Rosemount Inc. is a subsidiary of Emerson Electric Company.Its headquarters is located in Shakopee, Minnesota, where they manufacture measurement instrumentation such as pressure, temperature, level, DP flow, and wireless, as well as analytical and detection instrumentation for gas analysis, liquid analysis, combustion measurement and flame and gas detection.
A simplified version of the definition is: The k v factor of a valve indicates "The water flow in m 3 /h, at a pressure drop across the valve of 1 kgf/cm 2 when the valve is completely open. The complete definition also says that the flow medium must have a density of 1000 kg/m 3 and a kinematic viscosity of 10 −6 m 2 /s, e.g. water. [clarify]
The DP-cell will indicate the relative difference between the pressure of the vessel (container) and the atmospheric pressure. This signal is often wired to an indicator that reads out locally, or remotely in a control room, and/or as a control (or feedback) signal to a valve, pump, or other control element to maintain a set pressure, or limit ...
These detect levels of very fine powders (bulk density: 0.02–0.2 g/cm 3), fine powders (bulk density: 0.2–0.5 g/cm 3), and granular solids (bulk density: 0.5 g/cm 3 or greater). With proper selection of vibration frequency and suitable sensitivity adjustments, they can also sense the level of highly fluidized powders and electrostatic ...

As the inertia of the tube depend on its contents, knowledge of the fluid density is needed for the calculation of an accurate mass flow rate. If the density changes too often for manual calibration to be sufficient, the Coriolis flow meter can be adapted to measure the density as well.
If the power quantity P is proportional to F 2, and if the reference value of the power quantity, P 0, is in the same proportion to F 0 2, the levels L F and L P are equal. The neper, bel, and decibel (one tenth of a bel) are units of level that are often applied to such quantities as power, intensity, or gain. [6] The neper, bel, and decibel ...
