## Description

Stack Testers Flow Friend is part of a suite of apps developed by the Engineers of CES Environmental Instruments, one of the UKs leading environmental Test Houses and incorporates some of their on-site calculations in an easy to use app.

When working on the stack and you need to quickly calculate a velocity or volume flow, the answer can be at your fingertips.  By inputting the essential parameters of the stack size and gas conditions, the velocity and volume flow can be determined without the need to manually calculate the value or start up a laptop.  The app is an essential tool for the professional Environmental engineer. 

The app is a useful aid to the C & I engineer calculating the Differential Pressure cell mA output used for data logging.

The contents of the CES Environmental Instruments popular Engineers Note Book is preloaded within the app.
