FL-O5, $670, shown smaller than actual size.
The FL-O Series of industrial 
flowmeters is designed expressly for 
flowrate monitoring of petroleumbased oils and coolant fluids. These 
simple, rugged meters are designed 
for industrial use with all 300 Series 
SS and PTFE wetted parts and an 
aluminum housing. There are no 
fragile glass tubes, and the flowrate 
can easily be read even with 
opaque fluids. The built-in signal 
switch can be used as an alarm to 
report high or low fluid rates. FL-O 
flow monitors are also capable of 
withstanding the extremes of 
industrial use, with 200 psig and 
-18 to 93°C (0 to 200°F) 
environmental ratings.
