Flow Computer GDR 1530

GDR1501

The actual gas quantity of the gas flow meter GD 300 (Ex) / GD 500 (Ex) is calculated by the 1-channel flow computer GDR 1530. 

On an hourly or minutely basis, the current gas quantity can be displayed in cubic meters or liters.

DESCRIPTION

The totalizer of the total quantity can be displayed either in cubic meters or in liters. The counter can have 9 digits up to 999 million cubic meters. The resolution is 0.1 liters.

2 different inputs are available for the input signal.

Gas flow meter GD 300 (Ex)/ GD 500 (Ex):

  1. Direct connection of the platinum wire sensor (NON-ATEX)
  2. Connection of the HB 300 Ex (ATEX area)

The current output 0(4) – 20 mA indicates the current flow in the form of operating or standard cubic meters.

Two limit values ​​are available for limit value monitoring.

Flow rate, device status or error messages can be passed on to superior PLC system via 2 semiconductor relays.

In addition to a pt100 input, the devices also have mA inputs for pressure and temperature sensors as well as an integrated barometric sensor for recording the atmospheric pressure.

Based on the operating volume determined by the connected gas flow meter and the measured values for pressure and temperature, the volume corrector calculates the standardized volume. The calculation of the standardization can be done according to the standards DIN 1343, DIN 6358, DIN ISO 2533 or DIN 102/ ISO 1-1975.

The Modbus RTU and Modbus TCP bus systems are available as an option for data transmission. 

Optional LAN interface for integration into the plant network

All parameter settings/configurations can be carried out using the keys and the display or with a web browser via the integrated WLAN hotspot.
