The Dall tube is a shortened version of a Venturi meter, with a lower pressure drop than an orifice plate. As with these flowmeters the flow rate in a Dall tube is determined by measuring the pressure drop caused by restriction in the conduit. The pressure differential is typically measured using diaphragm pressure transducers with digital readout.
A DP cell is a device that measures the differential pressure between two inputs. [1]Example: To measure the pressure difference between a container (or vessel) and the surrounding atmosphere, you may connect 'Hi' port of the DP-cell to a fitting that enters the vessel, using suitable tubing.
The meter is "read" as a differential pressure head in centimeters or inches of water. The venturi meter and manometer is a common type of flow meter which can be used in many fluid applications to convert differential pressure heads into volumetric flow rate, linear fluid speed, or mass flow rate using Bernoulli's principle.
ISO 10628 Diagrams for the chemical and petrochemical industry specifies the classification, content, and representation of flow diagrams. It does not apply to electrical engineering diagrams. ISO 10628 consists of the following parts: Part 1: Specification of Diagrams (ISO 10628-1:2014) [1] Part 2: Graphical Symbols (ISO 10628-2:2012)
The flow meter utilizes a unique combination of a tapered metering cone in series with a piston. The position of the metal piston is sensed by the LVDT circuitry and is then translated into a flow rate. [citation needed] This non linear signal can be directly displayed or linearized with an electrical output.

Video of a Venturi meter used in a lab experiment Idealized flow in a Venturi tube The Venturi effect is the reduction in fluid pressure that results when a moving fluid speeds up as it flows from one section of a pipe to a smaller section.
Differential pressure is the difference in pressure between two points. Differential pressure sensors are used to measure many properties, such as pressure drops across oil filters or air filters, fluid levels (by comparing the pressure above and below the liquid) or flow rates (by measuring the change in pressure across a restriction ...
The meter is "read" as a differential pressure head in cm or inches of water and is equivalent to the difference in velocity head. The dynamic pressure, along with the static pressure and the pressure due to elevation, is used in Bernoulli's principle as an energy balance on a closed system .
