The Batching Master is a control instrument, especially designed for the automation of a batch function, where a precise result is required.
The Batching Master as a "stand alone version" is a fully functional device that requires just one power supply.
The operator has all the information that needed for a safe batching process local to the plant.
The batch is started directly at the point filling. If there is a failure in the system, the batch can be stopped immediately. Error messages are displayed in clear text.
Features
Local operation directly in the plant
Indication:
pre-set,
batched quantity,
flow rate and
grand total
Compatible with all flow meters and actuators
Highest accuracy due to a 4 20 mA output with a 5-step shut down ramp and soft start ramp.
PID controller for the flow rate or maintaining pressure
Communication with supervisory systems via Modbus protocol
Display functions for text indications and the entry of loading data
Approval for custody transfer
Precise Batching
The Batching Master opens the valve with a 4 - 20 mA output signal. Because of the soft start ramp and the 5 shut down steps also small quantities are filled with highest accuracy. "Hammers" in high flow rate system are prevented.
Flow meters
All types of flow meters can be connected. The input can be configured for:
current input (4 - 20 mA)
passive pulses
inductive sensors
Low flow rate monitoring
If the flow rate during the batch is too low, the Batching Master stops the batch after a pre-programmed time.
Sensor break monitoring
The Batching Master stops the batch if a sensor break with the mA input circuit or with the Namur contact input circuit occurs.
PID Controller function
Controlling the flow during the batch
Controlling the temperature or the PH during the batch
Pressure control function for LPG applications
Terminal function
The terminal function is controlled by the serial interface. The host system can send text messages to the display of the Batching Master.
Operator acknowledgements such as confirming plant status, entry of order numbers or selection of a product can be carried out using the keyboard.
Product routing via function keys F1 - F3
Easy-to-read display
Before the start of the batch, it is possible to chose a product way via the function keys.
Therefore it's possible to pre-program one question text and three texts that are dedicated to the function keys.
One digital output is dedicated to each function key.
Via this digital outputs it is possible to activate valves, pumps or product routings.
Batch systems for custody transfer
Approval No.:
German PTB.: 5.531/03.20
When tankers and wagons are loaded with a custody transfer batch system, it's not necessary to use expensive weighbridges. Also the dwell time for tankers being loaded will be reduced.
The batching data are logged to a printer. Using a multiplex system up to 16 Batching Masters can be connected at one printer. Different types of printers are available.
Validation of batch data
Some processes such as those in the pharmaceutical and toiletry industries require a batch report to validate the batch data.
This is carried out by a mini PC and a ticket printer. Many Batching Masters can be connected to the mini PC via an RS 485 bus. Before a batch can be started, up to 10 text strings can be entered into the Batching Master, e.g. Operator Name, Batch No. or Product Name. Operator prompts in the form of text can be programmed into the mini PC to aid operators to enter the correct information.
At the end of a batch, the programmed text, all operator entries and the batch data will be printed on the ticket printer.
