Mounting Type
|

|
| |
Your choices are...
|
|
|
| |
In-line
|
|
In-line flow meters are installed directly in the process line. They have a variety of end-fittings, including flanges, threads, and compression fittings. Typically, in-line flow meters require a straight run of pipe for installation.
|
| |
Insertion Type
|
|
Devices are inserted perpendicular to flow path. They usually require a threaded hole in the process pipe or another means of access.
|
| |
Non-Invasive
|
|
Non-invasive flow meters do not require mounting directly in the process flow and can be used in closed piping systems. Ultrasonic flow meters such as Doppler devices may use this type of mounting to read the flow through the pipe.

Clamp
|
|
Devices are inserted parallel to the flow path and clamped between two existing process pipes. External clamp-on flow meters are non-invasive. They do not require mounting directly in the process flow and can be used in closed piping systems. Ultrasonic, or Doppler, flow meters may use this type of mounting to read the flow through the pipe.
|
| |
Compression
|
|
Compression fittings tighten down a sleeve or ferrule over a joint to prevent leakage.
|
| |
Flanged
|
|
Devices are inserted parallel to the flow path, usually between two pieces of existing, flanged process pipes. Circular or square flanges are used to connect the fitting, typically via bolting or welding.
|
| |
Plain End
|
|
Devices have a plain, straight-pipe end that can be inserted into the bell end of the connecting pipe.
|
| |
Socket Weld / Union
|
|
The end fitting is designed for welding or soldering and can be a weld neck.
|
| |
Threaded
|
|
Devices are inserted parallel to the flow path and threaded into two existing process pipes. National pipe thread (NPT) is the most common thread type.
|
| |
Tube End / Hose Nipple
|
|
Tube-end or hose-nipple is a common description for a short piece of pipe, usually with male threaded ends.
|
| |
VCO® / VCR®
|
|
VCO® and VCR® connections are proprietary, threaded fittings for vacuum applications that use the Swagelok design. VCO® fittings have an O-ring face seal. VCR® fittings have a metal gasket face seal. VCO and VCR are registered trademarks of Cajon Company. Swagelok is a registered trademark of Swagelok Co.

A meter's performance can be determined by its turndown ratio. Turndown ratio is the effective dynamic or operating range of the flow meter. For example, if a 500 SCCM flow rate device has a turndown ratio of 50:1; it will operate effectively and resolve flow down to 10 SCCM. If the same device has a turndown of 100:1, then it will resolve effectively to 5 SCCM.
