Flow Computer GDR 1501

GDR1501

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.

DESCRIPTION

The devices process an input signal regarding the gas flow. For connection three different types of inputs are available.

  1. The gas flow meters GD 300 / GD 500 can be connected directly to the platinum wire sensor in the NON-ATEX area.

  2. In the ATEX area, the pulse input is connected via the HB 300 Ex.

  3. 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 versions the normalized flow per hour or minute can be calculated and transfered 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.
