Case study
LCD for an Ultrasonic Flow Meter
Flow rate, totaliser and diagnostics on a clamp-on or inline meter used in plant rooms and pipelines.
The requirement
Flow meters are commissioned on site, often in a plant room or a pit. The engineer needs flow rate and totaliser; the maintenance team needs diagnostic states, pipe parameters and signal quality.
What we supplied
- Segment layout with a dominant flow field and a totaliser field
- Secondary indicators for units, pipe size and signal status
- Transflective structure: readable in daylight, backlit for pits and cabinets
- Wide temperature range for outdoor and unheated installations
Design note
Commissioning screens are used a few times in a meter’s life but decide whether the installer succeeds. We keep them readable rather than cramming them into the smallest field.
