Level gauges are industrial meters used to determined the level of a liquid in a fixed storage or process tank

Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point

Level switches, all types, is a generic search form for devices that are used to detect liquid or powder levels, or interfaces between liquids. These level measurements are indicated via an electrical switching action

Liquid level sensors are used to detect liquid levels or interfaces between liquids such as oil and water or liquids and solids. 

Density and specific gravity instruments are meters used to determine density and specific gravity.

Storage tanks and process tanks are bulk containers of varying size and configuration

Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action

Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. For each measurement, they provide an electrical output that is proportional to the input level

Level controllers monitor, regulate, and control liquid or solid levels in a process

Analog pressure gauges are mechanical devices that include bellows, Bourdon tubes, capsule elements and diaphragm element gauges

Dry material (powders) level switches are used to measure levels of dry, solid materials via an electrical switching action

Digital pressure gauges use electronic components to convert applied pressure into usable signals. The gauge readout has a digital numerical display

Pressure gauges are used for a variety of industrial and application-specific pressure monitoring applications.  Uses include visual monitoring of air and gas pressure for compressors, vacuum equipment, process lines and specialty tank applications such as medical gas cylinders and fire extinguishers

Hydraulic reservoirs are storage tanks that hold liquids or gases used in fluid power applications. They are usually rectangular, cylindrical, T-shaped, or L-shaped and made of steel, stainless steel, aluminum, or plastic

Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure.
