Batching Master 110i

Batching Master 210i

 

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.

Indication:

  • Pre-selection
  • batched quantity
  • flow rate
  • grand total

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 preprogrammed 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.

Low flow rate monitoring

If the flow rate during the batch is too low, the Batching Master stops the batch after a preprogrammed 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.

Digital inputs

Examples of the functions:

  • Purge function
  • Start, stop, set and reset
  • Releases for the batch
  • Switching on the controller function

Programming:

The programming  can be entered  in different languages, all program levels can be protected by codes.

Function keys F1 - F3



Examples for the functions:

  • Switching the purge function
  • Selection of 3 product ways
  • Selection of 3 pre-set values

Filling or emptying the batching system

Before starting the batching process, the measuring system can be filled, based on a predefined time or a “release” signal to be entered via an external digital input, indicating a full pipe. There are also functions  for emptying the system. During these processes the Batching Master doesn't count the flow.

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.

Storage of process data

Especially in the pharmaceutical industry, it’s important to store the information of the products that are filled during a batch. In this case, a printer is connected to the Batching Master via a multiplexing system.

The following data can be entered directly at the Batching Master:
User No., batch No., and product No.

The Batching Master provides the following information:
Date, time, current No., Preset and the batched quantity
