400 A Diaphragm Meters


Actaris’s 400A meter is the most compact and lightweight 400-class meter on the market today. Maintaining the use of a wearless orbital valve, single convolution diaphragms, and lubrication-free bearings, the 400A delivers maximum initial and sustained accuracy. Actaris “A” Series meters give you the physical size you need, without compromising our tradition for highly accurate meters that are a good value. This customer-driven design makes for easier handling in the shop and the field. The “A” Series retrofits to any meter set within its capacity range, eliminating the need for “installation specific” meter inventory.
