A gas mass flow meter is the tool you are looking for if you are trying to directly determine the amount of gas passing through a point at any given time. Before purchasing your gas mass flow meter make sure that you have a clear understanding of what you expect to gain from the product first. You can purchase heavy duty industrial flow meters with many features or you can purchase a simple flow meter for use in your home. Also keep in mind that if you want to measure a liquid such as water you will want to purchase a liquid mass flow meter.
Things to Consider Before Purchasing a Gas Mass Flow Meter
Not all gas mass flow meters allow you to remotely transmit the data acquired by your device. If this is a function that you will be requiring you will need to pick your meter accordingly. If you do select a gas mass flow meter that is capable of transmitting data remotely make sure its update frequency also corresponds with your expectations for the device.
Think about how easy your gas mass flow meter needs to be. The complexity of these devices varies greatly from one product to another. If you just need a simple flow meter make sure to purchase a stand alone device that does not require attachment to a computer for configuration.
If repeatability is your greatest concern when purchasing a gas mass flow meter, select a device that has a limited amount of moving parts. The fewer parts you having moving in the cavity of your gas mass flow meter will result in a more repeatable and consistent outcome.
If you know that the commodity you are trying to measure consists of large particles, you may be required to use a filter with your gas mass flow meter. Check individual product specifications for details.
One possible drawback to using a flow meter is the possibility of pressure drop. This is caused by the leaking of gas instead of the capturing of gas in the flow meter cavity. Also keep in mind that your meter will need to be calibrated to whatever type of gas you will be testing.
Consider the available power supply for your gas mass flow meter. Many devices offer optional battery packs if an electrical source is inconvenient or not feasible. As with any battery operated device, products with this option are going to provide the user with fewer details and features. |
