1. INTRODUCTION
1.1. General notice
This operating manual provides assistance and instructions to clients of Kobold Messring GmbH for
the installation and configuration of the flow rate/totaliser when used in combination with a type DOG-
… oscillation flowmeter.
This operating manual is a supplement to existing documents, such as the data sheet and the
operating manual for the DOG-… oscillation flow meter.
This document is subject to change due to technical improvements. This version replaces all previous
versions of the document.
1.2 Device description
The flow rate/totaliser is a microcontroller-operated display device for the volume flow and total volume
flow of gases. Figure 1 shows a typical application of the flow rate indicator/totaliser.
Fig. 1: Typical application for the flow rate indicator/totaliser
The flow rate/totaliser is installed together with, and pre-wired to, a DOG-… transmitter in a control
box. A connector rail with all required inputs and outputs is provided for the user. The rail’s connection
layout is displayed on the switch box’s safety cover. Electric wiring must be done in accordance with
the wiring diagram following in chapter 4.
The flow computer is preconfigured by the factory. The table containing the factory settings can be
found in annexure D.
The measuring range and the K-factor are pre-set according to client requirements. Linearization is
switched off. The linearization settings should not be altered.
The analogue output (4-20 mA) is also factory-calibrated. Please do not change the settings in menu
points 75 and 76, as the calibration points will otherwise be altered.
The pulse output is scaled according to volume quantity (for example, one pulse every 12 m3). The
factory setting is one pulse per m3. The pulse duration can be adjusted between 0.0078 and
2 seconds. The standard setting is 0.0156 seconds.

2. OPERATIONAL
2.1. General
 The flow rate/totaliser may only be operated by personnel who are authorized and
trained by the operator of the facility. All instructions in this manual are to be observed.
 Take careful notice of the "Safety rules, instructions and precautionary measures" in
the front of this manual.
This chapter describes the daily use of the flow rate/totaliser. This instruction is meant for users
/ operators.
2.2. CONTROL PANEL
The following keys are available:
Fig. 2: Control Panel.
Functions of the keys

This key is used to program and save new values or settings.
 It is also used to gain access to SETUP-level; please read chapter 3.
 This key is used to SELECT accumulated total.
The arrow-key  is used to increase a value after PROG has been pressed
or to configure the unit; please read chapter 3.
Press this key twice to CLEAR the value for total.
 The arrow-key is used to select a digit after PROG has been pressed or to
configure the unit; please read chapter 3.

2.3. OPERATOR INFORMATION AND FUNCTIONS
In general, the flow rate/totaliser will always act at Operator level. The information displayed is
dependent upon the SETUP-settings. All pulses generated by the connected flowmeter are measured
by the flow rate/totaliser in the background, whichever screen refresh rate setting is chosen. After
pressing a key, the display will be updated very quickly during a 30 second period, after which it will
slow-down again. All information displayed is corrected by using the linearization table as stored in the
flow rate/totaliser.
Fig. 3: Example of display information during process.
For the Operator, the following functions are available:
 Display flow rate / total or flow rate
This is the main display information of the flow rate totaliser. After selecting any other
information, it will always return to this main display automatically.
Total is displayed on the upper-line of the display and flow rate on the bottom line.
It is possible to display flow rate only with the large 17mm digits; in this instance press the
SELECT-key to read the total.
When "-------" is shown, then the flow rate value is too high to be displayed. The arrows 
indicate the increase/decrease of the flow rate trend.
 Clear total
The value for total can be re-initialized. To do so, press CLEAR twice. After pressing CLEAR
once, the flashing text "PUSH CLEAR" is displayed. To avoid re-initialization at this stage, press
another key than CLEAR or wait for 20 seconds.
Re-initialization of total DOES NOT influence the accumulated total.
 Display accumulated total
When the SELECT-key is pressed, total and accumulated total are displayed. The accumulated
total cannot be re-initialized. The value will count up to 99,999,999,999. The unit and number of
decimals are displayed according to the configuration settings for total.
 Alarm 01-03
When "alarm" is displayed, please consult Appendix B: problem solving.

3. CONFIGURATION
3.1. INTRODUCTION
This and the following chapters are exclusively meant for electricians and non-operators. In
these, an extensive description of all software settings and hardware connections are provided.
 Mounting, electrical installation, start-up and maintenance of the instrument may only
be carried out by trained personnel authorized by the operator of the facility. Personnel
must read and understand this Operating Manual before carrying out its instructions.
 The flow rate/totaliser may only be operated by personnel who are authorized and
trained by the operator of the facility. All instructions in this manual are to be observed.
 Ensure that the measuring system is correctly wired up according to the wiring
diagrams. The housing may only be opened by trained personnel.
 Take careful notice of the "Safety rules, instructions and precautionary measures" in
the front of this manual.
3.2. PROGRAMMING SETUP-LEVEL
3.2.1. GENERAL
Configuration of the flow rate/totaliser is done at SETUP-level. SETUP-level is reached by
pressing the PROG/ENTER key for 7 seconds; at which time, both arrows  will be displayed.
In order to return to the operator level, PROG will have to be pressed for three seconds.
Alternatively, if no keys are pressed for 2 minutes, the unit will exit SETUP automatically.
SETUP can be reached at all times while the flow rate/totaliser remains fully operational.
Note: A pass code may be required to enter SETUP. Without this pass code access to SETUP
is denied.
To enter SETUP-level:

SCROLLING THROUGH SETUP-LEVEL
Selection of function-group and function:
SETUP is divided into several function groups and functions.
Each function has a unique number, which is displayed below the word "SETUP" at the bottom of the
display. The number is a combination of two figures. The first figure indicates the function-group and
the second figure the sub-function. Additionally, each function is expressed with a keyword.
After selecting a sub-function, the next main function is selected by scrolling through all "active" sub-
functions (e.g. 1, 11, 12, 13, 14, 1, 2, 3, 31 etc.).
