The 1-channel flow computer GDR 1540 is used to calculate the current gas volume of gas flow meters which can be connected via an open-collector/reed relay or Namur input.
On an hourly or minutely basis, the current gas quantity can be displayed in cubic meters or liters.
4-line display with 20 characters per line
Multilingual menu (English, German, French, Spanish, Italian, Bulgarian, Polish, …)
Complete device configuration via keypad, no additional software required
Integrated WLAN hotspot with full device access via web browser
Security code to protect configuration
Timestamped logging of important actions in the system logbook (device start, sensor failure, overrange, etc.)
Easy and fast cable connection with tool-free connectors
UV-resistant polycarbonate housing material, protection class IP 65
Persistent counter readings for up to 5 years
Integrated real-time clock,
battery buffered for 5 years
Standardization according to DIN 1343, DIN 6358, DIN ISO 2533, DIN 102/ISO 1-1975
Freely scalable current output for output of actual flow rate
Adjustable pulse weighting
(0.1, 1 or 10 or 100 m³ per pulse)
Optional data transmission via Modbus RTU and Modbus TCP
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 inputs are available as input signal for the measured values of the connected gas flow meters:
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.
The standardization can be performed 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.
All parameter settings/configurations can be carried out using the keys and the display or with a web browser via the integrated WLAN hotspot.
