The FTB2000 Series hall-effect
turbine flow rate sensors are ideal
for OEM applications involving
low-flow liquid monitoring. The low
cost, coupled with ¹⁄₂% repeatability,
makes it suitable for replacing
dispensing timer systems. Unlike
traditional timing systems, turbine
technology is not influenced by
changes in system pressure
caused by aging filters. The
sensor’s standard power and output
specifications make it easy to
retrofit to existing controllers.
