DESIGN FEATURES
The Hastings NALL-Series Flowmeter is the
original model that has generated repeat
customers for over 50 years. It operates on
a unique thermal principle which permits
inherently linear response to flow. The flow
passage is constructed entirely of metal and
contains no O-rings. The transducer is also
separate from any electronic circuitry, mak-
ing it ideal for high temperature or other
adverse environmental applications. The
power supply features a bright digital dis-
play and is contained in either a cabinet or
panel mountable case.
All models feature high accuracy and excel-
lent repeatability.
