A flow meter is a helpful tool used to measure the amount of a substance that passes through them. Flow measurement tools calculate either flow amount over a given time or total amount. Industrial flow meters measure the flow of water, lubrication, electrical current, air or gases as well as many other substances.

A flow measurement tool consists of the primary device, a transducer and a transmitter. The transducer monitors the passage of the target substance through a pipe or line, and the transmitter sends a signal carrying the flow information. The information ensures that the flow is at the appropriate level, gives usage for billing, and provides alerts on flow problems.

Flow meters are an essential piece of equipment for any business that need to regulate the flow of a substance. New technologies have made them adaptable to many uses. When selecting a flow meter supplier, consider the following:

1. What type of professional measurement is needed for your flow meter use?

2. What type of technology best suits your needs?

3. What flow meter distributors specialize in the type of meter you are looking for?

Decide what features you want in a flow meter

Do your research on flow measurement tools, including the features recommended for your business needs. One size does not fit all needs so review the features carefully.

I recommend: Omega Engineering provides general information on flow meters, including a discussion of features and types. Universal Flow Monitors, Inc. offers information on a range of flow meter features and types, including a glossary of terms, to help customers choose the right flow measurement tool.

Purchase the flow meter that best serves your needs

Flow measurement tools measure different things--liquids, gases, or slurries (solids suspended in liquid)--and work in different ways. Determine whether you want a flow meter that measures mass, volume or determines the flow inferentially by calculating other parameters.

I recommend: Sierra Instruments has product selection tools that allow you to enter your information and view recommended flow meters. Yamatake America has more than 100,000 instruments in use and offers a "try before you buy" program to make sure you select the right flow meter for your business.

Locate flow meter suppliers

Find a flow meter distributor that carries the instruments you need. This company will carry flow meters for your specifications and provide service for it's products.

I recommend: Industrial Quick Search provides a directory of flow meter manufacturers and distributors. You can find similar information at Flow Meter Directory, as well as a tutorial on types of flow meters and associated products.
