Back-up Rings

(120 companies)
Back-up rings or anti-extrusion rings are washer-like devices used to prevent seals from extruding through gaps while under pressure. Seals are installed in the downstream side of the gland.

Gas Flow Meters

(427 companies)
Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage.

Air Flow Sensors

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

Turbidity Instruments

...flowing at between 0.1 and 1 liters per minute. Because on-line devices are subject to continuous flow and sampling, their detectors must be cleaned frequently to prevent fouling and eventual failure. Three designs: benchtop, portable, and on-line...
Meter provers and flow proving components provide a known traceable volume to simulate actual operating conditions to test and verify the performance of flow meters and transfer meters.

...element to prevent errors due to stray capacitance. The capacitance of two parallel plates is given by the following equation: C= uA/d. Where: u = dielectric constant of the material between the platesA = area of the platesd = spacing between the plates...

Test Tubes

(105 companies)
Test tubes are handheld tubes are used for mixing or heating chemicals in a laboratory. They are open at the top and rounded at the bottom, and usually made of glass or plastic materials

Flow Switches

(366 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.
Pressure test connectors are mechanical assemblies for leak testing and filling fluids. They comprise a fitting connected to a fluid source, a flow control valve, and a quick connecting fitting to make the connection with the destination assembly.

Test Sieves

(79 companies)
Test sieves are stainless steel or brass round frames with extremely accurate openings. Wire cloth is usually of stainless steel or brass with nonstandard wire diameters.
Electronics test fixtures are used to test contact points on circuit boards during manual or automated testing.

Flow Transmitters

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