Common
The flow computer of the GDR 1501 series are used to calculate the current gas quantity. The actual amount of gas
can be displayed in cubic meters or liters on an hourly or minute basis. The total quantity counter can be output in
cubic meters or liters. The counter can display up to 100 million cubic meters. The resolution is 0.1 litres.
The devices process an input signal regarding the gas flow. For connection three different types of inputs are
available. The gas flow meters GD 300 / GD 500 can be connected directly to the platinum wire sensor in the NON-
ATEX area. In the ATEX area, the pulse input is connected via the HB 300 Ex. An input for open collector and reed
relays is integrated to connect third-party products.
The current output gives the current flow rate per hour or minute and the solid state relay passes the defined
pulses to a superior PLC system.
With the
ECO
and
PRO
version the normalized flow per hour or minute can be calculated and transferred with the
current output. The standardization can be calculated according to the standards DIN 1343, DIN 6358, DIN ISO
2533, DIN 102 / ISO 1-1975.
The required values of pressure and temperature are defined in the
ECO
version with fixed values.
The
PRO
version provides two additional current inputs for a pressure and temperature sensor.
All parameter settings / configuration can be set using the touch keypad.

Technical data
The device series GDR 1501 is based on the modular principle. This means that the inputs and outputs as well as
software options can be optimally adapted to the individual requirements of the system. The section gives you an
overview of the available variants and options.
