Flow meters are used to measure the rate of flow of liquids or gases, just like electric meters measure the amount of electricity consumed. However, unlike electric meters, which are either ...

Designers should always consider flow velocity through hose and tubing to optimize performance while avoiding excessive losses or pressure spikes. This aerospace high-pressure pump installation ...

A flow rate test is used to work out the melt flow rate (MFR) of a thermoplastic material. According to ASTM 1238, “Method A” test involves the collection of extrudate from the die over a set period ...

The two main MFI test standards are ASTM D1238 - “Standard Test Method for Melt Flow Rates of Thermoplastics by Extrusion Plastometer” and ISO1133 – “Determination of the Melt Mass-Flow Rate (MFR) and ...
