Flow Meter for Lowest Flow Rates

In many applications within the process, food and life sciences industries, the smallest amounts of a substance must be measured and added with a high degree of accuracy – whether in piping or in chemical reactors. Flavoring for foodstuffs, active ingredients for pharmaceuticals or corrosion-inhibiting substances in oil production are just a few examples. The newly developed Promass A from Endress+Hauser measures such substances drop-for-drop with a precision unmatched worldwide. Promass A guarantees maximum robustness and precisely measured values with unparalleled repeatability. All of this thanks to the innovative sensor concept, which sets new standards in Coriolis measurement technology. Promass A is light and compact – with no losses in performance or robustness. The measuring device is therefore ideally suited for space-saving installation, for example in modular process facilities and skids. 

Maximum precision thanks to the innovative sensor concept

The Promass A sensor system is mounted on a base plate that acts as a “shock absorber,” effectively shielding the Coriolis measuring system from external pipe vibrations and pipe forces. Other contributing factors are the much higher oscillation frequency of the measuring tube and its completely balanced oscillation behavior. At a maximum measured error of ±0.1%, measurements down to 8 g/min are possible, or – if the error is permitted to be max. ±1% – even a quantity of less than 1 g/min.

The device design – robust and industry-optimized

Due to the high corrosion resistance (stainless steel, Alloy C22; NACE MR0175/MR0103), Promass A is ideally suitable for process applications, and especially for offshore and onshore areas with aggressive, salty air. Other preferred applications are found in the food and life sciences industries with hygienic or sterile environments. This is ensured by various certificates and approvals (3-A, FDA, EC 1935/2004; FDA, USP Class VI, TSE/BSE) as well as stainless steel in pharmaceutical quality.
