Batching and Loading Station Batching Master 210 i

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.

Precise batching

The Batching Master opens the valve with a 4 - 20 mA output signal. Because of the soft start ramp and the five shut down steps also small quantities are filled with highest accuracy. "Hammers" in high flow rate system are prevented.

No pressure "hammer"

in high flow rate systems. This is eliminated because of the soft start ramp and the shut down ramp of the 4 - 20 mA signal.

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

PID controller function (option)

controlling the flow during the batch
controlling the temperature or the PH during the batch
pressure control function for LPG applications (Application note LPG)

A flow controller that makes it possible to dose a product with a pre-programmable flow rate.
An override controller can keeping a second physical value during the batch. E. g. the emperature or the pressure of the product.

Terminal function

It is possible to use the Batching Master as an human interface to a supervisory system. It is possible that the user can enter an order number, an user access code or a product selection. The supervisory system communicates with the Batching Master via Modbus protocol. Up to 16 characters for two lines can be set via MODBUS interface. It is possible to get simple solutions with a ticket printer which delivers the entered data and the batch data after each batch.

Low flow rate monitoring

If the flow rate during the batch is to low, the Batching Master stops the batch after a programmed time. This function prevent an uncontrolled filling during a failure in the measuring system.

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

With digital inputs several functions are possible: Purge function, start, stop, set and reset, releases for the batch and switching on the controller functions.

Two customer specific error messages for release functions

Two release functions can be working via the digital inputs. If the digital input switches, then the batch will be stopped with the custom specific failure message. This messages with maximum 16 characters can be programmed via the Modbus interface. This messages have to be specified at the order placement

Automatic and manual filling/purge functions for the measuring system

For the emptying, cleaning or filling of the pipe system it could be necessary to open the batching valve. This can be done by a digital input or by the function key F1. During this time the flow rate signal will not be counted.
It is also possible to fill or purge the system automatic before each batching process for a programmed time or until a contact at a digital input indicates liquid in the pipe.

Product selection with three function keys

One digital output is dedicated to each function key. If a batch will be started only the digital output switches, which is dedicated to the chosen product way. A question text for each function key is possible. Via this digital outputs it's possible so activate valves, pumps or product ways.

Average density during the batch

Sometimes the density of the product is an important quality characteristic which has to be reported after the filling process. The density signal from the mass flow meter can be connected to analoge input 2 of the Batching Master. This information ar shown after pushing the RC-key

average density
actual density

These information are also available at the Modbus interface and can be can be printed in delivery papers.

Batch system for ultra pure water using a circulatory system

In this application the water flows continuously through a mass flow meter and then back into the circulatory system. The valve in the return line is controlled by a digital output of the Batching Master. After the start of a batch, the return flow valve will be forced to close and a pause time initiated. At the end of the pause time, the 4 – 20 mA output to the batching shut-off valve rises and the real batch begins. The Batching Master is programmed in a way that it only meters the flow when the real batch is running. (Application Note ultra pure water batch system)

Batch systems for custody transfer

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.
