Proline Promass A 100 Coriolis Flowmeter
Brand: Endress+HauserProline Promass A 100 Coriolis Flowmeter
Brand: Endress+Hauser

Promass A is known for its highly accurate measurement of small quantities of liquids and gases for high pressure and low pressure. Combined with the smallest transmitter housing available today it delivers full performance on the smallest footprint. Promass A 100 is the preferred choice for system integrators, skid builders and equipment manufacturers. Available with an ultra-compact stainless steel hygienic housing it can be placed even into the most compact rigs.
