Design, Features & Advantages
- Interchangeable flow tube assemblies and valves allow configuration changes without
removal from process system.
- Rib-guided, compression sealed flow tubes for
maximum float stability.
- Ceramic scales fired on flow tubes against a contrasting
background provide high visibility and durability.
- Standard or high-resolution metering valves available
on inlet or outlet (see page 8 for valve details).
- Ten-to-one rangeability. tubes
