Coriolis mass flowmeter is based on the Coriolis effect that offers mass flow measurements for both liquid and gases that do not require treatment process measurement compensations. This flowmeter use Coriolis deflection to measure mass flow rate. Coriolis flowmeters can measure flow through the tube in either the forward or reverse directions. In most designs, the tube is anchored at two points and vibrated between these anchors. It is calibrated on water, because the constants are valid for all other liquids. They utilize a curved shape pipe or sensor tube that is subjected to carefully controlled electromagnetic vibrations at its natural frequency while fluid is moving through it. They are also constructed of stainless steel providing a high resistance to corrosion. Coriolis flow meters are suitable for conventional as well as contaminated and non-Newtonian fluids.
Cork polishing belts are durable cloth backed belts that has a cork and abrasive resin surface. It is made of cork and pumice compound bonded to a fabric-backed belt. It is used in wet condition.
Corks are a material used for bottle stoppers. Corks are made from the bark of cork oak trees used to close amphoras, barrels and glass bottles. Cork's elasticity combined with its near-impermeability makes it suitable as a material for bottle stoppers. Cork is also used in rocket technology due to its fire resistance. It can also be used as bricks for the outer wall of a house. It also has low heat conductivity and is used as an insulating material.
