Flex® Process Indicators
1/8 DIN Analog Input Panel Meters

Sunlight readable, .56” red 5-digit display
Veeder-Rroot Flex series, 1/8 DIN panel mount process indicators


  • Process, voltage, current, temperature, and strain gage inputs
  • 5-digit 0.56" red sunlight readable display
  • Variable intensity display
  • 16 point scaling for non-linear processes
  • Programmable function keys/user inputs
  • 9 digit totalizer (integrator) with batching
  • Optional custom units overlay w/backlight
  • Four setpoint alarm outputs (w/option card)


FLEX® Analog Panel Meters offer features and performance capabilities to suit a wide range of industrial applications. Available in five different models to handle various analog inputs, including DC Voltage/Current, AC Voltage/Current, Process, Temperature, and Strain Gage Inputs. The optional plug-in output cards allow the opportunity to configure the meter for present applications, while providing easy upgrades for future needs. The meters have been specifically designed for harsh industrial environments and employ a bright 0.56" LED display making it ideal for viewing in bright light applications. With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects to CE requirements, the meter provides a tough yet reliable application solution.

In addition, plug-in modules allow PV retransmission or transmitter power supply and up to 5 alarm relays (latching or non-latching). The Flex® indicator is affordable, full featured, easy to use and compact with performance features that work for you to make temperature and process display simple.

The Flex® digital indicator like its predecessor, the S428, remains an easy to use low cost solution for process display applications including temperature, pressure and force – providing excellent visibility and high accuracy all within an affordable and ultra compact housing
