Applications
The Promass A series delivers exceptional precision in measuring minimal liquid and gas flows across both high and low-pressure environments. Featuring the most compact transmitter housing on the market, it provides complete functionality within minimal space requirements. The Promass A 100 model is particularly favored by system integrators, skid manufacturers, and equipment builders. Its ultra-compact stainless steel hygienic design allows installation in even the most space-constrained setups.
