1. Outline
FM01 series vortex flow meter measures flow velocity (vortex) of liquid (water) running through the tube
hole, detects vortex frequency proportional to the velocity, and outputs 4 to 20mA through the processing
circuit.
It is a small plastic vortex flow meter, and the
velocity and flow rate in a wide range of use, the
output signal is 0.5 to 4L/min for FM0101, 2 to
16L/min for FM0102, 4 to 40L/min for FM0103, 10
to 150L/min for FM0105, and 25 to 250L/min for
FM0107.
This instrument has no movable portion, pressure
loss is small, output signal is proportional to the
volume flow rate, and it is superior in linearity and
reproducibility.
For the main body, PPS resin (polyphenylene
sulfide) is used to secure mechanical strength and
high reliability. It has a simple structure with less
liquid accumulation, thus realizing maintenance-free
without
necessity
of
periodical
checking/maintenance.
