Flow computers, totalizers, and rate indicators integrate the functions of flow and temperature measurement, computation, data acquisition, input / output (I/O) standardization, and closed loop control. They require external sensor inputs and may be used as local rate indicators.
Polyamides comprise a family of thermoplastic polymers made of amides joined by peptide bonds. Nylon is a generic name given to polyamide materials. Polyamides are commonly used in textiles, automotive components, carpet, and sportswear due to their extreme durability and strength.
Thermostats and thermal switches are electro-mechanical on/off switches that are activated by temperature changes. They are typically used to control heating and cooling systems.

Level Switches

(584 companies)
Level switches is a generic search term 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.

Flow Meters

(1,655 companies)
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.

Control Valves

(1,613 companies)
Control valves or proportional valves are power-operated devices used to modify fluid flow or pressure rate in a process system.

Flow Switches

(344 companies)
Flow switches are devices that monitor flow and send a trip signal to other devices, like a pump, for protection. These switches can be used for the measurement of gases, liquids, and steam.

Flow Transmitters

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

Air Flow Sensors

(260 companies)
Air velocity flow sensors measure air velocity or volume flow using insertion probes or capture hoods.

Flow Controllers

(417 companies)
Flow controllers monitor and maintain flow-rate variables, typically in process applications.

Gas Flow Meters

(418 companies)
Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage.
Flow orifices and flow restrictors contain precision-machined holes and filters or screens to restrict flow and reduce pressure. They are available as stand-alone devices and in kits, assemblies, restrictors, and restrictor valves.

Mass Flow Switches

(35 companies)
Mass liquid flow switches and mass gas flow switches are devices used for measuring the flow or quantity of a moving liquid or gas in terms of a unit of mass per unit time, such as pounds per minute. These devices may be sensors with electrical output or may be stand-alone instruments with local displays and controls.
