that prevents the unit from depressurizing unexpectedly.
The gauge model can be retrofitted with
the pump as an accessory.

Hydraulic and Gauge
Deadweight Tester
PRODUCT DESCRIPTION
The HydraLite Hydraulic Deadweight Tester is a primary standard
that features a re-entrant type measuring piston and cylinder assembly that helps maintain accuracy as the test pressure increases.
The HL Series tester is designed for rapid interchanging between
high and low pistons and is NIST traceable and accurate to ±0.05%
using non-magnetic die-cast alloy or aluminum weights calibrated
to international standard gravity at 9.80665 m/s2. A compact screw
pump with ratchet handle is easy-to-use. The unit is also available
as a deadweight gauge for accurate measurements and use as a
comparison standard.
Low center of gravity
he HL tester is an easy-to-use and portable primary standard capable
of offering laboratory accuracy in the field. The unit is designed to be
self-contained with all necessary components stored under the cover.
A screwpump pressure source on the tester model offers a convenient
method to raise and lower pressure for rapid testing.
Overhung Weight Carrier
Reduces side thrust and friction on the
measuring piston and cylinder assembly, thus improving measurement accuracy
Positive Over-pressure Protection
Prevents Piston Damage
NIST Traceable
All units are supplied with certifications
that are traceable to NIST.

FEATURES
Two accuracies available
These instruments are available in ±0.100% and ±0.050%
of reading. The accuracy stated is the overall accuracy of
the tester. The accuracy takes into account linearity, hysteresis, and repeatability. It would also account for intrinsic
corrections. Site corrections are the user’s responsibility
and the unit will not perform as specified without them.The
testers are manufactured to International Standard Gravity
and a local gravity site correction is easily performed with
a ratio correction to the output.
Easy Leveling
AMETEK floating ball testers incorporate a bulls-eye level
for reference when preparing the unit for use. The tester
also employs a 3-leg leveling system which is more con-
venient and is superior to a 4-leg system.
Re-entrant piston / cylinders
The HL deadweight
employs a re-entrant
type piston/cylinder
assembly. This design
applies test fluid to
the outside and inside
of the cylinder. Unlike
a simple piston/cylinder, this configuration
reduces clearance
between the piston
and cylinder as pressure increases. This
reduces the rate of
fluid leakage and
increases float time, offers the technician more time for
testing, and reduces the amount of pumping necessary to
sustain the fluid loss.
Pressure media
Because the HL is manufactured using brass and aluminum components, AAA Tester Oil is the recommended
and supplied pressure media. Other fluids compatible with
stainless steel, brass, aluminum, and Buna may be used;
however, consideration should be given to the cleanliness
of the fluid. AAA Tester Oil is triple-filtered to remove suspended solids that can harm the piston/cylinder assembly.
Overhung weight carriers
Another feature of HL deadweight tester is the way that
the weights are positioned on the carrier - an overhung
weight carrier design. This design employs a tube carrier
that is positioned over the column and onto the piston
driver, which lowers the center of gravity of the weights
reducing side thrust and friction. This design lengthens
the life of the piston and cylinder assembly thus improving
measurement accuracy.
Over-pressure protection
The measuring pistion assembly features positive overpressure protection restrivting vertical movement of the
measuring piston by a piston cap. This positive stop will
prevent the piston from damage due to accidental removal
of the weights when pressurized.
Worldwide engineering units
The HL deadweight tester and HLG gauge can be manufactured in four different engineering units: psi, bar, kg/
cm2, and kPa. All of the different engineering units are
available in any of the configurations.
HydraLite HLG Gauge
The AMETEK HydraLite HLG Gauge is a precision, portable instrument used to accurately measure pressure in
field conditions. The HydraLite HLG gauge may be used
as a primary standard instrument where a high accuracy reference measurement is needed. Simply connect
the gauge to the process and add weights until there
is a proper float. Standard accuracy is ±0.1% of indicated pressure traceable to the U.S. National Institute of
Standards and Technology (NIST). The instrument may
also be specified with +0.05% accuracy.
If you initially need a gauge and later find that you need a
full tester, an accessory kit is available to incorporate the
screwpump into the gauge.
