Flow through a large penstock such as used at a hydroelectric power plant can be measured by averaging the flow velocity over the entire area.
Water flow sensor symbol.
Flow sensors symbols for use in electrical pneumatic and hydraulic schematic diagrams.
The transducers sensors and electrical and electronic detectors are elements activated by the energy delivered by a system and that in turn deliver another type of energy to another different system the transformed energy may be of physical chemical or biological origin.
Reducer is the component in a pipeline that reduces the pipe size from a larger to a smaller bore inner diameter.
Process flow diagram symbols piping and connection shapes flange is a projecting flat rim collar or rib on an object serving for strengthening or attachment or on a wheel for maintaining position on a rail.
Propeller type current meters similar to the purely mechanical ekman current meter but now with electronic data acquisition can be traversed over the area of the penstock and velocities averaged to calculate total flow.
Pre drawn flow meter symbols represent analog output flow sensor cyclonic flow meter flow element flow totalizer flow tube temperature smart magnetic etc.
Symbols of electronic sensors transducers detectors.
