J-TEC
flow
meters operate on the principle of vortex shedding.
A small strut inside the
flow
tube creates a Karman vortex street
and the vortex formation is sensed by means of an ultrasonic
beam directed across the tube. The
flow
meter electronics uses
the vortex frequency to determine the
flow
rate.
The J-TEC HBM453 is a two piece design, consisting of a
handheld enclosure with a display, battery power compartment,
interface cable and a separate
flow
measurement body.
J-TEC
flow
meters have a 12-month warranty period.
