Page 5: Introduction
SYSTEM DESCRIPTION OF THE F126-P-EG Functions and features The flowrate / totalizer model F126-P-EG-IA-TP is a microprocessor driven instrument designed for the calculation of corrected gas volume using flow equations. The unit displays compensated flowrate / total, line temperature and pressure. - Page 6 Page 6 Configuration of the unit The F126-P-EG was designed to be implemented in many types of applications. For that reason, a SETUP-level is available to configure your F126-P-EG according to your specific requirements. SETUP includes several important features, such as Span, measurement units, signal selection etc. All setting as are stored in EEPROM memory and will not get lost in case of power break-down or empty battery.

Page 7: Operational
Page 7 OPERATIONAL 2.1. GENERAL The F126-P-EG 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. -
Page 8: Operator Information And Functions
Page 8 2.3. OPERATOR INFORMATION AND FUNCTIONS In general, the F126-P-EG will always act function at Operator level. The information displayed is dependant up on the SETUP-settings. The signal generated by the connected flowmeter are measured by the F126-P-EG 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. -
Page 9: Configuration
Page 9 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. - Page 10 Page 10 Matrix structure SETUP-level: SCROLLING THROUGH SETUP-LEVEL Selection 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 function.

Page 14: Flowrate
Page 14 2 - FLOWRATE The settings for total and flowrate are entirely separate. In this way, different units of measurement can be used for each e.g. cubic meters for total and liters for flowrate. The display update time for flowrate is one second or more. Note: these settings also influence the analog output. -
Page 15: Power Management
Page 15 3 - POWER MANAGEMENT When used with the internal battery option, the user may hold the concern of reliable measurement over a long period of time. The F126-P-EG has several smart power management functions to extend the battery life time significantly. Two of these functions can be set: The calculation of the display-information influences the power LCD NEW consumption significantly. -

Page 19: Analog Output
Page 19 8 - ANALOG OUTPUT A linear analog (0)4-20mA or 0-10V signal is generated according to the flowrate with a 10 bits resolution. The settings for flowrate (SETUP - 2) influence the analog output directly. The relationship between rate and analog output is set with the following functions: The analog output can be disabled. -
Page 20: Communication
Page 20 8 - ANALOG OUTPUT (CONTINUED) This function is used to stabilize the analog output signal. FILTER The output value is updated every 0.1 second. With the help of this digital filter a more stable but less precise reading can be obtained. The filter principal is based on three input values: the filter level (01-99), the last analog output value and the last average value. -
