Portable Mass Flow Meter Battery Powered

Some installations require a portable solution for measuring flow or to verify an instruments flow rate. Powered by a standard 9V battery, the Apex Battery Powered Mass Flow Meter is an economical choice.

Typical applications include:

- Verifying flow of other mass flow controllers
- Searching for leaks in the system using either flow or pressure
- Performing quality control checks on a system
- Field verification of flow applications


Companies spend time and money to verify that installed equipment in the field is working properly. In most cases, the equipment has to be removed from service and sent to a metrology lab or an in house testing center for verification. Removal of installed equipment takes time and in some cases requires that the process be shut down for removal and in some cases stay down until the device under test is returned from testing.
