J-TEC HBM453 Operator's Manual

HBM453 DISPLAY & BLOW-BY METER SYSTEM
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.
