Anchor security seals are strong and suitable for a wide range of sealing applications. The one-piece seal consists of a hollow capsule and anchor type insert connected by a thread. Upon insertion, the legs or barbs become permanently retained behind the inner stops of the capsule, so the anchor cannot be withdrawn. These seals offer higher security and easier sealing procedure without the use of tools.

An anemometer is a meteorological instrument used to measure wind speed, temperature and humidity. It also calculates and displays dewpoint and wind chill factor. It is essential for monitoring the environment. It can be divided into two classes: one that measures the velocity of the wind, and another one that measures pressure of the wind.

An anemometer is a device for measuring the velocity or the pressure of the wind, and is one instrument used in a weather station. Anemometer can be divided into two classes: those that measure the velocity of the wind, and those that measure the pressure of the wind, but as there is a close connection between the pressure and the velocity and a suitable anemometer of either class can give information about both these quantities.

Annunciators are electrical signaling devices, used in hotels or offices to indicate the sources of calls on a switchboard. It is an indicator that announces which electrical circuit has been active (as on a telephone switchboard). It annunciates the status of industrial processes, security and fire alarms of buildings. It may come in any combination of visual indication and/or audio alarms. A visual indication may be provided by a graphic display panel lit with lamps or bulbs, a digital display like that of an LED or LCD, or a computer or video monitor. These annunciators also include mosaic graphic displays, and control graphic displays. Audio alarm annunciators include air horns, sirens, bells, buzzers, speakers (for a paging system or voice evacuation), whoop sounders or hooters.

Armored sight flow indicators are used to observe the flow of liquids in a piping system. A rigid steel housing surrounds the sight tube and provides additional strength and protection from mechanical impact. Threaded and flanged connections are available in a variety of sizes to match the diameter of the pipe being used. Wide ranges of housing materials are also available. Units can be made with any overall length if additional visibility is required. Wetted materials consist of glass and the connection end plates. Armored sight flow indicator is recommended for low-pressure vertical or horizontal applications. Maximum pressure allowable will vary with temperature and size.

Ash Level Detector provides solution to fly-ash measurement.

ASME Flow Nozzles provide accurate measurements. Their use is limited because they are not easily placed in a process plant. They are excellent for shop tests. The venturi meters and nozzles can handle about 60% more flow than orifice plates with varied pressure losses.
