Air velocity flow sensors are used to measure the pace of airflow through a duct, pipe or other chamber. Air velocity flow sensor manufacturers create two types of sensors. One is a gauge inserted into the chamber through an open hole. The other is a flow hood, also known as a balometer, that measures the velocity of air at either its source or at an exhaust outlet. Both are designed to be durable in the force of air passing through.

There are many air velocity flow sensor distributors on the scene. Choosing one can be a daunting step in finding the right product for your purposes. Arming yourself with the following information can make the process flow smoothly:

1. Know the measurements and dimensions of the system you want to fit with a sensor.

2. Decide if temperature is a consideration in your testing. Many air velocity flow sensors have limited temperature ranges, and some models may not be equipped to take temperature readings at all.

3. Determine how often you will be gauging airflow. Some sensors are equipped with timers and alarms to make this easier, especially if the unit you are testing is not in an easily accessible area.

The best contacts and resources to help you get it done

Find air velocity flow sensor suppliers with comprehensive websites

If you are looking to buy an air velocity flow sensor online, several sellers have easy-to-use charts and interactive tools on their websites. These instruments are helpful when choosing the right sensor.

I recommend: The guides and tools at Sierra Instruments are informative and user-friendly. They also make it easy to get a quote and to speak with an expert in your local area. Fluid Components International, another air velocity flow sensor manufacturer, has a straightforward table breaking down their products into concise explanations of model, type and application.

Investigate the latest technology available from air velocity flow sensor providers

The fields of technology are forever changing, and it's a good idea to keep up-to-date on the latest improvements made to air flow sensors. There are many companies on the cutting edge of this ever-evolving industry.

I recommend: Flo Meters, a division of Pathfinder Instruments, is a leading manufacturer of some of the most technologically savvy units. Honeywell is a well-established air velocity flow sensor supplier with a selection of products and information.

Buy a refurbished air velocity flow sensor

If you're looking for a low-cost air velocity sensor, consider a refurbished model. In addition to paying a fraction of the cost, you are also being environmentally conscious by recycling and reusing.

I recommend: With an impressive variety, Don John's sells both new and used airflow sensors. Another good place to check is Lab X, which sells all sorts of second-hand scientific equipment and has an easily searchable database.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  Read through the handbook or design information on the equipment you are testing with the air velocity flow sensor. These documents contain valuable information that, in collaboration with the sensor, can help you reveal the correct or incorrect performance of your equipment.
