The 1-channel flow computer/ volume corrector GDR 1540 is used to calculate the current gas volume of gas flow meters with a Namur output.
On an hourly or minutely basis, the current gas quantity can be displayed in cubic meters or liters. The total counter reading can be displayed in cubic meters or liters. The counter can have 9 digits up to 999 million cubic meters. The resolution is 0.1 liters.
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.
Inputs: Gas flow meter
1. Namur input (2-fold)
Inputs: Pressure and temperature
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 atmospheric pressure.
Output and bus system
The 0(4) – 20 mA current output provides the current flow rate in the form of operating or standard cubic meters. Via 2 solid state relays, flow rates, device status, error messages or limit values can be transmitted to higher-level systems for further processing.
The Modbus RTU and Modbus TCP bus systems are available as an option for data transmission.
All parameter settings/configurations can be carried out using the keys and the display or with a web browser via the integrated WLAN hotspot.
