About Volumetric Liquid Flow Switches

Volumetric liquid flow switches measure the flow or quantity of a moving fluid in terms of a unit of volume per time, such as liters per minute. These flow sensing devices have a switch output. Pipe size and pipe style are important specifications to consider when selecting volumetric liquid flow switches. There are three main parameters: pipe diameter, mounting style, and end fittings. The pipe diameter is specified in English units such as inches (in) or metric units such as centimeters (cm). There are three choices for mounting type or style: in-line, insertion, and non-invasive. End fittings for volumetric liquid flow switches include clamps as well as compression, flanged, plain end, threaded, and tube end fittings. Socket welds or unions are also used.

Products & Services Related to Volumetric Liquid Flow Switches

Flow Meters

Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.

Flow Transmitters

Flow transmitters provide electrical outputs that are proportional to flow inputs. They use flow meters to measure the flow of liquids and gases.

Paddlewheel Flow Meters

Paddlewheel flow meters have a paddle wheel that is perpendicular to the flow path. The rotor axis is positioned to limit contact between the paddles and the flowing media.

Positive Displacement Flow Meters

Positive displacement flow meters measure the volume or flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes. These devices consist of a chamber that obstructs the media flow and a rotating or reciprocating mechanism that allows the passage of fixed-volume amounts.

Rotameters

Rotameters are typically tapered glass tubes positioned vertically in the fluid flow. A float within the tube rides upward in relation to the amount of flow.

Turbine Flow Meters

Turbine flow meters measure the rate of flow in a pipe or process line via a rotor that spins as the media passes through its blades.

Vortex Flow Meters

Vortex flow meters are flow sensors that detect the frequency of vortices shed by a bluff body placed in a flow stream. The frequency of the vortices is proportional to the flow velocity.
