ERWEKA GTL
The ERWEKA GTL is the basic ERWEKA unit
for testing the flow characteristics of powders
and granulates. It is equipped with an ex-
changeable stainless steel hopper (200 ml) with
exchangeable outlet nozzle (3 sizes of nozzles
standard: 10.0, 15.0 and 25.0 mm; 3 different
sizes optional). The pre-weighed sample is
filled into the hopper and a light sensor located
under the outlet of the hopper measures the
flow time.
When determination of flow time of the sample
volume is requested, two additional stainless
steel hoppers with different volumes are avail-
able as an option.
The unit is controlled via the numeric mem-
brane keypad, results are shown by the illumi-
nated 4-line LC display.

ERWEKA GT
The ERWEKA GT has been designed to offer
either measurement of flow time according to
specified amount (weight or volume) or amount
(weight) according to specified time. It is
equipped with an exchangeable stainless steel
hopper (480 ml) and exchangeable out-let noz-
zle (3 sizes of nozzles standard: 10.0, 15.0 and
25.0 mm; 3 different sizes optional) as well as a
balance located under the outlet of the hopper.
The product data is entered via the alpha-
numeric keypad, results are shown on the illu-
minated 320 digit full-graphic LC display and
can be printed out using the standard parallel
printer interface or transferred to a PC via the
standard RS 232 interface.
