EFM Test Bench is the industry’s best tool for testing electronic flow measurement computers. It is designed for systematic, automated, end-to-end testing of every aspect of flow measurement performance, including analog inputs, calibrations, internal calculations, historical record storage, and information retrieval by a measurement host.
Using EFM Test Bench, you can easily:
EFM Test Bench accurately calculates the correct flow rate and accumulated volume using the latest AGA-10 calculations, and compares it's calculations with the flow computer being tested.
FM Test Bench is of particular interest to:
Any combination of line conditions and gas conditions that you can imagine, can be used as a test signal. In this example, the static pressure and line temperature have been ramped, and step changes have been applied to the differential pressure for the first part of every hour. Thereafter, the values are randomly changed every ten seconds.
Low flow cutoff and static pressure compensation can be tested, as can k-factor and Reynolds number tables.
The EFM Test Bench generates comprehensive reports as Excel spreadsheets. Below are a few examples of the reports.
