The OMEGA™ FPB100 Series flow sensor is the next generation in fluid measurement technology.
This new sensor is an improvement on what is already an industry standard. It has the added
functionality of various output options including flow switch, multi-functional pulse divider or
4 to 20 mA. Additionally, it offers low flow, low power and high resolution and can be configured
onsite directly through the built-in user interface. Installation is simple because the OMEGA FPB100
Series utilizes the same fittings as the popular OMEGA FP5000 and FP8500 Series paddlewheel
sensors and fits into pipe sizes ranging from DN15 to DN200 (0.5 to 8"). Available in polypropylene
and PVDF, it is ideal for a variety of applications including chemical processing, water and wastewater
monitoring and scrubber control.
