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.
Pre drawn flow meter symbols represent analog output flow sensor cyclonic flow meter flow element flow totalizer flow tube temperature smart magnetic etc.
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.
Weir meter symbol isa symbology the symbology for the identification of the measurement and control instrumentation on the flow and process diagrams and on the p id piping instrument diagram commonly called p i piping instrumentation is generally compliant with the standard isa instrumentation society of automation identified as s 5.
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.
Reducer is the component in a pipeline that reduces the pipe size from a larger to a smaller bore inner diameter.
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.
