Page 5: Introduction
Page 5 INTRODUCTION 1.1. SYSTEM DESCRIPTION OF THE F126-P-EL Functions and features The flowcomputer Model F126-P-EL is a microprocessor driven instrument for the calculation of standard volumetric flow or mass flow for liquid applications using flow equations. This product has been designed with a focus on: ... - Page 6 Page 6 Configuration of the unit The F126-P-EL was designed to be implemented in many types of applications. For that reason, a SETUP-level is available to configure your F126-P-EL according to your specific requirements. SETUP includes several important features, such as K-factors, Span, measurement units, signal selection etc.

Page 7: Operational
Page 7 OPERATIONAL 2.1. GENERAL The F126-P-EL 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-EL will always function at Operator level. The information displayed is dependant upon the SETUP-settings. All pulses generated by the connected flowmeter are measured by the F126-P-EL 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 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 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.

Page 18: Analog Output
Page 18 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 19: Communication (Optional)
Page 19 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. -

Do connect the "-" to terminal 7 and the "+" to terminal 8. When power is applied to these terminals, the (optional) internal battery will be disabled / enabled automatically to extend the battery life time.
- Page 27 Page 27 Type AI: An isolated 4-20mA signal proportional to the flowrate is available with this option. When the output is disabled, a 3.5mA signal will be generated on these terminals. Max. driving capacity 1000 Ohm @ 30VDC. This option can be used with a battery powered unit but the life time of the battery is about 2 -3 years.
- Page 28 Page 28 Terminal 09-11; Flowmeter input: Three basic types of flowmeter signals can be connected to the unit: pulse, active pulse or sine- wave (coil). The screen of the signal wire must be connected to the common ground terminal 09 (unless earthed at the sensor itself).
- Page 29 Page 29 Pulse-signal PNP / PNP-LP: The F126-P-EL is suitable for use with flowmeters which have a PNP output signal. 3.2V is offered on terminal 11 which has to be switched by the sensor to terminal 10 (SIGNAL). For a reliable pulse detection, the pulse amplitude has to go above 1.2V.
- Page 30 Page 30 Reed-switch: The F126-P-EL is suitable for use with flowmeters which have a reed-switch. To avoid pulse bounce from the reed-switch, it is advised to select REED LP - low-pass filter (read par. 3.2.3.) NAMUR-signal: The F126-P-EL is suitable for flowmeters with an Namur signal. The standard F126-P-EL is not able to power the Namur sensor, as an external power supply for the sensor is required.
