heat energy from the oxidization process) is coated with a catalyst that aids in the oxidation of the exhaust gases at lower temperatures. This results in an increased reduction in the operating costs as compared to conventional regenerative thermal oxidizers. The catalysts that are normally used are precious-metal catalysts, such as platinum or rhodium.

Right angle gear reducers are secondary worm gear reducers used to lower speed and increase torque of components. High speed input shaft and the low speed output shafts are positioned perpendicular to each other. Reducers of this type are generally variations or modifications of parallel and in-line shaft reducers. These reducers exhibit high levels of efficiency, and are used in glass-cutting equipment and printing presses. These types of speed reducers are widely used in industries such as food and beverage processing, automotive, recreational, oil and gas and aerospace.

Rubber bonded to plastic is a product obtained by adhering plastic substrates to rubber. This cohesion between the conductive elastomers and the substrate is realized by chemical and/or mechanical bonds. In the case of chemical bonding, the conductive elastomer is subjected to vulcanization, and the rubber is attached directly to the plastic substrate with the assistance of bonding agents during the process of molding. The bonding agents are composed of polymer or solvent solutions. The thickness assumed by the bonding layer is based on the nature of rubber formulation. Areas of application include commercial, medical and industrial fields.

A recirculating chiller is used for the extraction of heat from a liquid - either water or any industrial process fluid. The recirculating chiller consists of an evaporator, a condenser, compressor, and thermostatic expansion valve. The chiller works by cooling a refrigerant, which is then used to extract heat from another fluid. Recirculating chillers are used in a number of industries for various cooling applications, including cooling MRI machines and lasers.

A rotary dashpot (also known as a rotary damper), is a mechanical device that uses viscous friction to resist motion. The resisting force is equivalent to the velocity acting in the opposite direction, resulting in decelerated motion and absorbing energy. Rotary dashpots are commonly applied with springs that are used to resist displacement. Some of the common applications of rotary dashpots include mechanical delays, shock absorption, speed control, and slipping drives.

Robotic grippers, also termed as end-effectors or end of arm tooling, are, in actuality, the physical interface through which robotic actions are realized. The gripping elements are either angular or fingers that are pivotal about base points or jaws that glide in parallel or in the same plane like chuck jaws or clamps. These grippers respond to hydraulic, pneumatic or electrical actuation. They are marketed in various configurations, and are engaged to lift and deliver objects of myriad sizes and shapes including bottles, cans, boxes and bags.
