The FP-2541 and FP-3-1500
Series offer the added strength and
corrosion resistance of stainless
steel for applications requiring low
velocity measurement. Unique
internal circuitry eliminates the need
for magnets in the process fluid,
enabling lower flow measurement
while maintaining the advantages
of insertion-type sensor design.
The sensor’s unique rotor/bearing
design offers low flow measuring
capability with increased reliability.
